JPH11217305A - Attractant for files - Google Patents

Abstract

PROBLEM TO BE SOLVED: To obtain an attractant useful in extermination of files by making the attractant include a phenylacetic ester as an active ingredient. SOLUTION: This attractant is obtained by including a phenylacetic ester selected from among e.g. methyl phenylacetate of formula I, ethyl phenylacetate of formula II, propyl phenylacetate of formula III or phenetyl phenylacetate as an active ingredient. As the above attractant, the phenylacetic ester is used as it is or after being made a preparation of it. The making a preparation of it can be carried out by, at need, preparing the solution dissolved into an organic solvent, e.g. dichloromethane or the like, and allowing a suitable carrier (e.g. a polyethylene, a glass fiber or the like) to adsorb it. The above attractant possesses more potent attraction effect than that of (Z)-9-tricosene known as a sex pheromone of files and is useful in the extermination of files.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD OF THE INVENTION

[0002] The present invention relates to an attractant for diptera flies.

[0003]

[Prior art]

[0004] Fly flies occur in cattle stalls, poultry houses, garbage disposal sites, and the like, and cause great damage as sanitary insects and unpleasant insects to the workplace or nearby residents, and thus need to be eliminated.

[0005] In general, insecticides are used to control flies. However, controlling flies with insecticides is not sufficient as a means for preventing damage by flies.

[0006] Therefore, there has been proposed an extermination means using an attractant. For example, a fly is attracted with a bait obtained by adding an insecticide to the attractant, or a fly catcher is used after attracting the fly. Means of killing by the mechanical method described above have been proposed.

Conventionally, as a fly attractant, for example,
It is known to use a sex pheromone such as (Z) -9-trichocene as an active ingredient.

[0008]

[Problems to be solved by the invention]

However, the attractant containing (Z) -9-tricosene as an active ingredient has insufficient attracting action against flies and is not satisfactory for use in controlling flies.

[0010] Accordingly, the present invention provides an attractant which has a stronger attracting effect than (Z) -9-trichocene, which is known as a sex pheromone of flies, and is satisfactory for use in combating flies. The purpose is to:

[0011]

[Means for Solving the Problems]

The present inventors have conducted intensive studies to solve the problems of the present invention. As a result, they have found that a specific phenylacetate ester has a strong attraction effect and a behavior stimulating effect on flies. It was completed.

That is, the fly attractant of the present invention contains phenylacetate as an active ingredient, and is particularly selected from the group consisting of methyl phenylacetate, ethyl phenylacetate, propylacetate, and phenethylacetate. At least one ester compound as an active ingredient.

Further, the fly attractant of the present invention comprises, as an active ingredient, a mixture of at least one ester compound selected from the group consisting of methyl phenylacetate, ethyl phenylacetate, propylacetate, and phenethyl phenylacetate. Is what you do.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, the fly attractant of the present invention will be described in more detail.

The fly attractant of the present invention contains at least one of phenylacetate as an active ingredient, particularly at least one of methyl phenylacetate, ethyl phenylacetate, propyl phenylacetate and phenethyl acetate. I do.

These phenylacetic esters are represented by the following chemical structural formulas, and are known compounds per se.

As the fly attractant of the present invention, the above-mentioned phenylacetate may be used as it is, or may be used after being formulated.

Formulation is carried out by a method known per se, for example, by adsorbing the active ingredient of the attractant of the present invention as it is or, if necessary, as a solution in an organic solvent such as dichloromethane or the like to a suitable carrier. Can be performed.

The material and form of the carrier are not particularly limited. For example, pellets, fibers or films of a polymer such as plastic or rubber such as polyethylene can be used, and inorganic materials such as glass fiber can be used. You can also.

When the attractant of the present invention is used, there is no particular limitation on the storage of the attractant. For example, a capsule made of plastic from which the active ingredient can be released, or the active ingredient can be stored by utilizing the capillary action. Any that can be released can be used.

The extermination of flies using the attractant of the present invention is carried out by using a trap provided with the attractant stored therein and effectively attracting and capturing the flies with the trap. Can be.
