Description

By the method through heat treated timber monitoring and control termite

Background technology

It is known to timber, being dried in timber preparation and preservation field.There are many methods to be used to dry timber.Having a kind of such method is that nature carries out for the timber remaining under atmospheric conditions, and for example the juggle on timber is aging.This dry water content that can reduce timber, and timber for example rots and catabiosis because fungal pathogens is easy to produce.The chamber that other dry technology utilization is added by heat, kiln for example, it maintains at elevated temperatures, and for example approximately 40 (Fahrenheits 105 degrees centigrade) are to the temperature between approximately 90 (Fahrenheits 195 degrees centigrade), to be dried quickly timber.The timber being dried is by this way used as timber traditionally, such as the timber for architectural engineering etc.Other traditional drying means utilizes high-temperature steam to the temperature between approximately 150 (Fahrenheits 302 degrees centigrade), to be dried timber in approximately 90 (Fahrenheits 195 degrees centigrade).Compare with preceding method, this temperature levels provides shorter drying time and the more stable timber of size.These traditional timber have approximately 15% to the about water content between 18% while conventionally selling on market.For example, once this timber in external environment, used a period of time in frame house, timber just can have approximately 10% to the about water content between 15%.

Another kind of traditional timber drying means even utilizes higher temperature, for example approximately 150 (Fahrenheits 302 degrees centigrade) change the color of timber self to the temperature between approximately 215 (Fahrenheits 420 degrees centigrade).The upper limit of heating can be higher than 215 above-mentioned (Fahrenheits 420 degrees centigrade), as long as temperature keeps below the temperature of burning of processed timber.This processing procedure is used to produce the outward appearance of painted timber traditionally, and does not use chemical stain agent.Because this timber is crossed the temperature be heated to rising, most water content removes from timber, make water content in heat treated timber approximately 2% to approximately between 10%.Although this method is known in timber preparation and preservation field, the timber product being produced by this method traditionally is not yet used as monitoring or controls the medium of termite.

In addition,, about the conventional art of termite monitoring and control and being taught as of knowledge, this timber can not be used to monitoring and control termite.First, think traditionally for example have approximately 10% and more can attract termite to the about timber of the high water content between 20%.Secondly, the timber being heat-treated by this way can produce than undressed timber or dry timber is more nonhygroscopic through heat treated timber product at a lower temperature.Like this, about the traditional view of termite feed, will show, this timber can be not attractive to termite, even for example, because can obtain the extra moisture situation of subsurface equipment (for), can stop the absorption of moisture through heat treated timber yet.---traditional viewpoint is thought---termite will can not be interested in to take food not absorb the words of moisture.

With this traditional view about termite food selection Comparatively speaking and understood with the past about the preferred thing of termite timber and instruction by contrast, the present invention utilizes thisly to be had relatively low water content and through heat treated timber, as food source and the decoy of termite, has obtained unexpected success than the timber of processing with traditional approach is more nonhygroscopic.Other advantage comprises that the resistance for microbiological attack strengthens to some extent and the amount of the extracted compound of the termite that can attract to look for food increases to some extent.Thus, utilize this termite monitoring through heat treated timber and control method to provide beyond thought advantage than more traditional termite station based on timber.

Embodiment

Referring now to accompanying drawing, Fig. 1 especially, an embodiment of termite station is overall to be represented with 21, and is depicted as being known as in this article of above-ground termite station and stocks the form of configuration (for example,, when encapsulating at first or in the not use time of termite station).The termite station 21 of this embodiment is a kind of above-ground termite stations, because its intention is used on soil, for example be fixed in suitable ground mounting surface, include but not limited on soil, the surface of approximate horizontal, inclined surface or vertically mounting surface is (for example, the inwall of house or building or outer wall, tree, fence column or pillar, etc.) on.Termite station 21 comprises the rectangle box-shaped container that overall use 23 represents substantially, it (or is base plate that this container has substrate 25 under the orientation shown in Fig. 1, broadly be called in this article the substrate of container), longitudinally relative end plate 27, laterally relative side plate 29 and lid 31 be (broadly, closure member), they limit the inner space 33 (Fig. 3) of container together.The end plate 27 of illustrated embodiment broadly defines the part of the sidepiece that is known as in this article container 23 together with side plate 29.Therefore, should understand, container 23 can be also the shape except the case shape of rectangle, and for example tubular (by having the sidepiece of general toroidal) or other suitable shape, as long as substrate 25, sidepiece limit the inner space 33 of container together with being constructed and arranged to lid 31.

Substrate 25 suitably has outer surface 35 (Fig. 4) and inner surface 37 (Fig. 3), and outer surface 35 is towards the mounting surface M (Figure 10) installing for termite station, and inner surface 37 also partly limits the inner space 33 of container towards the inside of container.Shown substrate 25 is rectangles, and be suitable for for general planar, or plane, makes when termite station 21 is installed the whole outer surface 35 of substrate substantially become the relative relation with being abutted against with mounting surface M.But, should be understood that substrate 25 can be also except general planar or plane shape, for example there is recessed, protruding or other nonplanar configuration, the not whole outer surface 35 of substrate is all abutted against in mounting surface, and this can not depart from the scope of the present invention yet.Shown end plate 27 and side plate 29 are also smooth or plane, and are oriented and are approximately perpendicular to substrate 25.Or end plate 27 and/or side plate 29 also can be not orthogonal to substrate 25, but for example outward-dipping with respect to substrate 25 or slope inwardly, and can not be also smooth or plane.Also can expect, end plate 27 and/or side plate 29 can be crooked, for example recessed or protruding, or are other non-planar configurations.In a suitable embodiment, container 23 can be by not formed by the preferential edible durable material of termite, for example acrylic acid or highstrenghtpiston.In another suitable embodiment, container 23 can be by not formed by the preferential edible Biodegradable material of termite, for example, by the derivative biopolymer of organic material.In a suitable especially embodiment, container 23 is substantially lighttight, although should understand this container, can be also roughly translucent or and even be transparent.

Especially with reference to Fig. 3,4 and 10, substrate 25 is more suitably configured to allow substrate itself (and thus termite station container 23) to be arranged on the mounting surface M of expectation.For example, in the embodiment shown, in substrate 25, become to separate relation ground, within peripheral edge 41, be formed with at least one and be more suitably a plurality of openings 39 with the peripheral edge 41 (Fig. 4) of substrate (" peripheral edge " of substrate be restricted to substrate with sidepiece as the intersection portion of end plate 27 and side plate 29).As seen best from Figure 11, shown opening 39 all has the shape (that is, consisting of the elongate slots intersecting) that is roughly plus sige or cross.But, also can imagine these openings 39 and also can be arbitrary shape and can not depart from the scope of the present invention.Also can expect, opening 39 needn't all be of similar shape.In the substrate 25 of illustrated embodiment, be formed with 11 such openings 39, one of its middle open placed in the middle (at vertical and horizontal on both) is arranged in substrate.Although the spacing between all 11 openings 39 is inhomogeneous, the spacing that should understand between opening can be also uniform.Should also be understood that the opening 39 that can form greater or less than 11 in substrate 25, comprise single opening.In addition, the in the situation that of there is a plurality of opening 39 in substrate 25 (as in the embodiment shown), the pattern of opening or arrange can not be also as shown in Figures 3 and 4.

These base openings 39 are for utilizing the suitable securing member that partly extends through described opening and enter mounting surface substrate 25 (and thus container 23) to be arranged on to mounting surface M as spiral fastener 43 (Figure 10).As shown in figure 11, each opening 39 at planar dimension (for example, length and width, or at opening, be diameter be circular in the situation that) the upper cross section of suitably being set for the axostylus axostyle that is significantly greater than securing member 43, make securing member to extend through described opening along larger fastener locations scope.Term " fastener locations scope " means along specific direction, to be arranged on the length of the open space in opening 39 for securing member 43 in this article.In a suitable embodiment, for example, the fastener locations scope being provided by opening 39 be securing member axostylus axostyle (, when substrate is fastened in mounting surface, extend through the part of described opening) maximum gauge at least about twice, be more suitably maximum gauge at least about three times, be even more suitably maximum gauge at least about 4 times.In other embodiments, the fastener locations scope being provided by opening 39 is in the scope of approximately 2 times to approximately 6 times of the maximum gauge of the axostylus axostyle of securing member, more suitably in the scope of approximately 3 times to approximately 6 times of the maximum gauge of the axostylus axostyle of securing member, even more suitably in the scope of approximately 4 times to approximately 6 times.In another example, the fastener locations scope that opening 39 as shown in Figure 11 and securing member 43 provide is at least approximately 0.25 inch (about 6.35mm), more suitably in the scope of approximately 0.25 inch to approximately 1.25 inches.

A plurality of such openings 39 are set in substrate 25 allows substrates (and thus termite station 21) to be arranged in the desired locations on mounting surface M, for example with one or more in described opening, be arranged on above the opening (not shown) being formed in mounting surface by termite, simultaneously for example, in more firm (, less impaired) of mounting surface or more strong portion's section, provide sufficient, can extend through the additional opening that substrate enters mounting surface for securing member 43.Thereby, in such embodiments, the quantity of opening 39 surpass for substrate is fastened on the securing member on mounting surface M quantity at least one.It is substrate 25 (parts a plurality of with it comparatively speaking) and termite station 21 is fixed on mounting surface M through the single structure parts of container 23 that opening 39 also allows by making securing member 43.For example, on the lid 31 of container 23, there is no opening (and these openings can will be used the in the situation that of traditional design), because mounting fastener needn't extend through this lid.This layout is easier to visually termite station 21, especially substrate 25 are placed in to the desired locations on mounting surface M, also allows to open and close and cover 31 when termite station keeps being arranged in mounting surface, especially needn't unscrew or remove mounting fastener.

Opening 39 in substrate 25 is also for the inner space 33 that termite entered and left container 23 through substrate 25 provides a plurality of inlet points.For this reason, as shown in figure 12, substrate is roughly cut sth. askew to its inner surface 37 from outer surface of substrate 35 at opening 39 places, or outside convergent (for example, planar dimension expands), make convergent portion as enter container 23 inner space 33 enter slope 45, thereby reduce or reduce as far as possible to enter the interruption that the termite of container runs into.For example, in one embodiment, tapered openings 39 limits slopes 45, this slope 45 from the outer surface 35 of substrate 25 to inner surface 37, take approximately 15 to approximately 60 degree, be more suitably the angles inclinations of approximately 45 degree.

Shown in the end plate 27 of container 23 and side plate 29 (being broadly sidepiece) in around the periphery of container, with spaced relation, be formed with periphery (that is, sidepiece enters) opening 47.More suitably, (these peripheral openings 47 extend to substrate 25 from corresponding end plate 27 and side plate 29, extend to the bight of end plate and side plate and substrate intersection), to allow for example sidepiece along the termite acupoint (Figure 10) forming along mounting surface M from container 23 but not enter its inner space 33 from the rear (that is, not by being formed on the opening 39 in substrate) of substrate of termite.In a suitable especially embodiment, the peripheral openings 47 being formed in end plate 27 and side plate 29 is extended in substrate 25, make contacting (that is, with substrate contacts) with container before in the interior further distribution in the inner space 33 of container 23 through the termite of peripheral openings.But within the scope of the invention, peripheral openings 47 might not extend in substrate 25.Also can imagine, substrate 25 can be for example to be chamfered or convergent with the similar mode of tapered openings 39 being formed in substrate on peripheral openings 47 and the ground of substrate contacts.

As seen best, be formed on a peripheral openings 47 in end plate 27 and respective peripheral register in relative end plate, the peripheral openings in a side plate 29 and respective peripheral register in relative side plate from Fig. 3 and 4.(be for example formed on the sidepiece of container 23, end plate 27 and side plate 29) in peripheral openings 47 allow termite stations 21 for example by disconnecting termite acupoint T and substrate 25 is rested on mounting surface M in the breaking part aliging with one or more peripheral openings at acupoint and being arranged on mounting surface M along acupoint T, as shown in figure 10.Should be understood that the peripheral openings 47 being arranged in container 23 quantity can greater or less than shown in quantity in container 23, comprise the situation of only having single peripheral openings, and can not depart from the scope of the present invention.

(as illustrated best in Fig. 4) in the embodiment shown, peripheral openings 47 is at least in part by corresponding path closure member 50 sealings, and closure member 50 can remove to provide the path through peripheral openings from container.This allows container around its periphery, roughly to be sealed except those peripheral openings 47 places of aliging in the termite acupoint with Figure 10.With reference to Figure 13 (the path closure member 50 arranging along the sidepiece of termite station 21 is shown) and Figure 14 (a path closure member in the bight that is arranged on termite station is shown), shown path closure member 50 connected removedly at peripheral openings 47 places, more suitably for can fragmentation maybe being ruptured, be connected to container 23, makes closure member can be removed from container (for example manually or utilize suitable blanking tool, pliers, screwdriver or other proper implements) to be provided to the path of the inner space of container.For example, in the embodiment of Figure 13 and 14, path closure member 50 is sentenced three connection width sheets 52 in corresponding peripheral openings 47 can be connected to container 23 by bad land.The cross section of path closure member 50 is roughly L shaped, has the base portion 56 of the erection part 54 of the part that is arranged in container 23 sidepieces and the part that is arranged in container substrate 25 of sealing peripheral openings of sealing peripheral openings.In a suitable especially embodiment, path closure member 50 form as one with container 23 molded the forming of a part of container 23 (for example, as).

But, also can imagine, path closure member 50 can form or be connected to removedly container dividually at peripheral openings 47 places and container, for example, use thermal weld, adhesive or other suitable interconnection technique, and can not depart from the scope of the present invention.Will also be understood that, in certain embodiments, path closure member 50 can (for example securely be connected to container 23 again, by adhesive, hook and ring fastener or other suitable machanical fastener), thus termite station 21 can be re-constructed and be reused to process different termite acupoints or other infringement within the scope of the invention.

In another suitable embodiment, as shown in Figure 15,15A and 15B, from container 23, saved path closure member 50.

The spacer element (for example, the projection 49 shown in Fig. 3, rib, projection or other suitable setting element) that is provided with one or more projections on the inner surface 37 of substrate 25, they reach the inner space 33 of container 23 from the plane of substrate.Especially, spacer element 49 forms (being for example, molded in the embodiment shown) with the substrate 25 of container 23.But these spacer elements 49 also can form dividually and for example be fixed on the inner surface 37 of substrate 25 by adhesive, welding or other suitable technique for fixing with substrate 25, and can not depart from the scope of the present invention.However, should be understood that these spacer elements 49 also can omit and can not depart from the scope of the present invention.

Get back to Fig. 1, lid 31 (broadly, the closure member of container 23) can be suitably configured between closed position (Fig. 1) and open position (Fig. 2), can touch the inner space 33 of container 23 at described open position.More specifically, shown lid 31 (is for example hinged on the peripheral sidewall of container, as in the embodiment shown, be hinged on one of container side plate 29, or be hinged on one of end plate 27), take with respect to container, more suitably as with respect to substrate 25 lid close and open position between make pivotal motion.For example, as seen from Figure 3 A, lid 31 can be hinged in the mode of " hinges " side plate 29, wherein cover rim attenuate or through the connection width sheet 53 of scribing, (for example form with side plate, molded), connect width sheet 53 enough flexible to allow lid to make pivotal motion with respect to side plate.However, should be understood that covering 31 also can form dividually with end plate 27 and side plate 29, and be mechanically hinged to end plate 27 and side plate 29 by suitable linkwork (not shown), and can not depart from the scope of the present invention.With reference to Fig. 3, (be for example provided with a traditional breech lock and buckle structure, as in the embodiment shown, on lid 31, one or more latch 55 are set, corresponding one or more fasteners 57 are set on the side plate 29 of container 23 and/or end plate 27, vice versa), for lid being releasably secured to its closed position.

In other embodiments, can imagine, lid 31 also can form with the remainder of container 23 dividually, and can whole be placed on the remainder of container or remove from the remainder of container.Should also be understood that other any suitable got loose fixed structure that can use except breech lock and buckle structure, so that lid 31 is releasably secured to its closed position, this also within the scope of the invention.Although the sidepiece of container 23 (in embodiment illustrated herein, end plate 27 and side plate 29) be fixed to substrate 25 (more suitably for form with substrate 25), but can imagine, described sidepiece also can be fixed to cover 31 and be hinged to substrate 25 and with lid together with its close and open position between locate, to be provided to the path of the inner space 33 of container.

One chamber 51 is suitably set size and is configured to be placed at least in part in container 23, more suitably for be positioned at all over the inner space 33 of container in the closed position of container cover 31.Especially with reference to Fig. 6, chamber 51 comprises one or more inner parts, is all inner part of termite station 21 in the embodiment shown.For example, in the embodiment shown, chamber 51 comprise assemble parts (totally representing with 61), with at least one bait base (totally representing with 63) and a retainer (totally representing with 65) that these gathering parts separate, this retainer is used for that gathering parts, bait base and retainer are remained to assembled state and usings as individual unit insertion container 23 and/or remove from container 23.It should be understood that, chamber 51 also can only comprise retainer 65 and gathering parts 61 or bait base 63 and can not depart from the scope of the present invention.In such embodiments, can imagine, from chamber 51 abridged parts, can otherwise be arranged on dividually in the inner space 33 of container 23 with chamber, or can be arranged on the outside of container, or can omit completely.

In one embodiment, assembling parts 61 and comprise decoy, is more suitably alleged in this article non-physical property decoy." non-physical property " decoy means not need to bring out the decoy of looking for food with termite physical contact (directly contacting) in this article.For example, in a suitable especially embodiment, non-physical property decoy comprises lower to heat treated timber in the temperature (for example,, at least about 150 (Fahrenheits 302 degrees centigrade), more suitably between approximately 150 degrees Celsius and 215 (Fahrenheit 420 degrees centigrade)) raising.

Timber is a kind of organic material being for example found, as the main component of the stem of wooden vegetation (, tree and shrub).Dry timber consists of the fiber of the cellulose (in dry weight, approximately 40% to approximately 50%) being kept together by lignin (in dry weight, approximately 25% to approximately 30%) and hemicellulose (in dry weight, approximately 20% to approximately 30%).Timber also comprises extract, and they are the compounds that can utilize various solvents to extract, and molecular weight is usually less than 500 grams/mol.In general, these extracts account for approximately 2% to approximately 8% (dry weight) of timber component.

Cellulose is part the abundantest in timber and plays a major role giving aspect its mechanical strength of timber.Cellulosic molecule is by forming to form the β of long linear chain-D-Glucose with β (1-> 4) key joint, and have hundreds of myriagram from thousands of to good/mole molecular weight.Strand in cellulose forms protofibril or micella.Micella align with the cellulose fibril that is orientated equidirectional and jammed tightly together with.Then cellulose protofibril and hemicellulose and colloid therebetween concurrently together with layering to form microfibril.When microfibril is gathered into larger bundle and be full of lignin in this structure, just produce fibril, it forms xylem fibre then.

Hemicellulose accounts for approximately 20% to approximately 30% of dry weight.The mean molecule quantity of hemicellulose is less than cellulosic molecule, in the scope of approximately 10,000 grams/mol to approximately 30,000 grams/mol.The composition of hemicellulose changes between hardwood (that is, oak, mahogany) and cork (that is, pine, cedar wood).The hemicellulose of hardwood is mainly glucuronoxylan (approximately 15% to approximately 30%) and a small amount of glucomannans (approximately 2% to approximately 5%).The hemicellulose of cork mainly consists of galactoglucomannan (approximately 20%) and a small amount of arabinoglucuronoxylan (approximately 5% to approximately 10%).

In timber, also find that there is colloid and starch, but amount is few conventionally, is all less than approximately 1%.Colloid is structurally similar to hemicellulose, on the anchor ring of middle lamella, primary cell wall and bordered pit, is found, and is present in fibrillar structure on a small quantity in addition.Starch can be found in the parenchyma cell of the nutrition deposit as the trees that live, and it consists of amylase and amylopectin.

Lignin is to have in configuration very diverse amorphous polymer.Lignin is usually counted as the glue of timber structure.The phenyl-propane unit of the framework of lignin structure based on three types: guaiacyl, lilac base and p-hydroxyphenyl.Cork is mainly by guaiacyl unit and a certain amount of p-hydroxyphenyl cell formation.By contrast, hardwood lignin is by lilac base and guaiacyl cell formation.

When timber is dried, these chemical compounds that form timber structure experience various variations.Especially, according to an embodiment herein, assemble parts 61 and be included in the timber being dried at the rising temperature between approximately 150 (Fahrenheits 302 degrees centigrade) and approximately 215 (Fahrenheits 420 degrees centigrade), at described temperature, these chemical changes are from as different in being dried down lower than approximately 150 (Fahrenheits 302 degrees centigrade) chemical change being produced in lower temperature scope.In another exemplary embodiment herein, assemble parts 61 and be included in the timber being dried at the rising temperature between approximately 185 (Fahrenheits 365 degrees centigrade) and approximately 215 (Fahrenheits 420 degrees centigrade).Especially, it is believed that, through heat treated timber, experience can be affected in timber for the free space of air and the variation of humidity.Especially, the porosity of timber and permeability change.The ratio of the volume fraction that porosity defines void space in solid.Permeability defines the diffusivity that fluid sees through porous body.

It is believed that, after this processing, porosity can increase, and the heating (for example, by evaporation) along with timber is removed with other compound because powerful, to be bound up on the structural liquid of timber.Separately, this variation will show that the heat treated timber of this process will be than the more moisture absorption of undressed timber, because there are more free spaces in timber.But this conclusion has been ignored treated timber and also can have been changed aspect permeability.There is permeability in the part that can interconnect each other in cell and/or space.For example, for hardwood, intervessel pit (intervessel pitting) can produce opening in film, thereby can improve permeability.But it is believed that, after this thermal treatment, these films may blocked or involucrum.This obstruction reduces overall permeability.In addition, described pit may also can be given vent to anger, thereby timber has closing cell's structure, and this can reduce overall permeability again.Also think, this thermal treatment meeting causes the remarkable partition of adjacent microfibril in the heat treated timber of process.And for live or without heat treated timber, these adjacent microfibrils can be provided for through the normal cross-layer dimension pipe stream of phloem and xylem organization, liquid being carried by the structure of timber.Due to their separation, in timber, can produce the partition that hinders liquid flow, thereby reduce hygroscopicity (that is, increasing hydrophobicity).Also think, the timber contraction of the increase producing under heat treatment temperature can increase the separation of adjacent xylem organization cell and adjacent phloem histocyte (that is, dimension solencyte), thereby suppresses liquid by histiocytic normal route.As skilled in the art can understand, initial porosity, permeability and the density of timber is depended in these variations, but it is believed that these variations are generally applicable to many timber kinds.In addition, this heat treatment process also may cause NM other variation herein and can not depart from the scope of the embodiment of the present invention the structure of timber and character.

Except the variation of hygroscopicity and hydrophobicity aspect, the timber being heat-treated by this way also comprises the variation relevant with other chemical compound on the cellulosic material being conventionally bound up in timber.Although do not belong to specific theory, but it is believed that, a part as heat treatment process, conventionally by these chemical compounds (for example, volatility, half volatile and compound (for example aromatic compounds) that can natural extraction, for example, especially from tannin, terpenes and oily derivative compound) be attached to the cellulosic connection of timber and interrupted, thereby rot to compare permission compound more easily from timber motion and enter timber region (for example, soil) around with traditional timber.Like this, these chemical compounds can extract or discharge and more easily scatter out from timber, thereby termite is attracted to timber.

To timber thermal treatment, generally carry out as follows by this way.First, timber is dried from timber, to remove most liquid.In one embodiment, dry run is carried out to the scope of approximately 175 (Fahrenheits 345 degrees centigrade) in approximately 110 (Fahrenheits 230 degrees centigrade).Then the timber of drying is heated to and maintains the temperature of a rising, for example, between approximately 150 (Fahrenheits 302 degrees centigrade) and approximately 215 (Fahrenheits 420 degrees centigrade), more suitably between approximately 185 (Fahrenheits 365 degrees centigrade) and approximately 215 (Fahrenheits 420 degrees centigrade).Can expect, in other embodiments, the temperature of the described rising that timber is heat-treated can surpass 215 (Fahrenheits 420 degrees centigrade), following to suppress burning or burning of treated timber as long as temperature remains on the ignition temperature of timber sample.Treated timber is suitably maintained this temperature and is reached the time that is enough to cause above-mentioned variation.In one exemplary embodiment, timber is maintained between the temperature approximately two hours to approximately three hours of described rising.Then the timber being dried is cooled as air cooling, liquid cooling or other known method by the suitable type of cooling.

In one exemplary embodiment, be dried through heat treated timber then can be partly by rehydration (moisturizing) the content liquid of cellulosic material is increased to approximately 1% to the about level between 18%.In another exemplary embodiment, through heat treated timber can be partly by rehydration to approximately 1% to the about level between 10%.In another exemplary embodiment, the timber being dried can be partly by rehydration to approximately 2% to the about level between 10%.However, it should be understood that, through heat treated timber needn't definite part by rehydration, thereby the content liquid being dried in timber is less than approximately 1%, and can not depart from the scope of the present invention.

Experiment

In this experiment, the sample evaluation of the white poplar timber being heat-treated according to a suitable embodiment and the white poplar timber processed with traditional approach is determined to North America reticulitermes flavipe (Reticulitermues flavipes) the feed preference between these timber samples.

The processed processing of timber being heat-treated is as follows.Timber is cut into common board size, for example 2 * 4 slabs of standard (that is, cross section is that approximately 38 millimeters (1.5 inches) are multiplied by approximately 89 millimeters (3.5 inches)).Then timber is placed in kiln or high temp/high pressure vessel.Temperature in vessel is increased to fast approximately 100 (Fahrenheits 212 degrees centigrade) and is held, until timber evenly reaches about 0% water capacity.Then temperature is stably elevated to and is maintained approximately 185 (the Fahrenheit 365 degrees centigrade) time of approximately 120 to 180 minutes.After dry, the temperature of timber is reduced to approximately 80 (Fahrenheits 176 degrees centigrade) between approximately 90 (Fahrenheits 194 degrees centigrade).During cooling with steam spray, reduce the temperature of timber and the water capacity of timber is increased to 2% to approximately between 10%.Whole heating and cooling process is wanted to complete for about 36 hours.

The white poplar timber of processing with traditional approach is dried approximately five to six days to the temperature of approximately 90 (Fahrenheits 195 degrees centigrade) in approximately 85 (Fahrenheits 185 degrees centigrade) in kiln.After dry, with the white poplar timber that traditional approach is processed, be allowed to be cooled to room temperature.

Described experiment utilizes selectivity and the biologicall test of non-selective laboratory to carry out.The object of research is based on associated (association) and/or consumes definite preference between above-mentioned two kinds of timber samples.For the biologicall test of selectivity laboratory, the sand that is 12% by 300 termites and 20 grams by weight (0.7 ounce) humidity adds in petri diss, and the average weight of two kinds of timber parts that is wherein arranged in double portion of corresponding phase of petri diss is all about 4 grams (0.141 ounces).Termite is placed between described timber part and timber movable and their preferences of consumption.After 31 days, calculate on each sheet timber or near termite quantity.In addition, termite is removed and weighs timber to determine consumption from timber.With 17 groups of 300 termites and new timber sample, repeat this Choice tests 17 times.

For non-selective biologicall test, the sand that is 12% by 300 termites and 20 grams by weight (0.7 ounce) humidity adds in petri diss, and wherein a kind of average weight of timber sample part is about 4 grams (0.141 ounces).Termite be placed in described timber part opposite and can be in test cavity freely-movable and consume this timber.After 31 days, termite is removed and weighs this timber to determine consumption from this timber.For each of two kinds of different timber samples (through heat treated and process with traditional approach), all use five groups of 300 termites and new timber sample to repeat this Choice tests five times.

Consumption in measuring for selectivity organism, the timber being heat-treated has at elevated temperatures been realized the mean consumption rate of every gram of termite every day 19.0 milligrams (every ounce of termite milli ounces every days 19.0), and the standard deviation of 17 Choice tests is 2.9.By contrast, realized the consumption rate of every gram of termite every day 15.1 milligrams (every ounce of termite milli ounces every days 15.1) with the timber that traditional approach is processed, the standard deviation of 17 Choice tests is 5.0.In non-selective biologicall test, the timber being heat-treated has at elevated temperatures been realized the consumption rate of every gram of termite every day 42.4 milligrams (every ounce of termite milli ounces every days 42.4), and the standard deviation of five non-selective tests is 1.6.By contrast, realized the consumption rate of every gram of termite every day 37.5 milligrams (every ounce of termite milli ounces every days 37.5) with the timber that traditional approach is processed, the standard deviation of five non-selective tests is 5.6.Like this, for selectivity and non-selective biologicall test, the timber being heat-treated is at elevated temperatures all than having realized higher consumption rate with the timber that traditional approach is processed.

In addition, when considering association during on-consumable, the par of termite that is arranged in petri diss half portion of the timber being heat-treated at the temperature that is included in rising in 17 selectivity organism determination tests is 183, and standard deviation is 34.By contrast, the par that is arranged in the termite of second half portion of petri diss that comprises the timber of processing with traditional approach is 72, and standard deviation is 40.Among 300 included termites of each experiment, on average there are 47 in experiment, to die.Even if the timber being heat-treated is at elevated temperatures done manyly, had inside water capacity still less than the timber of processing with traditional approach, also can produce this result.This very unexpectedly shows, the water capacity of the reduction of the timber being heat-treated at elevated temperatures can not hinder termite this timber of taking food, and even more unexpectedly, due to physics and/or the chemical property of this timber, it can attract more termite.Compare with the timber of processing with traditional approach, the termite in this research shows obvious higher attraction or preference for the timber being heat-treated at elevated temperatures.

In view of above-mentioned experiment, the non-physical property attraction of the increase of the timber being heat-treated at elevated temperatures can significantly strengthen the termite monitoring that comprises this timber and/or the effect of luring station with associated preference.As an example more specifically, shown gathering parts 61 comprise the entity timber piece 67 being heat-treated at elevated temperatures as mentioned above.However, should be understood that the timber being heat-treated of making gathering parts 61 also may be made in covering form, powder type or other appropriate format.Assemble parts 61 and also suitably there is no toxin.For example, above-mentioned do not have toxin interpolation or natural through heat treated timber.

In other embodiments, can imagine gathering parts 61 and also can comprise nontoxic physical property decoy, once contact the decoy that just can impel termite further to look for food with termite.The suitable example of these physical property decoys includes but not limited to, paper, cardboard, timber (for example,, except the timber being heat-treated as above) and other cellulosic material.In addition, can be individually or in conjunction with sugar (that is, wood sugar, mannose, galactose) with agar matrix and/or use cellulosic material through purifying as assembling parts 61 to utilize its water capacity and/or the decoy of taking food carrys out attract termites.

Bait base 63 suitably comprises nontoxic decoy, and can have or can not have for eliminating or suppress the toxin of termite attack.As an example, shown bait base 63 comprises the cellulose powder through purifying that is compressed into one or more tablets 69.In the situation that not having toxin to add bait base 63 to, bait base can be suitably for monitoring the existence of termite in the region of termite station 21.If there is toxin to add bait base 63 to, toxin is suitably one or more delays toxin of type that works, or is insect growth regulator, IGR, pathogene or metabolic antagonist.In the common name of transferring the possession of, be called and in the U.S. Patent No. 6,416,752 of " termite bait composition and method ", disclose a kind of such poison bait base 61 that has, whole disclosures of this patent are hereby expressly incorporated by reference.Should be understood that and also can use other suitable known monitoring and/or have poison bait sill and/or composition and can not departing from the scope of the present invention.In the embodiment shown, in chamber 51, use four such to have a poison bait substrate agent 69.But can imagine, also can use any amount bait base, comprise single bait base and can not depart from the scope of the present invention.

Shown chamber retainer 65 comprises glass portion 71, this glass of portion (for example become a pair of retort cup 73 by rough structure, the sidewall 79 that each retort cup has closed end 75, open end 77 and extends between them), this a pair of retort cup has portion's section of crossover, thereby described cup portion limits the bait base cavity 81 that is roughly 8-shaped.Cavity 81 suitably set size and be configured to by bait base 63 at least receive, more suitably for receiving and remaining on wherein, be more suitably by shown in circular tablet 69 in one or more receivings and remain on wherein.For example, the cavity 81 of Fig. 6 and 7 numeral 8 shapes is suitable for receiving therein and keeping at least two with side by side relationship, (for example to arrange, in each that limits described cavity, roughly in the cup 73 of tubular, have one) circular bait substrate agent 69, and (be for example more suitably dimensioned, set depth), to receive stacked a pair of tablet in each glass, wherein the exposed surface of the bait substrate agent of the top is substantially flush with the open end 77 of cup.However, it should be understood that, cavity 81 can shapelessly be also shape as shown in Figure 7, and the tablet 69 or other bait base that are arranged in cavity also can be configured as other shape except circle, and can not depart from the scope of the present invention.In addition, can imagine, chamber retainer 65 can comprise the cavity that two or more separate, rather than the single cavity 81 shown in Fig. 7.

Inner surface along each cup sidewall 79 is provided with a plurality of protuberances on longitudinally, for example, be the form of rib 83 in the embodiment shown, and described a plurality of protuberances extend laterally in the inside of cup 73 cavitys that form 81 by tubular roughly.For example, rib 83 shown in Fig. 6 and 7 extends to its open end 77 from the closed end 75 of cup 73 along longitudinally, and inwardly fully extend so that interference or the frictional fit of bait substrate agent 69 in cavity 81 to be provided, so that tablet is remained in cavity reliably from the inner surface of cup sidewall 79.However, should be understood that rib 83 needn't extend to open end 77 endlong from the closed end 75 of cup 73, this also within the scope of the invention.Also can imagine, also can bait base 61 be remained in chamber retainer cavity 81 with rib 83 or other suitable protuberance of more or less quantity.The spaced-apart elements that is provided with a plurality of projections 85 (Fig. 6 and 7) form at the closed end 75 of each glass 73 on the inner surface of cup portion 71, they extend in corresponding cavity 81.Spaced-apart elements 85 by tablet 69 and cup 73 closed end 75 separate to allow termite between them in the interior movement of cavity 81.In a suitable especially embodiment, spaced-apart elements 85 is provided by the corresponding hole 87 (Fig. 8) being formed in the outer surface of closed end 75 of each glass 73.These holes 87 are constructed and arranged to receive the spacer element 49 stretching out from the inner surface 37 of substrate 25, to allow, the stocking chamber under configuration and can be installed in fully in container 23 of termite station 21, the lid of container being closed.

Still, with reference to Fig. 6 and 7, chamber retainer 65 also has the tray portion 91 of essentially rectangular, and the cup portion 71 of this tray portion and chamber retainer forms as one and extends around cup portion 71, take by 61 receivings of gathering parts, more suitably as receiving and remaining in chamber retainer.The support plate 93 of shown tray portion 91 (for example, bottom) (tray portion 91 also comprises the peripheral sidewall 95 that limits the tray portion degree of depth) suitably on longitudinally, separate with the open end 77 of the cup 73 of tubular roughly, make the gathering parts 61 that kept by tray portion at least in part around the cup that is provided with bait base 63.But, can imagine, the support plate 93 of tray portion 91 also can be in the closed end 75 of cup 73 and the almost any position between open end 77 and can not departed from the scope of the present invention.In a suitable especially embodiment, the tray portion 91 of gathering parts 61 and retainer 65 size is relative to each other configured to provide assembles interference or the frictional fit of parts in tray portion, thus gathering parts is remained in retainer.As seen best from Fig. 6, define illustrated embodiment gathering parts 61 through heat treated timber piece 67, be roughly rectangle, and there is central opening 97, make timber piece when installing in the tray portion 91 of retainer 65 near the open end 77 at cup around cup portion 71 cup 73, make bait substrate agent 69 expose in central authorities simultaneously.

Suitable spacer structure is arranged under the work configuration (Fig. 9) of alleged herein termite station 21 at least a portion and the substrate 25 of assembling parts 61 is separated, to allow termite easily to move between gathering parts and substrate.For example, in the illustrated embodiment of Fig. 6, described spacer structure comprises four spaced-apart elements 99 that are fixed on heat treated timber piece 67, more particularly form as one with timber piece 67.Should be understood that and also can arrange greater or less than spaced-apart elements 99 shown in four.Described spacer structure also can be formed on to be assembled in parts 61, for example be formed on ditch, groove or other space in the outer surface of timber piece 67, make under the work configuration of termite station 21 the whole outer surface of timber piece not (for example,, except being provided with the place of ditch etc.) all rest on substrate 25.In the embodiment that can expect at other, one or more positions that suitable spacer structure can contact with gathering parts 61 under the work configuration of termite station 21 and the inner surface 37 of substrate 25 form as one, or separately form also mounted thereto.Although so not preferred, also should be understood that other suitable spacer structure also can be formed and maintenance and chamber 51 and container 23 both separate, and in container, be arranged between them, so that at least a portion and the substrate of assembling parts 61 are separated.

As seen best from Fig. 9, described spacer structure (for example, spaced-apart elements 99 in illustrated embodiment) outer surface inner surface 37 of substrate 25 (under the work configuration of termite station 21 towards) of assembling parts 61 is separated and is enough to allow termite assembling between parts and substrate the distance that moves freely (that is, needn't look for food through assembling parts).The spacing of more suitably, assembling between parts 61 and substrate 25 makes the feeler of termite when termite moves through gathering parts, can keep contacting with gathering parts.For example, described spacer structure can separate about 0.20cm to the distance of about 0.6cm with substrate 25 by assembling parts 61 in one embodiment.Spacer element 49 on substrate 25 suitably separates to allow termite to be moved between substrate and bait base in bait base 63 (for example, tablet 69) and substrate.

As seen best from Fig. 1 and 6, chamber 51 can comprise capping 101 alternatively, this capping is suitable for being releasably fixed to gathering parts 61 and/or chamber retainer 65, more suitably be fixed to the peripheral sidewall 95 of the tray portion 91 of chamber retainer, to limit arranging of chamber, assemble the inner space of parts and bait base 63 and reduce them to the exposure of air and other environmental aspect.However, it should be understood that, also can save capping 101 and can not depart from the scope of the present invention from chamber 51.

Referring again to Fig. 1 and 2, stocking under configuration of termite station 21, chamber 51 is arranged in the inner space 33 of container 23, wherein the outer surface of the closed end 75 of chamber retainer cup 73, towards the inner surface 37 of substrate 25, makes chamber cup portion hole 81 receive substrate spacer element 49 so that chamber is positioned in container.Thus under this configuration the capping 101 of chamber 51 towards the lid 31 of container 23 and lid in its closed position.For termite station 21 being arranged on the mounting surface M of expectation, container cover 31 is moved to its open position to be provided to the path of the inner space 33 of container 23, and chamber 51 is removed from container.Open and chamber 51 removes in the situation that covering as shown in figure 10 31, the outer surface of substrate 25 35 is placed on mounting surface M, and use suitable securing member 43 (that is, extending through base openings 39) that substrate (and thus container 23) is fixed in mounting surface.If also chamber 51 will be stocked to the configuration of stocking at termite station 21, by it, the orientation with regulation is put back in container 23 simply, and lid 31 is retightened in its closed position.

In order to monitor and/or process termite attack with termite station 21, lid 31 is opened and chamber 51 is removed from container 23.Chamber capping 101 (if any) is removed to expose gathering parts 61 and bait substrate agent 69 from chamber 51.Chamber 51 is started to reinsert container 23 from open end, make as shown in Figure 9, assemble parts 61 and towards substrate 25 and by spaced-apart elements 99 (broadly, spacer structure) and substrate, separate in addition now, and the agent 69 of bait substrate is separated by spacer element 49 and substrate.Then lid 31 is fixed on to its closed position so that chamber 51 is completely enclosed within container 23, thereby limits the work configuration of termite station 21.(for example assemble parts 61, in illustrated embodiment through heat treated timber piece 67), bait base 63 (for example, bait substrate agent 69) and chamber retainer 65 relative to each other set size and being configured to, make under the work configuration of termite station, assemble parts than bait base from substrate 25 more close to, and than bait base horizontal and vertical on both from be formed on peripheral openings 47 in end plate 27 and side plate 29 all more close to.

When work, for the termite station 21 being configured in its work configuration, along with termite approaches substrate 25 (or from after substrate from container 23 outsides, or from the sidepiece of container), their openings 39 in being formed on substrate or the peripheral openings 47 that has removed respective channels plate in being formed on end plate 27 and/or sidepiece 29 enter fast.Assemble parts 61 with respect to the installing and arranging of bait base 63 (that is, than bait base from substrate 25, end plate 27 and side plate 29 more close to) make termite first run into gathering parts after entering the inner space 33 of container.To assemble parts 61 be non-physical property decoy, as aforementioned, through heat treated timber piece 67 in the situation that, termite even can be aggregated parts and lures or attract in termite station 21.Being aggregated parts 61 induction finally can find bait base 63 and be lured and consume bait base 63 the interior termite of further looking for food of container 23.

In the situation that bait base 63 does not have toxin but is used to monitoring, termite leaves the visual trace of invasion and attack bait base, what for example when termite consumes bait, by them, formed detects acupoint so that leave the sign of termite attack on the surface at material, or through constructing the mud pipe (mud tubing) forming in the cup portion of material surface or injection chamber retainer.By adding toxin to bait base 63, the termite of looking for food food is got the bait that contains toxin, and a part of bait is taken back to nest through existing passage networking, thereby effectively disposes infringement.

Can expect, along with time lapse, will need to change chamber 51, for example, in long-term nothing, encroach on and be exposed to after environmental aspect, or for example, after the long-term infringement that has a large amount of bait bases 63 (, the tablet in illustrated embodiment 69) to be consumed.Can cover 31 by opening, remove old chamber (for example,, as individual unit) insert and to comprise that the new chamber of new gathering parts 61 and new tablets 69 changes chamber 51.Or, if do not need new gathering parts 61, can only in old chamber 51, change bait base 63 (for example, tablet 69), and old chamber is turned back in container 23 again.Owing to assembling parts 61, bait base 63 and retainer 65, as individual unit, be retained as assembled state, so whole chamber 51 is easily replaced and needn't enters in termite station 21, that is, only need to catch the cup portion 71 of retainer 65 and be pulled out to remove chamber from container 23.

Although the form that termite station is above-ground termite station in the embodiment of Fig. 1-15B, should be understood that the gathering parts that comprise the timber being heat-treated at elevated temperatures as described herein also can be used for the termite station in underground or ground.Subteranean termites station or other underground insect (for example, ant) station generally include station housing, and this station housing is placed in underground cavity and has therein opening to allow termite (or other insect) to enter in housing for subsequent treatment.In the common U.S. Patent No. 7 that is called " pest control device and method " that transfer the possession of, that authorize on August 8th, 2006,086, shown in 196, with an example having described suitable subteranean termites station, in the degree that whole disclosures of this patent conform at it, be hereby expressly incorporated by reference.However, it should be understood that, also can use other suitable subteranean termites station or other insect treating stations and can not depart from the scope of the present invention.

With reference to Figure 16 and 17, a kind of suitable subteranean termites station 510 comprises the housing 512 of basic hollow especially, and this housing has annular sidewall 514, top surface 516 and the basal surface 518 that defines internal capacity 520.A part for the top surface 516 of housing 512 is opened wide, and exposes internal capacity 520.Stand and 510 will assemble in the internal capacity 520 that one or more in matrix 522, monitoring container 524 and/or bait container 525 (not shown, but be described with reference to Figure 20 below) are received in housing 512.

On top surface 516, receive and have cover cap 528 with closure casing 512 removedly.Cover cap 528 is removably mounted on the top surface 516 of housing 512.In one embodiment, cover cap 528 has a pair of tab 530 of the groove 532 that stretches into the top surface 516 that is arranged in housing 512.Then counterclockwise or clockwise rotate cover cap 528 to engage cover cap 528.Described tab comprises oblique cutting part 534 along the leading edge 536 of tab 530.Along with cover cap 528 rotate in place, oblique cutting part 534 helps guiding tab 530 in place in groove 532.Also can use other for cover cap 528 is fixed to the appropriate device on top surface 516.

Preferably, housing 512 is formed by durable corrosion resistant material, for example acrylic acid or highstrenghtpiston.Although be depicted as, have the roughly shape of tubular, housing 512 also can be other suitable shape, for example rectangle arbitrarily.Preferably, stand and 510 there is the maximum height that is less than approximately 18 inches (457mm) and maximum gauge or the width that is less than approximately 12 inches (305mm), more preferably, this station has the maximum height that is less than approximately 9 inches (229mm) and the Breadth Maximum that is less than approximately 4 inches (102mm).

Stand and 510 comprise that at least one opening 537 of running through sidewall 514 is to allow termite to enter the internal capacity 520 with Departed Station.Preferably, in sidewall 514, there are several vertical elongated openings 537 that substantially extend in the whole length of sidewall.As used herein, " vertically " be used to refer to top surface 516 facing on direction time stand 510 preferred orientation.But can imagine, for described opening, also can use other shape and orientation.For example, described opening can be the elongated opening of level, or can be the circular open of arbitrarily arranging or form with repeating pattern.In addition, in basal surface 518, can there is the opening 537 that is directed to internal capacity 520.Or opening 537 is only formed in the bottom 538 of sidewall 514 of housing 512, it is imperforated making the top 539 of top surface 516 of the close housing 512 of sidewall 514.

In use, standing 510 is received in the addressable cavity of termite at least in part, simultaneously still can be by user from access on the ground.Described cavity can be underground cavity, or can be the cavity in the wall of building or other framework or in other superstructure.Described cavity can be formed in soil, or described cavity can be formed on paveio(u)r as in concrete or pitch, and soil is positioned at paveio(u)r below.Preferably, standing 510 is received in cavity substantially completely, makes to only have top surface 516 and the cover cap 528 can be from access on the ground.But in some cases, standing 510 can almost rest on the ground completely, makes cavity very shallow.

In one embodiment, as shown in figure 17, assemble matrix 522 and be received within the internal capacity 520 of housing 512, the bottom 538 of its adjacent sidewall 514 is settled, thereby elongated opening 537 is exposed to underground cavity by gathering matrix 522.Then, monitoring container 524 or bait container 525 are received within the internal capacity 520 of housing, assemble matrix 522 be accepted so that contiguous.Also can imagine, assemble matrix and can form pipe, and removable monitoring container 524 or bait container 525 be configured to be received in the hollow inside of this pipe.

Or, assemble matrix 522 and be directly received within cavity.For example, when assemble matrix 522 to be used in more durable environment (wherein the sidewall of cavity may around collapsed assembling matrix 522 hardly) as paveio(u)r in time, assembling matrix 522 can directly be placed in cavity.Then, monitoring container 524 or bait container 525 can be close to and be assembled matrix 522, be preferably sitting at and assemble matrix 522 tops and be placed in cavity.In such an embodiment, needn't receive and assemble matrix 522 and container 524,525 with a station.Then, can on cavity, install its design at suitable cover cap known in the art, so that gathering matrix 522 and

container

524 or 525 are fixed in cavity.But, in the above-described embodiments, assemble matrix 522 and be installed in cavity or station 510 in substantially fixed mode, thus minimum to the interference of gathering place and termite when

container

524 or 525 is examined, removes and/or changes.

Figure 18 illustrates an embodiment who assembles matrix 522.In an example shown, assemble matrix and form roughly tubular, make the outer surface 540 of assembling matrix when in place use in the face of the sidewall 514 at station 510 or the inner side of cavity.According to the cavity of receiving therein described matrix, the gathering matrix of other form can have the different geometry that is suitable for application.In an embodiment of the gathering matrix 522 in the internal capacity 520 that will be received in station 510, preferably, gathering matrix 522 has the similar shape of shape with housing 512, its width is slightly smaller than the inner width of housing 512, and making to assemble matrix 522 can be received in housing 512 removedly with snug fit (being slidably matched) relation.Preferably, assemble matrix 522 and have cavity 542, this cavity is centrally located on substantially to be assembled in matrix 522, is suitable for the gathering place as termite.Assembling matrix 522 comprises from outer surface 540 and inwardly to cavity 542, runs through the passage 544 of assembling matrix 522.Preferably, passage 544 is directed to the gathering place the cavity 542 of assembling matrix 522 by termite from outer surface 540.Preferably, assemble matrix 522 by attracting the cellulosic material of termite, make as timber.

Or, assemble matrix 522 and can be made by plastics or other suitable material, and be filled with cellulosic material, as paper, cardboard, compressed tablets or other suitable edible materials, and can there is the hole of the path that is provided to described edible materials.In this case, assemble matrix 522 textural can be similar with container 524.In addition, assembling matrix can be made by foamed material.In some such embodiment, assemble matrix and can not there is the void space that there is no material, but the material that matrix is still preferably configured to assemble in matrix or gathering matrix is that the termite eating will form gathering place in matrix.

Referring now to Figure 19, monitoring container 524 comprises cup 550.Cup 550 can have subsidiary lid 552.As shown, cup 550 has the basal surface 554 relative with lid 552, thereby the closed cylinder that monitoring container 524 is constructed to be limited with internal chamber 553 is with the configuration complementation with housing 512.Basal surface 554 is described as be in monitoring container 524 and is placed in 510 o'clock surfaces contiguous with assembling matrix 522, station with working method, and for simplicity, lid 552 comprises relative surface.But can imagine, monitoring container 524 also can insert and arrives at a station in 510 to cover the 552 contiguous states of assembling matrixes 522.The external width of cup 550 is slightly smaller than the inner width of housing 512 (Figure 16), and cup can be received in housing removedly.Preferably, container 524 is made of plastics.Referring now to Figure 20, bait container 525 preferably has with the structure of monitoring container 524 similarly constructs, and corresponding part represents with identical Reference numeral.

With reference to Figure 19 and 20 liang of figure, at the interior receivability of chamber 553 of monitoring container 524, there is the suitable material that can attract termite, as monitoring medium 555 (shown in Figure 19).At the interior receivability of chamber 553 of bait container 525, have and can attract the termite suitable material poisonous to termite again, as bait 557.Monitoring medium 555 and bait 557 are preferably the form that is easy to be inserted into the tablet in chamber 553.The use of monitoring medium 555 and bait 557 will be discussed below more fully.

Preferably,

container

524 or 525 and the pattern length of assembling matrix 522 be less than the length of housing 512, make the

container

524 or 525 can be not disturb the mode of installing with the top surface 516 of covering shell 512 of cover cap 528 to be received in housing 512.Preferably, for below, by the reason of discussing more fully, lid 552 and/or cup 550 are transparent (or transparent at least partly).

As shown in figure 21, cup 550 has at least one opening 566 in the basal surface 554 towards gathering

matrix 522.At container

524 or 525, with operating position, be received in housing 512 when interior, the opening 566 in basal surface 554 leads to the inside of cup 550, thereby allows termite to move to the inside of cup from assembling matrix 522.In basal surface, preferably there are a plurality of openings 566, but also can expect the design of single opening.For example, cup 550 can have the single opening 566 of shape slightly irregular (for example, cloverleaf).In addition can imagine, in some cases, cup 550 can have hole in its sidewall.The opening 566 that termite must arrive cup 550 from assembling matrix 522.In one embodiment, the ramuscule pin 568 on the basal surface 554 of cup 550 separates to be provided for by cup and gathering matrix 522 gap that termite is detected.

Monitoring container 524 is configured to the contiguous matrix 522 (seeing for example Figure 17) of assembling and is accepted replaceably, make to monitor container 524 and can be removed, check and/or change and can not disturb and assemble matrix 522, thereby keep by termite in assembling matrix 522, for example, in the interior any gathering place forming of cavity 542.Similarly, bait container 525 is configured to the contiguous matrix 522 of assembling and is accepted replaceably, makes in use, and the contiguous matrix of assembling of monitoring container 524 or bait container 525 is settled.

The lid 552 of container 524,525 also can have at least one opening 570 (seeing Figure 23), and this at least one opening allows termite to move into and leave container through the lid 552 of container.In addition, opening 570 prevents that container 524,525 from floating be filled with water in the situation that at station 510 or cavity.In addition, if the monitoring medium 555 or the bait 557 that are received in container 524,525 are immersed in water and expand, opening 566,570 can be provided for the space of expanding, but will remain in container by bait.The sidepiece 572 of cup 550 does not preferably have opening, makes to be driven to gathering matrix 522 downwards through the termite of the opening 537 in housing 512, thereby form initial gathering place in assembling matrix.But, when cup 550 is used as monitoring container 524, also can comprise opening at sidepiece.

Lid 552 is used suitable device to be arbitrarily removably mounted on cup 550.With reference to Figure 22, in one embodiment, cup 550 has several recesses 559 near its apical margin 558.Figure 23 illustrates the corresponding flange 560 of covering on 552, and they are received in recess 559 lid 552 is fixed on cup 550.Or the round thread portion (not shown) of cup 550 extends upward, and the complementary threaded base portion (not shown) of lid 552 is fixed on cup 550 removedly by screw thread.

At work, can or for installing other structure at described station 510, form the cavity of appropriate size at soil.Conventionally, gathering matrix 522 and monitoring container 524 are placed in the housing 512 of station, then station 510 are inserted or is pressed in cavity, until the top surface 516 of station housing 512 approaches soil surface.But, in some cases, for example, when known while having the condition that is beneficial to termite, may wish directly from using bait container 525 and assembling matrix 522 and start and do not use monitoring container 524.Or, gathering matrix 522 is directly placed in to cavity.Then container 524 or the 525 contiguous matrixes 522 of assembling are placed in to cavity.Explanation is below described as gathering matrix 522 to be placed in station 510, but can expect, also can be close to monitoring container 524 or bait container 525 and settle gathering matrix and do not use as described above station 510.Termite is because they are looked for food and look for food source and find station 510 and assemble matrix 522.

Along with termite is near 510 outside, station, they enter fast and move to inside and find and assemble matrix 522 through opening 537, and this is potential food source.Opening 537 in standing impels termite by sidewall 514, to be arrived and assembled matrix 522 fast.If termite enters and touch the

container

524 or 525 of assembling matrix 522 tops through opening 537, the imperforated sidewall of container is directed to termite downwards and assembles matrix 522 along elongated opening 537.Passage 544 impels termite to enter gathering matrix 522 and brings into use the internal cavities 542 being formed by matrix as assembling places.Cavity 542 forms the central dwell regions for gathering.Once to inner, they just can move and enter in monitoring container 524 towards the top of assembling matrix 522.Owing to only having monitoring container 524 to be removed to monitor termite activity, so assemble matrix 522, keep interference-free, thereby intactly maintained, assemble the cavity 542 of matrix 522 and gathering place wherein.

Can be by visually checking whether monitoring container 524 has the vestige of termite attack to come inspection post 510 to be termly subject to the sign of termite attack.To 510 the inspection of standing can as required or wish weekly, every two weeks, monthly etc. carry out.By removing cover cap 528 and visually checking the chamber 553 of monitoring container 524 or assemble matrix 522, check termite infestation.Due to termite infestation cellulosic material, as the character of monitoring medium 555 or gathering matrix 522, the visual trace of this invasion and attack or sign will be deposited on monitor unchangeably.What this sign was formed by them in the time of can being for example included in termite consumable material detects acupoint so that leave the sign of termite attack on the surface of material, and/or the mud pipe that structure forms on the inner surface of station housing 512 or monitoring container 524.The vestige of this infringement is apparent for the technical staff of termite infringement detection field.If found termite infestation, by changing monitoring container 524 to the bait of standing 510 times by bait container 525.Or removable monitoring medium 555 is also changed with bait 557.If do not find termite infestation, monitoring container 524 is put back to and arrived at a station 510.Cover cap 528 is put back to original position and inspection post 510 again behind reasonable time interval.

Consumption is assembled the termite of matrix 522 and will be found also the edible monitoring medium 555 nearby of monitoring container 524 that is arranged in then.These may be for one or more reasons.If monitoring medium 555 has than assembling matrix 522, more allow the packing (consistency) of termite preference, termite can stop consuming and assembles matrix 522 and before whole gathering matrix 522 has been consumed and then consume monitoring medium 555.If termite continues to consume, assemble matrix 522, when gathering matrix 522 is consumed completely, in normal termite is looked for food process, termite still can consume monitoring medium 555 then.Because monitoring medium 555 is positioned at nearby and has by the preferential character consuming of termite, so they can start to consume monitoring medium all the time.

Once find termite infestation monitoring medium 555 or assembled matrix 522, just with the 510 times baits in 557 pairs of stations of the bait that contains toxin.Preferably, monitoring container 524 is removed and is replaced by the bait 557 in container 525.The bait that contains toxin can be the form that the cellulose through purifying contains toxitabella.In the common name of transferring the possession of, be called in the U.S. Patent No. 6,416,752 of " termite bait composition and method " and recorded a kind of suitable termite bait composition, the disclosure integral body of this patent is hereby expressly incorporated by reference.

Toxin in bait 557 is preferably and postpones to work type or insect growth regulator, IGR, pathogene or metabolic antagonist.Preferably, it comprises the bait-less composition that is added with insecticide toxin.Can use for the present invention suitable termite insecticide ingredient arbitrarily.In one embodiment, the form that bait is tablet.For example, in a suitable embodiment, bait 557 comprises at least one compressed tablets, its have approximately 10 grams (0.35 ounces) between approximately 45 grams (1.6 ounces), more preferably between approximately 25 grams (0.88 ounce) to approximately 40 grams (1.4 ounces), the quality of approximately 35 grams (1.2 ounces) even more preferably.

Container 524,525 removing, checking and/or changing and can significantly not disturb the turnover path previously set up between the gathering place in termite colony or nest and gathering matrix 522 or the existing networking of passage in housing 512 because container 524,525 remove with replacement process in matrix do not move.Like this, to assembling the interference in the gathering place in matrix 522, be reduced to minimum, thereby reduced the termite possibility in place of abandoning taking food.In addition, the connected sum path between the container 525Yu termite colony of containing insecticide when replacing monitoring container 524 by bait container 525 is by Rapid Establishment.The termite food of looking for food is got the bait 557 that contains insecticide, also the poisonous bait of a part is taken back to nest through existing passage networking.

Stood for 510 time intervals with rule (for example, every 15 to 120 days) be examined, to assess the termite consumption degree of bait 557.When the bait 557 in container 525 has been consumed in a large number, can cover 552 and in container 525, insert more bait or simply by container being replaced by new container, add more bait by removing.Like this, in the normal inspection and/or Renewal process of container 524,525, assemble matrix 522 and do not remove, and be reduced to minimum to assembling the interference in place.May need periodic replacement to assemble matrix 522 (the gathering matrix 522 for example, more renewing every year).But this initiatively seldom carries out from assembling when take food in place termite.

According to for the treatment of insect, more suitably for processing underground insect, even more suitably for processing another embodiment of the method for subteranean termites, replaceable gathering matrix 522 ground or except assembling matrix 522 in the housing of station configuration herein described in previously through heat treated timber.For example, in one embodiment, assembling matrix can be formed through heat treated timber by described, but in addition to construct and to form with the mode together of the gathering matrix phase shown in Figure 16 and 17.In another embodiment, assembling matrix 522 can be formed through heat treated timber by described, but is configured in the housing of station with covering, powder, fragment or other particle form.In yet another embodiment, assemble matrix can with the gathering matrix phase shown in Figure 16 and 17 with mode construct and form, and can necessarily by described, through heat treated timber, be formed.In such an embodiment, can be in the housing of station contiguous assemble matrix settle extraly covering, powder, fragment or other particle form through heat treated timber.

In above-mentioned each embodiment, described wet environment around heat treated timber is suitably exposed to station housing (for example, malaria, soil and/or underground water), for example directly be exposed to station housing environment around, or be placed in the container that suitably can be seen through by liquid and through heat treated timber, be exposed under the moisture of container surroundings allowing.In this layout, in the time of under being exposed to sufficient moisture, contain through the liquid extract of one or more compositions of heat treated timber from described outside heat treated timber leaches the housing that arrives at a station and enter soil around.Described like this liquid extract broadly defines liquid decoy, and substantially formed station housing decoy district around further to attract the termite housing that arrives at a station.

For monitoring and/or control insect, be more suitably for monitoring and/or control insect, be even more suitably for monitoring and/or control another embodiment of the method for termite, from suitably producing the extract through heat treated timber through heat treated timber, then (be for example deposited in the region that will monitor and control, in the situation that not using station housing, deposit in cavity) for attracting and monitoring termite activity, be deposited in soil or other environmental externality of station housing in, and/or be deposited in the housing of station to discharge subsequently in the housing soil around that arrives at a station and absorbed by soil.As used herein; term " through the extract of heat treated timber " is intended to broadly refer to liquid extract; for example, through water extract or the non-water extract of heat treated timber, or refer to the solid extract (being for example solid, particle or other dried forms) through the liquid extract of heat treated timber.

As an example of a suitable especially embodiment, what make to be dried as mentioned above gets to produce the water extract through heat treated timber through heat treated timber experience water extraction.More suitably, according to a kind of method for generation of water extract, by special shape be dried through heat treated timber, be combined with a certain amount of water, and mixture is heated, more suitably for being heated to boiling point, reach the time at least about 10 minutes, more suitably in the scope of approximately 10 minutes to approximately 120 minutes, even more suitably in the scope of approximately 30 minutes to approximately 120 minutes.Then mixture is filtered to remove particle, thereby leave the water extract through heat treated timber of the extract of the heat treated timber that contains to hang oneself.Can imagine, liquid extract can be also produce to provide through the non-water extract of heat treated timber and can not depart from the scope of the present invention in water.But the liquid extract through heat treated timber producing by leaching process self is as decoy, or be used as in combination decoy with insect monitoring and/or control system (as the underground system of the overground system of Fig. 1-15B or Figure 16 and 17), to be conducive to attract insect, termite for example.

Experiment 2

In this experiment, the water extract through heat treated timber of the white poplar timber being heat-treated according to a suitable embodiment and filtered water evaluation are determined to the North America reticulitermes flavipe feed preference between these samples.

The processed processing of timber being heat-treated is as follows to produce water extract.Timber is cut into common board size, for example 2 * 4 slabs of standard (that is, cross section is that approximately 38 millimeters (1.5 inches) are multiplied by approximately 89 millimeters (3.5 inches)).Then timber is placed in kiln or high temp/high pressure vessel.Temperature in vessel is increased to fast approximately 100 (Fahrenheits 212 degrees centigrade) and is held, until timber evenly reaches about 0% water capacity.Then temperature is stably elevated to and is maintained approximately 185 (the Fahrenheit 365 degrees centigrade) time of approximately 120 to 180 minutes.After dry, the temperature of timber is reduced to approximately 80 (Fahrenheits 176 degrees centigrade) between approximately 90 (Fahrenheits 194 degrees centigrade).During cooling with steam spray, reduce the temperature of timber and the water capacity of timber is increased to 2% to approximately between 10%.Whole heating and cooling process is wanted to complete for about 36 hours.

With mechanical means, grind through heat treated timber, until the particle size of material is in the scope of 1 to 250 micron.Then approximately 1/3rd the measured quantity that equals standard U.S. gallons of fluid volume is placed in to filtered water and boils time of 20 minutes.After boiling, allow water/carry out through the mixture of heat treated timber coolingly, then filter from mixture, to remove particle, thereby leave the water extract through heat treated timber.

The filter paper of Whatman board (Cat.No.1001-150 (150mm diameter)) is immersed in the water extract of heat treated timber and allows air-dry.Other filter paper is for example immersed in, in filtered water (, there is no the extract through heat treated timber) and allows air-dry.Then above the termite attack soil in glass jar, separate the filter paper of laying drying in approximately 12 inches of places and reach two time-of-weeks, visually check during this period glass jar and observe termite activity.After two weeks, visible observation shows, uses the filter paper of processing through the water extract of heat treated timber to be eaten in a large number and penetrate, and the filter paper of processing by filtered water has the edible activity of much less, and does not find edible activity in some cases.

For monitoring and/or control insect colony, being more suitably a suitable embodiment of the method for termite colony, by the water extract through heat treated timber, (be broadly, liquid extract through heat treated timber, be more broadly, through the extract of heat treated timber) be transported to the station housing of termite monitoring and control system (as system or other suitable system of the system of Fig. 1-15B, Figure 16 and 17).For example, for the underground system shown in Figure 16 and 17, the in the situation that of in station housing has been placed in cavity, water extract through heat treated timber is poured into downwards in the housing of station, make extract through station the opening in housing run out of station housing and disperse to arrive at a station in housing soil around, with the outside at station housing with form decoy district around.In other embodiments, in the time of in the water extract through heat treated timber is introduced into station housing, assembles matrix (be other parts in some cases, for example, monitor container) and can be loaded in the housing of station.

In another embodiment, liquid extract through heat treated timber is capable of loading and carrying on suitable carrier or in carrier, (be for example for example immersed in substrate, cardboard, paper, timber or other suitable substrate) in or be coated in substrate, or be included in and allow in suitable container (broadly, carrier) that solution spills.In such embodiments, can be using described carrier as assembling the replacement of matrix or additional and be placed in the station housing of overground system (Fig. 1-15B) or underground system (Figure 16 and 17).On the other hand, be added with before the substrate carrier of the liquid extract of heat treated timber can be in packing substrate into station housing and be dried.

In other embodiments, can make to process through the liquid extract experience desolventizing of heat treated timber, such as but not limited to extract boiling down, freeze drying, steam induction evaporation mode, other suitable desolventizing being processed or their any combination, to produce solid form (, solid matter or particle, as powder or crystal form) the extract through heat treated timber.Then can by the described extract through heat treated timber with the liquid extract with through heat treated timber and/or aforementioned particles shape through the identical mode of heat treated timber be placed in station housing.

When introducing the element of the present invention or embodiment, article " " and " described " mean to exist one or more these elements.Term " comprises ", " comprising " and " having " mean included and mean other element that can exist except listed element.

Therefore owing to can the said goods and method being made various changes and can not be departed from the scope of the present invention, be contained in the above description and illustrate that all the elements in the accompanying drawings should be interpreted as descriptive and nonrestrictive.
