Description

The present invention relates to insect traps, and more particularly to insect traps effective against indoor pests such as in factories and warehouses, but also against outdoor pests. Can be used.

[Prior Art] For example, it is necessary to control insect pests such as tobacco beetles in factories and storage warehouses for tobacco and foods.

Conventionally, an insect trap with an insect attractant has been generally used for such indoor pest control from the viewpoint of safety for humans and livestock.

Moreover, an electric shock killer using an insect attracting lamp is generally used for controlling harmful insects outdoors.

[Problems to be Solved by the Invention]

However, since the conventional insect traps with insect attractants attract insects with a specific odor scattered in the air, the attractive effect is limited to the range in which the odor is scattered.

Therefore, it cannot be expected to have a controlling effect on insects in places where the odor does not reach.

In addition, the range in which the odor reaches may vary depending on factors such as the flow of air, so that the control effect may differ depending on the installation location, and a certain control effect cannot be expected.

On the other hand, an electric shock killer using an insect attracting lamp can attract a large number of insects around the lamp, but controls only insects that collide with the lamp, and the attracting effect and the controlling effect do not match.

In particular, in the case of small insects such as tobacco beetles, the rate of passing through the lamps is high and the rate of collision with the lamps is low, so the control effect is also low.

Even if an insect attractant is attached to an electric shock killer using an insect attractant lamp, there is no suitable attachment point.For example, if the attractant is attached to the lattice, the attractant is attached or detached or the lattice is cleaned. New problems such as time-consuming work will occur.

As described above, none of the conventional insect traps have a sufficient control effect, and an insect trap that exhibits a sufficient control effect has been desired.

[Means for Solving the Problems]

Means for solving the above problems of the present invention are as follows.

That is, the present invention, a lamp for generating insect attracting light, a flat plate-like slide plate to which the insect attractant is attached, and a trapping stand, the slide plate is arranged in the longitudinal direction along the lamp,
It is an insect trap in which the trap is placed below the lamp and the slide plate.

[Action]

According to the insect trap for small insects of the present invention, first, the insect attracting light from the lamp causes small insects in the distance to fly linearly toward the insect trap.

Small insects flying toward the lamp have the habit of passing through the lamp that generates the attractive light, but even if they pass through the lamp, the back wall of the insect trap for small insects is blocked by the wall surface. Land on the wall around the insect trap.

Insects landing on the wall surface around the insect trap for these small insects move toward the slide plate attached with the attractant by walking in response to the action of the attractant, and after reaching the slide plate,
Eventually, it falls from the slide plate to the capture table.

In addition, other insects are attracted by the odor emitted from the attractant and fall when trying to catch on the slide plate, or even if they catch on the slide plate, when they move violently on the slide plate surface in response to the insect attractant. Then, slide your legs and drop them on the trap.

〔Example〕

An embodiment of the insect trap of the present invention will be described below with reference to the drawings.

FIG. 1 is a side view of the insect trap of the present invention, and FIG. 2 is A of FIG.
FIG.

Configuration The insect trap of the present invention comprises a U-shaped lamp 1 that emits insect attracting light, a flat slide plate 3 to which an insect attractant 2 containing an attracting pheromone is attached, and a trapping section made of adhesive paper or the like on the upper surface. And a flat plate-shaped capture table 4 having

The lamp 1 is attached via a socket 6 to a back plate 5 having a surface on which an aluminum vapor deposition film is attached.

The slide plate 3 is arranged vertically along the lamp 1,
It is attached to the upper support member 8 attached to the ceiling 7 via a ring 9.

The sliding plate 3 is made of a transparent material such as vinyl chloride so that both sides are slippery and have a light-transmitting property.

Further, an opening 3a is formed in the lower center of the slide plate 3, and nets 10 are attached to both surfaces of the opening 3a, and the insect attractant 2 is contained between the nets 10.

Although not shown in the drawings, an opening portion in which the insect attractant 2 is housed in a portion of the slide plate 3 that corresponds to the side of the lamp 1.
It is also possible to form a long hole different from 3a.

Further, both surfaces (surfaces) of the slide plate 3 are made of a slippery material and are smooth surfaces, but they may be uneven surface like a corrugated plate, though not shown.

The capture base 4 is attached to the upper support member 8 via a column 11, and is positioned below the lamp 1 and the slide plate 3 in a substantially horizontal state.

In the figure, 12 is a ballast storage box attached to the bottom surface side of the capture base 4, 13 is a switch attached to the ballast storage box 12, and 14 is a roller attached to the back plate 15 side.

Installation site Next, the installation site of the insect trap described above will be described.

The insect trap is installed with the roller 14 in contact with the wall surface so that the lamp 1 is substantially vertical to the wall surface.

When installed in such a state, the sliding plate 3 is also positioned vertically and is positioned substantially perpendicular to the wall surface.

In addition to making the insect trap height close to the ceiling surface, move the roller 14 attached to the side of the trap up and down while keeping it in contact with the wall surface, and install it at a height according to the insect to be captured. You can also

Action Next, the action of the insect trap thus installed will be described.

First, insects gather around by the insect attracting light from the lamp 1.

Some of the insects gathered around the insect trap collide with the slide plate 3 while flying, and fall onto the trap 4, but most of the insects flying toward the periphery of the insect trap are habits. Tries to pass through the lamp 1.

However, since the path is blocked by the wall surface, you will once land on the wall surface around the insect trap for small insects.

When the insects landing on the wall surface around these insect traps for small insects are attracted by the odor emitted from the insect attractant 2 and try to catch on the slide plate 3, or fall on the slide plate 3. Also, when it violently moves on the surface of the slide plate 3 in response to the insect attractant 2, it slides its legs and falls onto the capture table 4.

The insects that have fallen on the capture table 4 stick to adhesive paper or the like and cannot move, and capture is completed.

Test Example In order to investigate the trapping effect of the insect trap of the present invention, the following two types of comparative tests were conducted.

First, in order to investigate the difference in the capture effect depending on the presence or absence of a slide plate, an insect trap equipped with a slide plate on one of the opposite walls of the insect behavior analysis room (3 x 5 x 2.5 m) and a slide plate on the other side. Insect traps with no insects were installed, and the breeding container in which adults were generated was placed in the center, and the number of traps of each trap after a certain period of time was investigated.

This test was performed 4 times (test group 1 to test group 4), and the results are shown in Table 1.

From Table 1, it was confirmed that the insect trap equipped with the sliding plate can capture more insects.

In addition, when the control effect caused by the difference between the slide plate having a smooth surface and the slide plate having an uneven surface is examined,
Sliding plates with uneven surfaces are better.

Secondly, in order to compare the effects of the insect trap of the present invention with a conventional electric shock killing type insect trap, five insect traps are provided in each of the workplaces of two tobacco factories (test zone A, test zone B). They were installed one by one, and the number of insects was investigated about one month later.

The results are shown in Table 2.

From Table 2, it was confirmed that the trap of the present invention can capture more insects than the conventional trap.

〔The invention's effect〕

According to the insect trap for small insects of the present invention, by using the wall surface that is the installation place of the insect trap for small insects, first, by attracting insects from the lamp, the small insects in the distance are placed around the insect trap for small insects. Small insects that have been attracted and attracted to the periphery by the insect attracting light are reliably attracted by the action of the attractant to trap the insects.

Therefore, the insect trap for small insects of the present invention exerts a sufficient control effect.
