Description

METHOD FOR THE CONTROL OF TERMITES The present invention relates to a method for the control of termites and other social insects and compositions therefor. The use of certain insecticides is known to control social insects such as termites, ants and wasps. Some insecticides, for example insect growth regulators, are used in termite baits to reduce and / or eliminate termite populations. However, a problem that involves the use of such baits with insecticides is that they are based on the randomness of the provision of forage from termites to find the bait and consume it. Certain mixtures of hydrocarbon compounds of alkanes or alkenes comprising from 20 to 40 carbon atoms can stop the movement of certain social and subsocial insects. Compositions comprising said hydrocarbon compounds and insecticides can be effective for controlling termites. The present invention provides a method for the control of termites and other social insects at the site which comprises: (a) providing an attractant composition for termites comprising a mixture of hydrocarbon compounds selected to be alkanes or alkenes comprising from 20 to 40 carbon atoms; (b) providing a thermcide composition; (c) forming at the site a first location treated with the attractant composition for termites in an amount effective to attract termites; and (d) forming at the site a second location treated with an effective amount as a thermistic of the thermicide composition, the second location being close to the first location. That is, the present invention provides a method for the control of termites and other social insects at the site which comprises: (a) treating a first location on the site with an agent composition for attracting termites comprising a mixture of hydrocarbon compounds selected to be alkanes or alkenes comprising from 20 to 40 carbon atoms in an amount effective to attract termites; and (b) treating a second location at the site with an effective amount as a thermide of a thermcide composition, the second location being close to the first location. The term "attract" means the act of directing or inducing termites to the site or location from a point distant from the location or from within the site. Once the termites find the site, the method of the invention also provides for an "arrest" effect whereby the termites thus attracted to the site remain there and are provided with forage or remain near the site. The term "mixture of hydrocarbon compounds" preferably refers to a mixture of hydrocarbons of 23 to 35 carbon atoms, more preferably 25 to 27 carbon atoms. More preferably, the hydrocarbons are selected from the group 11-methyltetracosane, 5-methylpentacosane, 11-methylpentacosane, 9-pentacosene, n-pentacosane, n-hexacosane, 5,17-dimethylpentacosane and 5-methyltetraeosan. In one embodiment of the present invention, either the attractant composition for the termites or the thermcide composition, or both, are sprayed on the soil or, alternatively, they are incorporated into the soil. The thermcide composition is preferably substantially non-repellent for termites and other social insects. In another embodiment, the first location is surrounded by the second location. Either the first location or the second location, or both, may contain a bait for social insects, e.g., a bait for termites. A preferable mixture of hydrocarbon compounds according to the present invention comprises 11-methylpentacosane, (Z) -9-pentacosene, and n-pentacosane (Mixture A).

Another preferable hydrocarbon group comprises 11-methyltetracosane, 5-methylpentacosane, 11-methylpentacosane, 9-pentacosene, n-pentacosane, n-hexacosane, 5,17-dimethylpentacosane and 5-methyltetracosane (Mixture C). A preferable mixture is mixture C-1 which generally comprises 11-methyltetracosane in a proportion comprised between 0.1 and 10% by weight; 5-methylpentacosane in a proportion comprised between 3 and 18% by weight; 11-methylpentacosane in a proportion comprised between 27 and 41% by weight; (Z) -9-pentacosene in a proportion comprised between 11 and 26% by weight; n-pentacosane in a proportion comprised between 19 and 33% by weight; and n-hexacosane in a proportion comprised between 1 and 10% by weight. The mixture C-2 generally comprises from 1 to 5% by weight of 11-methyltetracosane; from 8 to 13% by weight of 5-methylpentacosane; from 32 to 36% by weight of 11-methylpentacosane; from 16 to 21% by weight of 9-pentacosene; from 24 to 28% by weight of n-pentacosane; from 2 to 7% by weight of n-hexacosane; from 0.5 to 3% by weight of 5, 17-dimethylpentacosane; and from 0.5 to 3% by weight of 5-methyltetracosane. In order to make the effects of the mixtures of hydrocarbon compounds according to the present invention meaningful, the amount of mixture to be used can vary according to the species of target insects and the intensity of the intended effect. Preferably, from 0.000001 to 1 g / m2 of the mixture of hydrocarbon compounds according to the invention is used. More preferably 0.00001 to 0.5 g / m2 of the mixture of hydrocarbon compounds according to the present invention will be used. It is even more preferable to use 0.0001 to 0.2 g / m2 of the hydrocarbon mixture according to the present invention. These amounts are equivalent, from a practical point of view, to a quantity of mixture of hydrocarbon compounds according to the invention used comprised between 0.0001 and 100 μg / cm2, preferably of 0.001 to 50 μg / cm2, even more preferably 0.01 to 20 μg / cm2. Generally, alkenes within the class of hydrocarbon compounds of the invention are cis, or (Z) alkenes, e.g., 9- (Z) -pentacosine.

Among the preferred insecticidal compositions according to the invention, the following compositions may be cited as non-limiting examples: fifteen twenty The term "vehicle" refers to an organic or inorganic material that can be natural or synthetic and that is associated with the active ingredient and facilitates its application at the site being treated. Said vehicle is therefore generally inert and must be acceptable from the agricultural point of view, especially in the contemplated or treated site. The vehicle can be solid (clay, silicates, silica, limestone, gypsum, ceramics, resins, wax, fertilizers, etc.) or liquid (water, alcohols, ketones, oily solvents, saturated or unsaturated hydrocarbons, chlorinated hydrocarbons, liquefied petroleum gas , etc.). Among the many additives, the compositions of the invention may comprise surfactants, as well as other ingredients such as dispersants, tackifiers, anti-foam agents, antifreeze agents, colorants, thickeners, adhesives, protective colloids, penetrating agents, stabilizing agents, complexing agents. , anti-flocculating agents, corrosion inhibitors, pigments and polymers. More generally, the compositions of the invention may contain all kinds of solid or liquid additives that are known in the specialty of insecticides and insecticidal treatments. The attraction compositions according to the present invention may contain the mixture of hydrocarbon compounds in very varied proportions depending on the intended efficacy and the target insects. Preferably, the composition according to the invention can contain from 0.000001% to 99.99% by weight of the mixture of hydrocarbon compounds according to the invention, preferably from 0.0001% to 99.99% by weight, more preferably from 0.01 to 99.99% by weight of the mixture of hydrocarbon compounds according to the present invention. The thermcide compositions generally contain the thermofide (s) in effective amounts as thermides, ie, in amounts known to those skilled in the art for their application.

The surfactant may be an ionic or nonionic emulsifier or wetting surfactant. Possible surfactants include salts of polyacrylic or lignosulfonic acids; salts of phenolsulfonic or naphthalenesulfonic acids; polycondensates of ethylene oxide with fatty alcohols or fatty acids or fatty amines or substituted phenols (in particular, alkylphenols or arylphenols); ester salts of sulfosuccinic acids; taurine derivatives such as alkyl taurates; phosphoric esters, or esters of polyoxyethylated alcohols or phenols. When the spray vehicle is water, the use of at least one surfactant is generally required since the active ingredients are not water-soluble. Each of the compositions (a) and (b) can be used in solid or liquid forms. The solid compositions may be powders for pulverization or for dispersion, and granules, especially extruded, agglomerated or compacted granules, or granules which have been obtained by impregnation of a powder. Liquid compositions or compositions which are to be liquid or dispersed in a liquid when applied include solutions, water-soluble concentrates, emulsifiable concentrates, suspensions, suspension concentrates, suspension emulsions, emulsions, wettable powders or pastes or water-dispersible granules. In order to obtain said wettable powders or powders for pulverization, it is appropriate to thoroughly mix the active ingredients and the additives, such as for example by grinding in a mill or similar device. Dispersible granules are generally obtained by agglomeration of a powder, followed by an appropriate granulation process. The emulsions described herein can be of the oil-in-water or water-in-oil type. The Fluidity of the emulsions can range from a low viscosity to a high viscosity that approximates that of the gels. Among the many compositions or formulations, those skilled in the art can select the most appropriate one, according to the specific conditions of the treatment in question. It is possible to use an equal or different form of each of the compositions (a) and (b). In general, compositions (a) and (b) of the present invention are sprayed, soaked, spread, coated or incorporated into the organic soil or cover, in particular in the control of termites and other social insects, eg, ants, cockroaches, worms and locusts. It is preferable that the compositions are substantially non-repellent for the controlled pest species, in particular for ants and / or termites. The method of application of the compositions of the invention is generally to spray a mixture that has been previously prepared, by diluting more concentrated formulations according to the invention. In one embodiment, compositions (a) and (b) are separately formed, mixed and then applied at the site. In this embodiment, composition (a) comprises the attraction agent composition adhered to a substrate that will substantially impede the movement of the attractive agent composition at the site. Examples of the substrate include silica, silica gel, fumed silica, aluminosilicates and salts thereof. For example, when the employ is soil and the compositions are applied in combination, the substrate retains the attractant and in a manner that can be detected by termites and / or social insects. However, the termicide, preferably a water-miscible thermcide, will tend to move downwards, so that a first location and a second location are created according to the invention. That is to say, the termicide is generally mobile in the soil. The term "mobile" refers to the fact that the termicide is not rigidly bound to the soil to the extent that the active ingredient can not be displaced by water from the area in which it was originally placed. For example, the active ingredient as a thermist may have a solubility in water comprised between 100 mg / L and 5000 mg / L at 20 ° C, preferably 200 to 1000 mg / L, most preferably 300 to 600 mg / L. In this embodiment, the termicide generally has an octanol-water coefficient (Koc), as measured under normal conditions, from 20 to 1000, preferably from 100 to 500, preferably from 120 to 250. The therm is generally a DT50 value, which is the dissipation time necessary for half of the initial amount or concentration of the pesticide to dissipate from the site, from 50 days to 1000 days, preferably from 50 to 500 days. Generally, the termicide is stable under gently acidic, neutral and mildly basic conditions, that is, a pH generally of 4 to 10, preferably a pH of 5 to 9. Preferably, the log Pow is 0.1 to 1, 5, preferably from 0.25 to 1.3. The log Pow is the base 10 log of the octanol water partition coefficient that is greater than zero (0) at 20 ° C. The termicide can be an antagonist or agonist of the nicotinergic acetylcholine receptor of an insect. Examples of water-miscible insecticides suitable for the invention include chloronicotinyl insecticides, e.g., imidacloprid, thiamethoxam, clothianidin, or dinitofuran.

Generally, the locations in which each of the compositions is applied are substantially close to each other. For example, the locations are so generally spliced or adjacent to each other or may be offset from each other by a small distance. In a preferred embodiment, the locations of each composition are preferably close enough to one another that the termites attracted by the attractant may also reach the thermcide composition. The locations may be offset from each other by a distance of between about 2 meters and 7 meters, preferably between about 1 meter and 2 meters, more preferably between about 0.1 meter and 1 meter, most preferably from about 5 mm to 50 meters. mm. Generally, it is preferable that the locations are spliced together. When locations are deviated approximately 1 meter or less from each other, a connection member can be used to connect both locations. This member can serve as a guide to direct the tunneling activity of the termites and thus facilitate the movement of the termites between the locations. The member, or connection, may also consist of other suitable surfaces or structures that already exist in the desired treatment site that serve as tactile guides to direct the tunneling activity of the termites and, thus, the movement of the termites between the Connected locations. Examples of members include structures such as load-bearing walls, sidewalks and paving and stone courtyards, structural coatings of the coated or otherwise veneered type, garden bed ridges, wood or cellulose boards, building materials based Styrofoam or urethane foam, utility pipes, cables, wiring, organic roofing beds, irrigation hoses, tree roots and other substantially continuous structures that could serve as a tactile guidance mechanism between adjacent sites of attraction agent for termites and the thermcide composition. The first and / or second site locations may comprise a termite bait. Suitable termite baits include cellulose materials or cellulose derivatives such as wood, cardboard, paper and the like. Materials suitable as baits for termites are known to those skilled in the art. Bait constituents are also contemplated in the compositions of the present invention. Nutritious food stimulants, e.g., fatty acids, amino acids, sugars, carbohydrates, pectins, starches, salts, chitins, plant essential oils and the like are included. The locations of the compositions at the site can be organized in the form of bands substantially close to each other. Generally, it is preferable that the bands be parallel. In another embodiment of the invention, the bands can be crossed or overlapped in discrete locations instead of being applied substantially within the same location. The locations may overlap up to generally less than 50% of the area or width of a single location. In another embodiment of the present invention, the first location may substantially surround the second location or the second location may substantially surround the first location. The locations are close to each other and can be spliced or they can be adjacent to each other or the locations can be deviated from each other by a certain distance. Shapes can be shaped as concentric rings, or as a central location surrounded by an outer location. For example, the attraction agent composition may be sprayed around the termite bait, but not on top of the bait. In another example, you can treat the soil surrounding a termite bait station with the composition of attraction agent. The present invention also provides a device having at least two different faces, one of the faces being treated and / or coated and / or impregnated with an attractant amount for the termites of an attractant composition according to the invention. The second side optionally comprises an effective amount as a thermcide of a thermcide composition. Examples of such devices include flat sheets molded in the proper shape, with a defined thickness; a hollow balloon having an interior surface and an exterior surface, said balloon optionally having a hole that accommodates communication between the interior and exterior surfaces; and a device that is a polyhedron having n faces (or a polyhedron-like shape, such as with non-planar faces and / or rounded corners), one or more of the faces can be treated with the attractive composition and the other treated with a thermal composition. It is possible to treat any of the faces of said devices with both compositions in two different locations on the same face. The present invention also provides a product for the control of termites comprising: (a) a flowable medium containing an attractant amount for termites of a composition as defined above, and (b) a flowable medium containing a thermcide composition; said means being closed within a container but separated from each other by a partition attached to the container under suitable conditions so that the media are separated from each other without contact when they leave for use, and dispensed from the container when they are used (for example, by squeezing), so that the media are close to each other. The composite product can be applied in a location where termites are expected or needed to be controlled. Generally, the media, when used, is forced out into a stream of flowable product and media is but not mixed. Alternatively, the media can be placed for use in two different but adjacent adjacent flow streams. The present invention also provides a product for termite control compound comprising: (a) an attraction agent composition for termites as defined above; (b) a thermcide composition; the attractant composition for the termites and the thermcide composition being enclosed separately or within a water-dispersible or water-soluble material separated from each other and connected by a joint. Generally, the connection is molded or configured from a portion of water-dispersible or water-soluble material. The connection can also be another suitable substance, such as string, rope or filament. The connection may also consist of another suitable substance or structure that serves as a tactile guide to direct the tunneling activity of the termites and, thus, the movement of the termites between connected packages. The use of a biodegradable material may be preferable. The connection can consist of another suitable surface or structure that already exists in the desired treatment location that can serve as a tactile guide to direct the tunneling activity of the termites and, thus, the movement of the termites between the connected applications or packages. . Examples of this include structures such as load-bearing walls, sidewalks and cobblestone and stone courtyards, structural coatings of the coated or other type of plating, garden bed rims, wood or cellulose boards, polystyrene or urethane foam construction materials, service pipes, cables, wiring, organic roofing beds, hoses of irrigation, tree roots and other substantially continuous structures that can serve as a tactile guide connection between separate placements of attraction agent for termites and the thermcide composition. Said water-dispersible or water-soluble materials are described in the European patent publications EP 347222 Al, EP 347221 Al, EP 347220 Al and EP 347119 Al and are generally known to those skilled in the art. Particularly preferable as vinyl polyalcohols are water-dispersible materials. The present invention also provides a product for termite control comprising a thermcide composition, the thermcide composition being enclosed or incorporated in a water-dispersible or water-soluble material as long as the water-dispersible or water-soluble material is not molded to receive and enclose the composition in the form of a pouch or bag. Said bags and bags are described in EP 347222 Al, EP 347221 Al, EP 347220 Al and EP 347119 Al. In a preferred embodiment, the water dispersible material and the thermcide composition are mixed and transformed into a molded article, being distributed the thermcide composition generally uniformly around the article or within the article. For example, a granulated composition of the thermcide can be heated with polyvinyl alcohol and extruded from an apparatus to provide a cord, cord, band or sheet of product of the invention.

In another embodiment, a thermcide composition can be enclosed by two layers or sheets of water dispersible material so that the composition is sandwiched between the layers. The thermcide composition may be in solid (e.g., granulated) or sheet form. For example, a sheet of polyvinyl alcohol can be laminated on one side with the thermcide composition and the layered composition layered with polyvinyl alcohol can be laminated. The edges of the sheet can be sealed or laminated with polyvinyl alcohol thus enclosing the thermcide composition. In the above embodiments, or in another embodiment of the present specification and claims, the attractant composition of the invention can be used with the thermcide composition in combination or separately. If used separately, as in the two previous embodiments, for example, there may be a region of water-dispersible material that separates the thermcide from the attractant compositions. However, the attraction agent composition can be applied separately at the site, close to the thermcide composition. In another embodiment, the thermcide composition and / or the water dispersible material can be designated or molded to provide a release by controlled degradation of the thermcide. In one embodiment, said water dispersible materials are described in European patent publications EP 347222 Al, EP 347221 Al, EP 347220 Al and EP 347119 Al, and are generally known to those skilled in the art.

When the tube is squeezed, the two pastes of the tube are forced through the neck at the same time and they are expelled from the hole in a paste composed of two components whose components remain substantially unmixed.

EXAMPLE 4 A liquid, low-concentration but effective PREMISE 75WP liquid thermal treatment is injected at a depth of 0.3 meters (1 foot) at a distance of 30.5 cm (12 inches), using a normal commercial application equipment, at a reduced but effective application volume against the outer load wall of a structure that was to be protected. In a second, different application, non-toxic bait stakes composed of a compressed solid matrix of cellulose powder mixed with a low concentration of sucrose and a previously applied vertical strip of a surface treatment of 11-methyltetracosane are placed., 5-methylpentacosane, 11-methylpentacosane, z-9-pentacosene, n-pentacosane, n-hexacosane, 5,17-dimethylpentacosane and 5-methyltetracosane in appropriate quantities, in the soil at 0.3 meters (1 foot) from the Injected thermic solution at 0.9 m (3 ft) intervals. A week later, stunned and intoxicated termites emerge from the ground in the vicinity of the bait stakes. Four weeks after spraying no termites are observed in the treatment area.

Example 5 Vinyl alcohol and imidacloprid (in the form of Premise 75 P) are heated and extruded by an appropriate extrusion device to provide a loop of 150 meters (500 feet), 10.16 cm (4 inches) wide and 0 , 2 cm (0.2 inches) thick. The loop is dried. The final analysis shows that the loop provides a dose of approximately 0.5 to 0.9 grams of imidacloprid per 0.3 linear m (linear foot) loop.

Example 6 (A) Preparation of the arrest composition: a mixture of 5-methylpentacosane, 11-methylpentacosane, 9-Z-pentacosene, n-pentacosane and n-hexamethylcosane was diluted at a ratio of approximately 11.4: 36.3 : 19.6: 27.7: 5.0 as a 0.06% (by weight) solution in acetone (0.06 g) in acetone and mixed with 149.4 g of silica brand Zeolex® 7A (JM Huber, Inc. USA). The acetone was removed by evaporation at 50 ° C to 3.5 mm Hg to provide a soft flowable powder. The powder was mixed with 850 g of Premise® 75 P (active ingredient of imidaclorpid) and ground to a consistent appearance. (B) Use of Arrest Composition of Part (A): The final product is distributed on the ground. After several months, the imidacloprid is displaced downwards while the composition of attraction agents remains adhered to the silica gel. The termites are attracted to the mixture of hydrocarbons absorbed with the silica and form a tunnel through the thermicide. EXAMPLE 7 A chain row of polyvinyl alcohol bags, bound by a band of polyvinyl alcohol, is filled in alternately with imidacloprid in the form of Premise 75 WP (Baller CrosScience LP, USA) and the arresting composition of Example 6.

6. 6. The method according to claim 1, wherein the first location further comprises a bait for termites.
7. 7. The method according to claim 1 wherein the second location further comprises a bait for termites.
8. 8. The method according to claim 1, wherein the first location is adjacent to two or more second locations.
9. 9. A method for termite control at a site comprising: (a) providing a attractant composition for termites as defined in claim 1; (b) providing a thermcide composition; (c) forming at the site a first location treated with the composition of the attraction agent for termites in an amount effective to attract the termites and the first location being in the form of a band; and (d) forming at the site a second location treated with an effective amount as a thermide of the thermcide composition, the band of the second location being in the form of a second band near the band of the first location.
10. 10. A method for controlling termites in the place comprising: (a) providing an attraction agent composition for termites as defined in claim 1; (b) providing a thermcide composition; (c) forming at the site a first location treated with the composition of the attraction agent for termites in an amount effective to attract termites; and (d) forming at the site a second location treated with an effective amount as a thermide of the thermcide composition, the second location being substantially around the first location.
11. 11. The method according to claim 10, the first location being in or on the ground.
12. 12. The method according to claim 10, the first location further comprising a tracking and / or control device.
13. 13. A device for attracting or controlling termites or other social insects comprising at least two different faces, treating and / or coating and / or impregnating one of the faces thereof with an attractant amount for termites of an attractant composition for termites, as defined in claim 1, and the other side thereof being treated and / or coated and / or impregnated with an effective amount of a thermcide composition as defined in claim 1, not being treated and / or overcoated and / or impregnating the second different face with an attractant amount for the termites of an attractant composition.
14. 14. A compound termite control product comprising: (a) a flowable medium containing an amount of attraction agent for termites of a composition as defined in claim 1; and (b) a flowable medium containing a thermcide composition as defined in claim 1; said media being enclosed within a container but separated from each other by a partition attached to the container under suitable conditions so that the media is separated from each other, without any contact when they leave for use and are dispensed from the container at the time of use , so that the media are close to each other.
15. 15. A compound termite control product comprising: (a) an attraction agent composition for termites as defined in claim 1; (b) a thermcide composition as defined in claim 1, wherein the composition of the attractant for termites and the thermcide composition are separately enclosed in a water-dispersible or water-soluble material separated from each other and connected by a connection
16. 16. The composite termite control product of claim 15 wherein the connection is formed of a water-dispersible or water-soluble material.
17. 17. A product for the control of termites comprising a thermcide composition, the thermcide composition being enclosed or incorporated in a water-dispersible or water-soluble material, so long as the water-dispersible or water-soluble material is not molded to receive and enclose the composition in the form of a pouch or bag.
18. 18. A product for the control of termites comprising the mixture of a thermcide composition comprising a water-miscible thermcide; and a termite attractant composition, as described in claim 1; the application of the product on the ground; and over a period of time allow the water-miscible thermcide in the thermcide composition to flow out of the soil thus treated to thereby form a first location of a thermcide zone and a second location, an attractant zone for the termites.
