JPS6052724B2 - Insect repellent against Isoptera or Hymenoptera pests - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an insect repellent against pests of the order Isoptera or Hymenoptera.

In the present invention, the insect repellent has a repellent action against the above-mentioned pests,
It means something that has activities such as feeding inhibition and egg-laying inhibition.

Conventionally, insect repellents against Isoptera and Hymenoptera pests include:
Chlorinated insecticides such as chlordesi and deirdrin and compounds such as cresol are used, but their use is being regulated due to safety and persistence concerns.

Therefore, as a result of various searches to develop insect repellents for Isoptera and Hymenoptera pests that are highly safe and practical, the present inventor found that 2-butyl-4-hydroxyanisole and 3-
It was discovered that -butyl-4-hydroxyanisole has a long-lasting insect repellent action against pests of the order Isoptera and Hymenoptera, leading to the completion of the present invention. That is, the present invention is an insect repellent against Isoptera or Hymenoptera pests, which contains one or both of 2-butyl-4-hydroxyanisole and 3-butyl-4-hydroxyanisole.

The target pests of the Isoptera or Hymenoptera of the present invention include termites (e.g., house termites, Japanese termites, etc.);
They are adults (both male and female) and larvae of bees (for example, the black-and-white sawfly, the Japanese sawfly, the soybean sawfly, etc.) and the ants (black carpenter ants, black-bellied carpenter ants, black-spotted ants, etc.). As for the forms used, one or both of 2-butyl-4-hydroxyanisole and 3-butyl-4-hydroxyanisole can be used as is as an insect repellent for Isoptera or Hymenoptera pests. However, it can be dissolved or dispersed in a suitable liquid carrier (e.g. a solvent) or mixed or adsorbed with a suitable solid carrier (e.g. diluent, filler) and, if necessary, an emulsifier or dispersant. , suspending agents, spreading agents, penetrating agents, wetting agents, gelling agents, transpiration accelerators, etc., and any agents such as oils, emulsions, wettable powders, granules, powders, tablets, gels, etc. Can be used in molds. Examples of liquid carriers include water, alcohols (
(e.g., ethanol, ethylene glycol, propylene glycol, benzyl alcohol, etc.), ketones (e.g., acetone, methyl ethyl ketone, diisobutyl ketone, acetophenone, etc.), ethers (e.g.,
Methyl cellosolve, dioxane, dipropylene glycol, organic acid ethylene oxide adduct, polyethylene glycol, etc.), hydrocarbons (e.g. kerosene, kerosene, naphtha, turpentine, etc.), esters (e.g. butyl formate, ethyl acetate, 9 benzoates, 9 phthalates, etc.),
Solvents such as halogenated hydrocarbons (e.g., dichloromethane, dichloroethane, trichloroethane, 1,2-dibromoethane, etc.), coal tar, phenols (e.g., phenol, cresol, xylenol, etc.), monomers for polymer resins are suitable; One or a mixture of two or more of these may be used.

Solid carriers include vegetable powders (for example, soybean flour, wheat flour, wood flour), mineral powders (for example, kaolin, bentonite, acid white +, talcs, silicas), activated carbon,
Cyclodextrins, paper, fibers, plastics, wood, etc. may also be used, and one or a mixture of two or more of these may be used. Further, as the emulsifying agent, spreading agent, penetrating agent, soaps, higher alcohol sulfuric esters, alkyl sulfonates, nonionic surfactants, etc. can be used as necessary. Gelling agents include agar, metal soap, dibenzylidene sorbitol, N-acylamino acid ester,
As the transpiration accelerator, such as N-acylamino acid amide and N-acylamino acid amine salt, known compounds having sublimation properties can be widely used, such as trimers of paradichlorobenzene, dichloromethane, naphthalene, and isobutyraldehyde.

Further, if necessary, glutinous acid, gelatin, starch, alginic acid, polyvinyl alcohol, pine oil, etc. can be added. In addition, the insect repellent of the present invention, synergist, other types of insect repellents, fragrances, pigments, etc. can be appropriately blended.

The insect repellent of the present invention as detailed above can be applied to habitats and places for preventive extermination of Isoptera and Hymenoptera pests. However, by mixing, spraying, applying, or heating and evaporating, pests can be forced to escape from a certain area, or the egg-laying of adults can be inhibited.
By inhibiting the feeding damage of adult insects, etc., damage caused by the above-mentioned pests can be effectively controlled.

The active ingredient of the present invention exhibits an insect repellent effect in a very small amount, so there is no need to be particularly careful about the amount used.
When spraying, apply 0.01m9/ as an active ingredient to the surface.
Clt or higher, or 0.01p as an active ingredient in the air
It is desirable to have it present at a concentration of pm or higher.

This will be explained in detail below using examples.

Example 1 Effect of repelling black carpenter ants Stainless steel pad (length 17n x width 1m x height 20C7) To prevent carpenter ants from escaping, a tangle hood was placed on the upper edge of the stainless steel pad (length 17n x width 1m x height 20C7).
The coating was applied to I width.

Approximately 500 adult male black carpenter ants will be released in the above pad. The upper outer edge of a plywood board (20C7I x 20cm, thickness 2Tn) was treated with 0.5ml of a solution of 10% 3-t-butyl-4-hydroxyanisole, 5% dipropylene glycol, and 85% ethanol, I placed it in the center of the putt. Then, in the center of the plywood board, place a plastic shear plate containing 5% sugar agar (diameter 9CTn x height 1crn).
) was set up. The number of carpenter ants on the agar was investigated on the 1st and 7th day after the treatment. As a result, in the case of the product of the present invention, carpenter ants did not come close to the chale containing sugar agar at all.

On the other hand, in the untreated area, most of the carpenter ants were present on or near the shear glass containing sugar agar.
Example 2 Repellent effect on red ants A 10% ethanol solution of 2-t-butyl-4-hydroxyanisole and 3-t-butyl-4-hydroxyanisole (1:9 mixture) was placed in the vicinity of a large number of red ants nests per square meter. After spraying 10 ml of the solution, no ants were seen near the treatment site.

On the other hand, in untreated areas that were more than 5 meters away from the treated areas, a large number of ants were observed to be active in their nests. Example 3 Repellent effect on house termites Befueromon, which is a guide for house termites, was placed on a filter paper with a diameter of 10 mm.
Apply in a centimeter ring.
