Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to an attractant trap for controlling pests, in particular, Coleoptera flying pests.

<Conventional technology> Among the Coleoptera flying pests, they occur from June to September, and their adults eat roses, sakura, grapes, apples, azaleas, grasses and legumes, and larvae are roots. As a cutworm, beetle beetle (Popillia Japonica), which is a pest of the order Coleoptera, Scarabaeidae, which harms turf roots and humus, is attracting attention. Adult beetles grow on the trees and feed on 1/3 to 2/3 of the leaves, and have the habit of concentrating on weakened trees, so the vigor decreases, the germination and flowering are delayed, and the damage is remarkable In some cases, trees die. In addition, larvae are pests that also affect turfgrass, and in recent years, damage to golf courses has been enormous, and has become a major problem. In other words, larvae directly infest the roots of turfgrass, while adults feed on the surrounding trees, then infiltrate the green and lay eggs.
When it comes to the ground, it damages the soil by depositing it on green.

As a method for controlling the above Coleoptera flying pests, there is a method of spraying pesticides. However, since the method is ineffective against larvae existing in the ground, the pesticides (Sumithion, DDVP , Dipterex, etc.) in such a manner as to come into direct contact with the pests, or a pesticide on trees and leaves that are to be used as food.

However, since such a method requires a large area to be controlled, a large amount of pesticide is applied, which affects natural enemies. There is also a problem that the effect is extremely reduced due to rainfall after spraying.

On the other hand, a method using various traps such as moth lamps, sticky traps, and basin traps has been adopted in order to confirm an appropriate time for pest control. However, this method cannot observe the living body because the pests die after being captured, and also does not allow efficient capture due to the generation of a dead odor.

Therefore, in fact, it is desired to provide a control means that can easily control pests and does not cause environmental pollution by spraying pesticides.

<Problems to be Solved by the Invention> The present invention has been found as a result of intensive studies to solve the problems of the above-mentioned conventional pest control and capture methods. Attract and attract the attracted pests in a specific capture container. That is, by maintaining the ventilation state in the container, the pests can be captured in a living state, thereby preventing the generation of a dead odor. Further, the attractive effect can be enhanced by the sex pheromone released by the captured female, and the capture efficiency is improved.
Therefore, it was found that the application of pesticides was minimized and the environmental pollution was minimized.

<Means for Solving the Problems> That is, the present invention is an attracting and trapping device including an attracting unit for attracting Coleoptera flying pests and a capture container for capturing the attracted pests, wherein the attracting unit is located upward. The capture vessel is located at the top of the capture vessel that opens, and has a small hole for draining rainwater at the bottom of the capture vessel, and an opening having an effective width on the side wall of the capture vessel that does not allow the captured pests to escape. And at least 5 mm above the bottom of the trap.

Hereinafter, the attracting trap of the present invention will be specifically described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of the trap of the present invention, and FIG. 2 is a cross-sectional view taken along the line Χ-Χ ′ of the trap of FIG.

In FIG. 1, the attracting and catching device of the present invention comprises an attracting portion 1 for attracting Coleoptera flying pests, and a capturing container 2 which opens upward to capture the attracted pests. In addition, a plurality of openings 3 having an effective width that does not allow trapped pests to escape are provided on the side wall of the capture container 2 to provide visibility and air permeability inside the container.

In the present invention, the attracting unit 1 is, for example,
No. 1, No. 62-149970, No. 62-149971,
A sex pheromone attractant, a diet, an aroma attractant, etc. of a Coleoptera flying pest are provided on a support plate of any shape disclosed in JP-A-62-149972, JP-A-62-149973, and the like. The sex pheromone attractant is not particularly limited. For example, (R, Z) -5-
Female odorants such as (1-decenyl) -dihydro-2 (3H) -furanone.

The aromatic attractant is not limited as long as it is a odor preferred by Coleoptera flying pests. Lemongrass oil and the like.

Each of the above attractants may be used alone or in combination, and the present invention exerts an effect that the attracted female increases synergistic effect by the sex pheromone released by the pest.

The trapping container 2 constituting the attracting trap of the present invention is open upward, and if the pest attracted to the attracting portion 1 enters the container through the opening 3, the trapping container 2 has a cylindrical, conical or square shape. The shape such as a columnar shape is not particularly limited. An opening 3 having an arbitrary shape such as a circle, an ellipse, or a square is formed on a side wall of the capture container 2.
Are provided. The size of the opening 3 may be any as long as it has an effective width that does not allow the captured pests to escape. Preferably, the effective minimum width (symbol L in FIG. 2) is constant at all openings. Specifically, the angle θ between the container side wall surface and the opening surface at the opening (see FIG. 2),
It is more preferable to provide the opening such that the effective minimum width L of the opening has the following relationship.

L / sinθ = constant value In order to install the trap of the present invention outdoors,
Since rainwater accumulates in the capture container 2 during rainfall, it is necessary to provide a small hole for draining rainwater at the bottom of the container. The opening in the present invention is not such a small hole for draining rainwater, but a plurality of openings are provided at least 5 mm above the bottom of the capture container, and when a small hole for draining rainwater is provided, it is necessary to provide the opening at the bottom. is there.

In addition, as a method of providing an opening in the capture container, the second method is used.
In addition to the arrangement shown in the figure, there is an arrangement shown in FIG. That is, instead of opening the capture container 2 from a fixed direction as shown in FIG. 2, an opening can be provided from the normal direction. In this case, it is easy to provide an opening having a fixed shape.

<Effects of the Invention> As described above, the present invention is an attracting trap including a attracting section and a trapping vessel, and has an opening on the side wall of the trapping vessel. Not
Since the pheromone can be captured while being kept alive, the attractive effect is synergistically improved by the sex pheromone released by the captured pest.

Further, since the number of captured pests can be observed through the opening, the number of pests can be investigated by regularly observing the captured pests. Therefore,
When pesticide spraying is used in combination, it is possible to determine the spraying effect, predict the number of pests generated, and estimate the fate of occurrence.
