INSECTICIDE COMPOSITION

Abstract

An insecticide composition including at least one insecticide powder having a melting point above: 75? C., particularly above 100? C., more particularly above 150? C., still more particularly above 200? C., and to be applied on an electrostatic substance. The insecticide composition preferably has at least one insecticide powder being a growth regulator of the benzoylurea group. The electrostatic substance includes a platinum and/or silver complex containing substance. The insecticide composition includes at least one protective powder acting against moisture, in particular silicates, zeolites, silicon dioxide, calcium carbonate and/or diatomaceous earth. The insecticide composition may also include an insect killing fungus.

Claims

1. An insecticide composition comprising: at least one insecticide powder having a melting point above 100? C., and a substance having an electrostatic charge, whereby the at least one insecticide powder is a growth regulator of the benzoylurea group, the insecticide powder having an average particle size between 2 and 20 ?m, for prolonging the effective lifecycle, storage and effectiveness of the insecticide powder.

2. The insecticide composition according to claim 1, wherein the at least one insecticide powder is selected from flufenoxuron (melting point 169-172? C.), and/or triflumuron (melting point 195? C.) and/or diflubenzuron (melting point 228? C.), and/or chlorfluazuron (melting point above 200? C.), and/or novaluron (melting point above 200? C.), and/or hexaflumuron (melting point 203-204? C.).

3. The insecticide composition according to claim 1, wherein the insecticide powder is diflubenzuron.

4. The insecticide composition according to claim 1, wherein the substance having the electrostatic charge comprises a platinum and/or silver complex containing substance.

5. The insecticide composition according to claim 1, wherein in addition the insecticide composition comprises an insect killing fungus, such as fungi of the genera Beauveria and/or Metarhizium and/or Isaria and/or Lagenidium and/or Coelomomyces and/or Culicinomyces and/or Entomophage and/or Nomuraea.

6. The insecticide composition according to claim 1, wherein the insecticide composition comprises at least one protective powder acting against moisture.

7. The insecticide composition according to claim 6, wherein the protective powder has an average particle size between 0.1 and 5 ?m.

8. A structure provided with the insecticide composition according to claim 1, wherein the structure has the form of a gauze, net, cloth, screen, grid, fabric, wall and/or ceiling and/or is made out of concrete, stone, plaster, wood, paper, carton and/or a plastic, whereby on the structure the substance having the electrostatic charge is provided whereon the insecticide powder is provided.

9. The structure according to claim 8, wherein the structure has the form of a gauze, net, cloth, screen, grid, or fabric.

10. The structure according to claim 9, whereby the structure which is made of the plastic is such non conductive that it is capable of holding the electric charge of the substance having the electrostatic charge.

11. The structure according to claim 10, wherein the plastic comprises polyester, polystyrene and/or polyethylene.

12. A pouch holding the structure according to claim 8, wherein the pouch is provided with an electric conducting foil material embodied to electrically shield the structure packaged therein.

13. An exterminator for mosquitos comprising a structure according to claim 8.

14. The exterminator according to claim 13, which comprises a structure in the form of a gauze, net, cloth, screen, grid, or fabric, which is provided with an insecticide powder which is diflubenzuron, in combination with a protective powder acting against moisture, selected from the group of silicates, zeolites, silicon dioxide, calcium carbonate and/or diatomaceous earth, the protective powder having an average particle size between 0.1 and 5 ?m.

Description

[0027] In the drawings:

[0028] FIGS. 1A-1E show perspective views and a sectional view respectively of an exterminator to be provided with a structure according to the invention whereon the insecticide composition according to the invention is provided;

[0029] FIG. 2 shows a pouch according to the invention for holding the structure of FIGS. 1A-1E; and

[0030] FIGS. 3A-3D show views of a possible embodiment of a structure according to the invention for applying the insecticide composition thereon.

[0031] FIGS. 1A-1E show views of a possible embodiment of an exterminator 1 of a type largely similar to an exterminator outlined in WO 2014/007611. In the exterminator 1 an amount of water is present in a largely donut shaped water container 2 present around a central shaft 3 where along a float body 4 is axially movable while floating on the water. A structure 5 is fitted on the float body 4 as shown in FIGS. 3A-3E, while the structure 5 is provided with the insecticide composition outlined hereinbefore. The structure 5 as shown here has the form of a gauze, net, cloth, screen, grid, fabric or some other mesh structure having tube ends 6 to be fitted on piles 7 on the float body 4. In other possible embodiments the structure 5 has the form of a wall and/or ceiling, and/or the structure 5 is made out of concrete, stone, plaster, wood, paper, carton and/or a plastic, whereby on the structure 5 the electrostatic substance is provided whereon the insecticide powder is provided. In general the structure 5 is made of a plastic and/or is such non conductive that it is capable of holding an electric charge of the electrostatic substance mentioned hereinbefore. The plastic may comprise polyester, polystyrene and/or polyethylene.

[0032] FIG. 2 shows a pouch 8 which preferably is provided with an electric conducting foil material 9 for in particular electrically shielding the electrostatic substance and the structure 5 packaged therein. In general the material 7 will comprise a metal.
