Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an insect trap, and particularly to an insect trap useful for predicting and controlling the occurrence of pests.

Conventionally, as a pest outbreak prediction and control method, pest attractants such as sex attractants (sex pheromone), aggregation pheromones, and food attractants are used to attract pests, and the attracted pests are attached to adhesive boards, etc. Methods such as killing insects by letting them die, or drowning them in water or a chemical solution in a container, or impregnating insecticides and insect attractants together into a holder, attracting them, and killing them by contact are used. There is.

When using adhesive plates, etc., there are disadvantages in that only the number of insect pests corresponding to the adhesive surface area can be caught and killed, and it is troublesome to replace the adhesive plates and clean up afterwards. When water or a chemical solution is used, it is not only troublesome to clean up afterwards, but also has the drawback of being unsanitary. When using an insecticide-impregnated holder, there is a drawback that the holder must be replaced and cleaned up carefully because it contains insecticidal components. The object of the present invention is to avoid the above-mentioned drawbacks, that is, to be able to capture many insects even if they are attracted at once, by using adhesive, water, chemicals, insecticides, etc.
To provide an insect trap that can trap a large number of insects with relatively few replacements and cause no problems in cleaning up afterwards.

The insect trap of the present invention will be described below in conjunction with the drawings.

As shown in FIG. 1, the first type of insect trap of the present invention includes a deep insect storage bag 1, a top edge of the bag is located in contact with the bag, and the bag is held in an open state; A bag holding hanger 3 having a plane substantially perpendicular to the opening and capable of being hung (e.g. by a string 2), and an insect attractant that can be attached to the bag holding hanger. Holder 4
It is characterized by having the following.

As shown in FIG. 4, the second type of insect trap of the present invention includes a deep insect storage bag 1, a deep insect storage bag 1, a device located above the bag, contacting the bag to hold the bag in an open state, and holding the bag in an open state. It is characterized by having the holding hanging device 3 to which the lower string 2 can be attached, and an insect attractant holder 4 to which the hanging string can be hung.

The bag 1 in the insect trap of the present invention is the upper half thereof. The passage should have a narrowed part such as the neck 5.

This is because the narrow neck section prevents insects that have fallen into the bag from escaping from the bag. The insect trap of the present invention can be used outdoors for a long time.
Therefore, a drainage hole 6 is provided at the bottom of the bag so that water does not accumulate inside the bag even when it rains.

As the above-mentioned bag, a bag made of synthetic resin film is used because it can be slipped even if the captured insects try to climb up, it is water resistant, and it is low in manufacturing cost. In addition, when capturing insects that can tear through the bag, it is preferable to use a particularly thick synthetic resin film for the bag to prevent the bag from being eaten through. The bag holding hanger 3 in the first type of insect trap of the present invention can contact the bag and hold the bag in an open state,
It may have any shape as long as it has a plane substantially perpendicular to the opening and can be hung, for example to which a hanging string 2 can be attached.For example, it can be assembled as shown in FIG. a notch 7 for hanging the bag, a hook-shaped part 8 for hanging the bag, a notch 9 for attaching the hanging string 2, and an insect attractant holder 4.
Two flat plates 11 and 12 having a notch 10 into which can be fitted may be assembled to have a cross-shaped cross section, or may have a notch 7, a hook-shaped portion 8, and a notch 9 as shown in FIG. The flat plate 13 and the piece 14 may be assembled to have a cross-shaped cross section.

Although the bag holding hanger can be made of any material, it is preferably made of synthetic resin, which is easy for insects to slip on, is water resistant, and is inexpensive to manufacture. The color is not particularly limited, but orange to yellow is preferred. The bag holding hanger 3 in the second type of insect trap of the present invention may have any shape as long as it can contact a deep insect storage bag to hold the bag in an open state and to which a hanging string can be attached. Often, for example, as shown in Figure 5,
It may be an annular body having three or more hook-shaped portions 8 around its periphery.

The material may be any material, but it is preferably made of plastic, wire, or the like. The bag is hung on the bag holding/hanging tool 3 by three or more hook-shaped parts 8 provided on the bag holding/hanging tool 3 and three or more corresponding holes provided at the upper end of the bag. It is convenient to do so.

The insect attractant holder 4 in the insect trap of the present invention is a sex attractant 4 (sex pheromone), such as Z, E-9, 11
-tetradecadien-1-ol acetate; Z,E-
9,12-tetradecadien-1-ol acetate;
Z-9-tetradecan-1-ol acetate Z-1
1-tetradecan-1-ol, etc.; aggregate pheromoires, such as ipsenol [(-)-2-methyl-6-methylene-7-octan-4-ol]; ipsidienol [
(+)-2-Methyl-6-methylene-2,7-octadien-4-ol]: E-berbenol [PE)-(+
)-2,6,6-trimethylbicyclo[3,1,1]hept-2-en-4-ol], etc., or food attractants such as eugenol, geraniol, 2-phenylethylene propionate, etc. alone or 2 Any carrier, such as a container, impregnated with or containing more than one species,
It can be felt, cotton, open cell, etc.

In the first type of insect trap of the present invention, the insect 5 attractant holder 4 is attached by fitting a part of the holder into a notch provided in the bag holding hanger 3, or by using an adhesive or an adhesive. It can be attached to the hanging tool 3 using double-sided adhesive tape.

In the second type of insect trap of the present invention, the insect attractant holder 4 may be suspended as it is from a hanging string, or it may be suspended as a flat plate-shaped body carrying or impregnated with an insect attractant. It may be. For example, an insect attractant can be held in a container, felt, cotton, open-celled foam, etc., supported on a flat plate 15, and the flat plate suspended as shown in FIG. 1.4. The insect trap of the present invention is attached to a tree branch, stand, etc. by a hanging string 2, and attracts insects with an insect attractant,
The two attracted insects are placed in the bag holding hanger 3.
After colliding with a plane substantially perpendicular to the opening of the bag, or flying around near the attractant holder 4, a hanging tool or
When trying to stop on the attractant holder or the flat plate holding it, it slips and falls into the bag 1.

These 7 fallen insects escape from the bag and die due to the depth of the bag and, in a preferred embodiment, the presence of a neck. The bag containing dead insects is removed from the bag holding hanger 3, and the bag is disposed of by tying the mouth of the bag. Since the insect trap of the present invention has the above-described configuration, it can achieve the above-mentioned objects.

Next, examples of the present invention will be shown.

Example 1 The insect trap of the present invention having the shape shown in FIG. Using 3F[)-furanone, insects were placed on trees around a golf course in early June, and the number of insects captured by type was investigated one month and two months later.

The results are shown in Table 1. Example 2 Using the insect trap of the present invention as shown in Fig. 4, using eugenol and 2-phenylethylpropionate as insect attractants, it was installed in a petal garden in early June, and one month after installation. After two months, we investigated the number of insects caught by type.

The results are shown in Table 2.
