Abstract

Disclosed is a device for controlling insects, comprising a paper support that can burn slowly. The inventive device is characterized in that the same is provided with at least one insecticide.

Description

Insecticide-impregnated paper {PAPER IMPREGNATED WITH INSECTICIDES}

The present invention relates to paper impregnated with pesticidal active substances, to a process for preparing the same, and to the use thereof for controlling insects.

For example, it is known that what is known as a steam generating tablet can be used to kill or control insects, for example mosquitoes, using a heating device. In this method, suitable materials such as cellulose and cotton cardboard, asbestos, ceramic and / or porous resins are impregnated with the pesticidal active substance solution to obtain pesticide tablets. The pesticide is evaporated by the action of a heating device which generates a temperature of 120 to 190 ° C.

A substantial disadvantage of these steam generating tablets is that the release of the active substance is not uniform over the expected duration of action. When they are brought into the working state, the release of the active substance is usually unnecessarily high, and then continuously drops rapidly. The activity of these steam generating tablets is reduced during a given period of use.

For example, the steam generator described in GB-B-2 153 227 has also been known for some time on the assumption of household; Here, the solution is evaporated by an electrically heatable wick and the active substance is dissolved in, for example, a mixture of saturated aliphatic hydrocarbons.

When a product is used, the amount of organic solvent required for such a so-called liquid evaporator, which is significant compared to the amount of active substance, leads to an undesirably high solvent concentration in the room, particularly fouling the walls of these devices and objects near them. It has often been a complaint from consumers.

In order to control annoying insects, a battery insecticide evaporator is known (DE 195 25 782 A1), in which the surface of the radiator slab is heated to a temperature of 90 to 130 ° C. to evaporate the insecticide.

In addition, DE 20 2004 008 226 U1 has a citronella oil content and comprises a pore and / or spaced support, and a fuel consisting of wax and / or paraffin and / or stearin, in particular on insects Disclosed is a fuel product for salvage.

It is also known to evaporate pesticides using an electric fan that blows airflow onto a support impregnated with a pesticide active material solution. Such fan systems are described, for example, in WO-A-96 / 32843.

EP-B-0 279 325 discloses natural and synthetic materials impregnated with transflutrin, including, for example, moth paper.

DE 199 47 146 A1 discloses a support material impregnated with 0.05 to 2 mg / cm 2 of the active substance of the series consisting of transfluthrin, pinamine forte, bafortrin and pralaterin. Supports are used at room temperature to control wing insects in confined spaces. As a result of the volatilization of the pesticidal active substance, the latter is released from the support material, thereby ensuring a constant concentration of the pesticidal active substance in the air. However, the drawback of the systems described in DE 199 47 146 A1 is that these systems firstly release pesticidal substances during long-term storage, and if the system is used later, the activity of the already stored system actually appears to the user. It is not clear. Second, the release of pesticidal actives out of the system is not effective enough.

In addition, for example, terrace, smoke coil to protect it from the balcony, small insects from camping or room for 6 to 12 hours, for example, Bay gun (Baygon) ^® coil are known. In use, the ring is lit in the process of the ring glowing so that the contained active substance is released slowly and continuously in the open air or indoors. A room about 20 m 2 in size requires one commercial ring. However, a disadvantage of these rings is that only some of them are used since they tend to break in use.

Aerosols or oil sprays are also used to exterminate insects to quickly get rid of them in confined spaces. Thus, the treated space can then be air treated as long as the appearance of new insects can be prevented. However, a disadvantage of this system is that the aerosol mist or oil spray mist will not be finely distributed in the room as a result of the bulk of the system.

All these products are expensive to produce, due to technically complex and time-consuming features of transportation. In addition, the production of aerosols, oil sprays and spirals, which represent the volume of the product as a whole, requires the use of large amounts of natural resources such as kerosine, propane / butane, wood glue, starch and various formulation aids. In addition, their use usually results in later disposal of related packaging such as tins, pans, plastic bottles, outer packaging and the like.

In view of the prior art mentioned above, the expert thus mainly faces the problem of providing a device for controlling insects which can avoid the above mentioned disadvantages.

In the first embodiment, the solution of this problem begins with a device for controlling insects with a glowing support.

The support is then characterized as having at least one pesticidal active substance.

According to the invention, therefore, in the first embodiment, there is provided an apparatus for controlling insects, which can be glowing and comprises, for example, a support having at least one pesticidal active substance by impregnation. According to the present invention, the support is designed so that once the flame is lit, for example by blowing or blowing, the fire continues to glow and not completely extinguish. As a result of the glowing, the support releases at least one pesticidal active substance to control insects.

Support

For the purposes of the present invention, the support is not particularly limited as long as it can release at least one pesticidal active substance during the glowing.

Suitable supports are, for example, cellulosic supports. In this regard, examples that may be mentioned include paper supports described in more detail below within the scope of the preferred embodiments. Other cellulosic materials are, for example, wood chips, wood chips or sawdust, rice husks, corncob spindles (preferably grain free), pecan nut husks and peanut husks. Thin particle boards are also particularly suitable as support materials. Suitable cellulosic supports are described, for example, in German patent application DE 43 223 76 A1, the disclosure of which is incorporated herein by reference.

Another possible support is based on a fabric material. Such supports may be partly or wholly, for example synthetic or natural fibers made of polyester or nylon, such as cotton, viscose, linen / viscose mixtures, or mixtures of synthetic and natural fibers, such as cellulose polyesters ( Synthetic paper) or cotton polyester. Other examples are wool feltine and Trevira satin.

Another possible support is based on glowable plastic materials such as polycarbonates, polyesters, polyamides and polyterephthalates. Thus, it has been found within the scope of the present invention that the support element for the pesticidal active material can be made of plastic material into which the active material is incorporated before the support element enters the final production or shaping process. Such active materials, within the scope of the present invention, are capable of being released from the plastic support at a substantially constant evaporation rate as the support glows, while being characterized by their activity, which is only negatively affected by the shaping process of the support element or only in minor amounts. Are distinguished by. Selection methods for the preparation of the support, in particular, include mixing the pesticidal active material, for example pyredoid, with a plastic starting material, for example polycarbonate, and then processing the mixture in an injection molding mold to give the final form described. Injection molding method. Examples of other manufacturing methods are extrusion or thermoforming.

Within the scope of the present invention, the use of cellulosic supports is particularly preferred.

Within the scope of the invention, the use of paper supports is also particularly preferred.

In a particularly preferred embodiment, the solution of the problem on which the present invention is based thus starts with a device for controlling insects comprising a glowable paper support.

The paper support is characterized by having at least one pesticidal active substance.

According to the invention, therefore, in this particularly preferred embodiment there is provided an apparatus for controlling insects which can be glowed and comprises a paper support having at least one pesticidal active substance, for example by impregnation. According to the present invention, the paper support is designed so that once the flame has set, for example, by blowing off or blowing off, it continues to glow and does not go out completely. As a result of the glowing, the paper support releases at least one pesticidal active substance to control insects.

In a particularly preferred embodiment of the invention, the device of the invention consists of a support, in particular a paper support, at least one pesticidal active substance and, if appropriate, further additives, for example potassium nitrate. Additional additives are described below.

Cellulose Supports-Paper Supports

According to the first embodiment, the apparatus of the present invention comprises a paper support. The paper support contains cellulose. Cellulose, within the scope of the present invention, is obtained from the chemical digestion of plant fibers (in most cases wood) and is meant to mean biomass consisting mainly of cellulose.

Paper supports of the type of the invention have been known for many years but are not in the field of insect control. Thus, the paper support has been impregnated with Asian tree resin "styrax" for about 150 years, and the resulting product has been named "Armenian Paper". These "Armenian papers" are used to neutralize food and tobacco odors or other unpleasant odors. Auguste Poncet, a Frenchman, returned to Armenia from a trip with a resin, which is also used in the manufacture of spices, reminiscent of the smell of incense. Paper is sold in booklets with varying number of sheets. If such paper is used, remove one sheet from the booklet so that it glows slowly, turn the ashtray on, and then turn off the light. During the glow, the paper releases the desired fragrance, ensuring a nice fragrance around it. The paper substrate of the present invention is also used in a similar manner.

In principle, the paper support used for this purpose can usually absorb at least one suitable pesticidal active material and, after the paper support is turned on and off, can release the at least one pesticidal active material substantially without causing degradation. As long as it exists, it is not specifically limited.

However, the paper weight is preferably 25 to 300 g / m 2, especially 25 to 270 g / m 2, particularly preferably 25 to 250 g / m 2, particularly preferably 25 to 230 g / m 2, particularly preferably 25 It has been found that paper supports of from 215 g / m 2, in particular from 25 to 200 g / m 2, are particularly suitable for the purposes of the present invention.

Further, the thickness of the paper support is in the range of 0.1 to 0.5 mm, particularly preferably 0.15 to 0.45 mm, particularly preferably 0.15 to 0.40, particularly preferably 0.15 to 0.34 mm, especially 0.15 to 0.32 mm.

As for the size of each paper support, the present invention is not limited. However, the paper support of the present invention is ready to be cut by the user so that it can be used in a suitable way, ie, sized to enable the paper support to be glossy, for example in a container, for example an ashtray. It must exist in form.

For example, a paper support that can be used in accordance with the present invention can take the form of a support, for example, paperboard, for example absorbent paperboard, cardboard or cardboard.

Insecticide active substance

Supports with only one pesticidal active material, in particular paper supports, can be used in the device of the invention. Alternatively, it is also possible to provide two or more pesticidal active substances, for example two, three or four pesticidal active substances, simultaneously on a support, in particular a paper support.

The selection of a suitable pesticidal active material is in principle limited only to the release of the pesticidal active material into the surrounding air without substantially degrading at the glowing temperature of the support, in particular of the paper support, without loss of pesticide. . The term "without substantially degrading" within the scope of the present invention means that the decomposition takes place up to 80%, preferably up to 70%, particularly preferably up to 60%, in particular up to 50%, in particular up to 40%.

matrix

Insecticidal active substances may also be present on the support of the matrix, in particular on the paper support. By using the matrix material containing the pesticidal active substance, since the pesticidal active substance is not substantially released after the preparation of the product of the present invention and before its use, it is possible to ensure that the product of the present invention does not change its concentration. .

Suitable matrix materials are all systems which prevent at least one pesticidal active material used according to the invention from escaping from a support, for example a paper support, under ordinary environmental conditions (23 ° C., 1013 mbar).

Organic materials suitable as matrix materials include polyvinyl alcohol, wheat protein and derivatives thereof, carbohydrates, starches (from different botanical sources), amylose and derivatives thereof, amylopectin and derivatives thereof, cellulose and derivatives thereof, hydrolyzed starches, processed starches, processed Starch derivatives, maltodextrin, hydroxypropylmethylcellulose (HPMC), polyvinylpyrrolidone (PVP), chitin, chitosan, polysaccharide resins and derivatives thereof, polyethyleneglycol, polyester, hydroxyalkyl starch, polyvinylpyrrolidone / Cellulose derivatives, casein, gelatin, solubilized protein, polyacrylamide, polyamine, styrene / maleic anhydride resin, polyethyleneamine, and xanthan gum.

Another example that may be mentioned is polyacrylates such as optionally crosslinked maleated or epoxidized polymers and crosslinked (meth) acrylate polymers. Preference is given to condensates of maleated or epoxidized polymers with crosslinkers, preferably polyamines. Examples of suitable polymers include the reaction products of polydienes such as polybutadiene, polydecaddiene and soybean oil with molecular weights greater than 400 g / mol, maleic anhydride, also copolymers of olefins such as ethylene and maleic anhydride, and epoxidation Polybutadiene. Preferred crosslinkers are polyamines, in particular polyoxypropylenediamine and polyoxypropylenetriamine. Other materials also suitable as crosslinkers are triethylene glycol, polyethyleneimine and urea. The crosslinking reaction is preferably carried out in an alcohol solution such as dipropylene glycol at high temperature. Maleic anhydride or epoxide groups or -NR-CO- groups and -CRH-O- groups of the crosslinked polymers given by the polyoxyalkylene polyamines have a hydrophilic effect.

Another class of crosslinked polymers is monofunctional (meth) acrylate monomers such as hydroxyethyl acrylate or poly (propylene oxide) (ethylene oxide) monomethacrylate, polyfunctional (meth) acrylate monomers, For example, it is a copolymer of ethylene glycol dimethacrylate or polyethylene glycol 400 dimethacrylate. The preparation of the crosslinked (meth) acrylate polymers is accomplished by free radical copolymerization of the monomers. In either case, the crosslinked polymers can absorb liquids and gases, such as pesticides, which are finely distributed in liquid, dissolved or dispersed form.

Suitable as matrix forming agents are solid alkancarboxylic acids and gel-like metal salts of alkancarboxylic acids. Preferably, the following may be mentioned: Alkali metal salts of stearic acid and stearic acid, such as sodium stearate, and mixtures of stearic acid and palmitic acid or alkali metal salts thereof, such as sodium stearate and sodium palmitate . Suitable matrix formers are described in DE 196 24 819 A1, the disclosure of which is hereby incorporated by reference.

Further examples that may be mentioned are inorganic materials such as silica, polysilicates, polyphosphoric acid and derivatives thereof, polyboric acid, clays and the like.

It is also possible to use microencapsulated insecticidal active substances. As a result of the microencapsulation of each pesticidal active substance, unwanted release under standard room conditions can be avoided. Suitable systems are described in DE 100 22 989 A1, the disclosure of which is hereby incorporated by reference.

4.2 Procedure

Before starting the test, check the specimen clearly.

Care must be taken to insert the specimens to be tested into a given clamping device and to arrange them so that they do not come into contact with other surfaces such as the floor or receiving dish during the test (glowing of the specimen).

Place the specimen in a test chamber (1 m 3 or 20 m 3) so that the specimen can be observed throughout the entire test step. For tests in a 20-m³ chamber, the fan can be used arbitrarily to simulate air circulation (positioning: see diagram below). Light the specimen with a lighter until the flame is visible. Blow out the flame immediately so that the specimen can continue to glow independently. At the same time, start the stopwatch to measure the glowing time of the specimen. The specimens were observed over the entire test period (glowing period) and observed as follows:

The specimen continues to glow from beginning to end.

-The specimens glow only uniformly or only partially from beginning to end.

-Part of the specimen is reduced in gloss upon testing.

At least three measurements are taken.

5.2 Pretreatment of Paper

The paper measured for pretreatment was cut to DIN A 4 size and clearly identified with the corresponding developer. The DIN A 4 paper sheet was accurately weighed (net weight).

Thereafter, 500 g of 6% KNO ₃ aqueous solution was prepared. Care should be taken that deionized water is used for the preparation of the solution. The finished solution is identified by the corresponding number of developments and transferred to a V4A dish having a total volume of about 1 l. The paper is immersed in a 6% concentration of KNO ₃ solution. Care should be taken to ensure that the entire DIN A 4 paper sheet is immersed in the solution. After 20 minutes, the paper sheet is removed from the solution and pressed directly using a photographer's roller press to draw excess fluid out of the paper.

After pressing, the paper sheet is dried to constant weight in a drying oven (at about 50 ° C.) and again weighed correctly (gross weight).

The finished pretreated paper sheet is cut into 12 × 2 cm test piece strips and checked appropriately.

5.3 Impregnation of Test Strips

Using an Eppendorf pipette, a limited volume of active material solution is placed on the test strip. Care should be taken to ensure that the total amount is evenly distributed over the surface. The impregnated test piece strips are identified by the relevant number of developments and sealed with aluminum foil. After an exposure time of at least 24 hours, the specimen strip can be removed from the aluminum foil for related testing. It is important to prepare sufficient amounts per test strip so that intended tests, such as tests on biological activity and subsequent analysis, can be performed. Store the specimens for later use in the refrigerator.

5.4 Evaluation of KNO ₃ Amount

The evaluation of KNO ₃ amount is done as follows:

- KNO ₃ Volume / DIN A 4 Sheet

Gross Weight Paper Sheet-Net Weight Paper Sheet = KNO ₃ Quantity

-KNO ₃ Weight average

KNO ₃ quantity per sheet × 1 m² / area DIN A 4 sheet = KNO ₃ / m²

7. Culture Conditions of Insect Species Used

7.1 tropical mosquitoes

Place the mosquitoes in cages (48 × 48 × 39 cm) with gauze panels on the sides and leads. The illumination (day / night rhythm) is adjusted with a timer (12 hours of light / 12 hours of darkness) at a temperature of 26 ° C ± 1 ° C and a relative atmospheric humidity of 60% ± 10%. Place cotton wool balls immersed in a 10% concentration glucose solution to allow the mosquito to absorb the fluid. An artificial blood feed is provided twice a week. Bovine blood mixed with anticoagulant is warmed to 40 ° C. using a magnetic stirrer. About 50 ml of this blood is filled into the intestinal length of the pig and then placed in a culture box. In this way, mosquitoes can absorb blood. For spawning, a dish (10 cm in diameter) filled with tap water at a level of 2 cm is placed in the culture box. The deposited eggs are transferred to a plastic dish (25 × 37 cm) filled with 5 liters of demineralized water and placed on a heating pad for terrarium. Mosquito larvae are fed once a day in commercial dry feed for ornamental fish (eg Vita ^® ). After about six days, they reach the pupal stage. To hatch mosquitoes, the pupa with a small amount of water is transferred to a 10 liter plastic bucket. The hatching mosquitoes can then be caught for testing or breeding.

The illumination (day / night rhythm) is adjusted with a timer (12 hours of light / 12 hours of darkness) at a temperature of 26 ° C ± 1 ° C and a relative atmospheric humidity of 60% ± 10%. Place cotton wool balls immersed in a 10% concentration glucose solution to allow the mosquito to absorb the fluid. An artificial blood feed is provided twice a week. Bovine blood mixed with anticoagulant is warmed to 40 ° C. using a magnetic stirrer. About 50 ml of this blood is filled into the intestinal length of the pig and then placed in a culture box. In this way, mosquitoes can absorb blood. For scattering, a 10 cm high filter paper tube is placed in a dish filled with tap water (250 ml) at half its height. After spawning, these tubes are stored in plastic buckets. To prevent the eggs from drying out, the bottom is covered with a wet cellulose layer 3 cm in height in advance. To hatch mosquito larvae, about half of the paper filter stored for two to four weeks in advance is immersed in a plastic dish (25 x 37 cm) filled with 5 liters of demineralized water and placed on a heating pad for terrarium. Mosquito larvae are fed once a day in commercial dry feed for ornamental fish (eg Vita ^® ). After about 4 to 5 days, they reach the pupal stage. To hatch mosquitoes, the pupa with a small amount of water is transferred to a 10 liter plastic bucket. The hatching mosquitoes can then be caught for testing or breeding.
