Description

[Detailed description of the invention] <Industrial application field> This invention relates to an insect trap for flying pests belonging to the so-called Coleoptera order, such as Scarabidae and Cerambycidae.

<Prior art> Generally, as a method of capturing flying pests belonging to the order Coleoptera in forests, orchards, golf courses, etc., the pests are attracted using an attractant such as eugenol or geraniol, and then captured in an insect trap. things are being done.

As an insect trap used for such trapping, for example, as shown in Japanese Utility Model Application No. 58-192581, a prefabricated Yagura for supporting an attractant container is removably attached to the outlet of the insect trap, and the attractant container is fitted into the Yagura. There is something to wear.

<Problems that the invention seeks to solve> However, since the insect traps described above have open-ended Yagura, a considerable portion of the pests that are attracted to the Yagura cannot be trapped inside the insect trap and escape. There is a problem.

This invention was made in order to solve the above-mentioned problems, and aims to provide an insect trap that can efficiently attract pests belonging to the order Coleoptera and trap them in the insect trap.

<Means for Solving the Problems> In order to solve the above problems, this invention includes a conical member with a large diameter at the bottom, an insect trap with an opening on the top, and an insect trap at the bottom of the conical member. The conical member is hollow and contains an attractant therein, and has a uniform width between its lower periphery and the inner circumferential surface of the insect trap container. It has an opening formed therein.

<Function> When a flying insect of the order Coleoptera lands on the outer circumferential surface of the conical member and works, since the outer circumferential surface of the conical member is sloped, it slides down into the insect trap placed at the bottom.
Captured in an insect trap.

<Example> Hereinafter, an example of this invention will be described based on the attached drawings.

As shown in the figure, the insect trap includes a conical member 1 with a large diameter at the bottom, an insect trap 2 disposed at the bottom of the conical member 1, and a fixture 3 for attaching the insect trap 2 to the bottom of the conical member 1. It is made up of.

The conical member 1 has a conical or pyramidal shape, and is made of polyethylene or polypropylene, which is a material with excellent weather resistance and has the strength to fix a hanging jig 4, such as a round screw, to the top thereof. It is formed by injection molding or the like.

The conical member 1 is formed into a hollow interior with an open bottom, and an attractant 5 is attached to an appropriate position inside the conical member 1, for example, on the inner wall surface of the top portion, using an adhesive or an adhesive tape.

In order to efficiently diffuse the attractant 5, arbitrary diffusion holes may be provided in the top wall surface of the conical member 1.

The insect trap container 2 is made of a synthetic resin bag, a waterproof paper bag, or the like, and is sized so that the upper opening loosely fits into the lower end of the conical member 1. A punch hole 6 is provided.

The fixtures 3 are installed at a plurality of locations on the lower outer periphery of the conical member 1, and are attached by clamping or hooking the upper end of the insect trap container 2. The width of the opening 7 formed between the opening 7 and the inner peripheral surface of the container 2 can be adjusted.

The width of the opening 7 is determined from the outer peripheral surface of the conical member 1 to the insect trap container 2 according to the size of the pest to be captured.
The opening width is set so that pests can easily fall into the conical member 1, and the width of the opening is approximately uniform throughout the circumference of the conical member 1.

In order to capture pests more efficiently, as shown in FIG. Insects flying to land may be captured in the insect trap 2 by colliding with the shielding plate 8.

The insect trap of this invention has the above structure,
A hanging jig 4 is used to suspend the flying pest at the trapping site, and the flying pest is made to land on the outer peripheral surface of the conical member 1.

Since the conical member 1 has an inclined surface, the pests that land on the insect trap slide down the inclined surface, fall into the insect trap container 2 through the opening 7, and are captured.

<Effects> As described above, according to this invention, the insect trap is attached to the lower part of the conical member via the fitting, and an opening of uniform width is created between the outer circumference of the lower end of the conical member and the inner circumferential surface of the insect trap. With this structure, the insect pests attracted to the outer periphery of the conical member can be trapped by sliding down into the insect trap container on the inclined surface, and the pest trapping effect is greatly improved.
