JPH0740854B2 - A trap for the peanut - Google Patents

Description

Description: TECHNICAL FIELD The present invention relates to a capture device for the Euphorbiaceae.

Examples of the insects of Astragalus vulgaris include Astragalus serrata, Astragalus serrata, Kashmir Astragalus serrata, and the like are all well known as food pests such as flour.

The insects of Pleurotus cornucopiae are produced in a mill, a food factory,
Present in grocery stores, various warehouses, etc., for example, Kokunusutomoki and Hirata Kokunusutomoku do harm to flour such as wheat flour during storage and are often a problem, as well as dried sweets such as bread and biscuits, ramen , Found in coffee or spices.

[Conventional technology]

Conventionally, there is a trap using an attractant for trapping indoor pests.

As a trap using an attractant, for example, a trap for cockroaches installed on the floor surface, a trap for tobacco beetle, a beetle for jelly beetle installed on a wall surface, and the like are known.

Also, as a catcher for ants, there is one shown in Jitsuko Sho 54-36061.

The ant catcher has a container in which an end portion is bent inward and a screw portion is planted in the vicinity of its center, and a diameter of the container is made smaller than that of the container to directly mix an ant attractant or food. Or an adhesive tray in which these are mixed, and an attaching shaft which is screwed to the screw portion and protrudes downward in the vicinity of the center and has an umbrella-like lid, which can be freely attached and detached. It was formed.

[Problems to be Solved by the Invention]

However, even if the conventional indoor insect pest trap was used with an attractant for the peanut beetle, it was not possible to effectively catch the peanut insect.

That is, none of the catchers for cockroaches is applicable to the insects of the genus Astragalus, which is a small insect.

Moreover, if the trap for tobacco beetle or the beetle for stag beetle is installed on the wall surface as it is, it cannot be applied to insects of Pleurotus cornucopiae that mainly run on the floor.

Even if these traps for tobacco beetles and the like are installed on the floor surface, insects of Pleurotus cornucopia can not be trapped because they repel sticky substances.

Moreover, since the insects of Astragalus terrestris have a property of not advancing to the overhang-like portion and do not get over the end portion of the inwardly bent overhang-like portion and enter the trap, so eventually, No. 54-36061 ant catcher cannot catch the insects of Pleurotus cornucopiae.

Even if a carrier impregnated with an attractant for Astragalus vulgaris is placed in the center of the adhesive-coated paper as it is applied to general pests, this attracts insects of Astragalus vulgaris onto the adhesive surface. I couldn't, and I couldn't catch any of them.

In addition, by utilizing the property that the insects of Astragalus vulgaris prefer a narrow gap etc., we made a trap made of corrugated cardboard and tried to lure this insect through the small hole of the corrugated board and onto the adhesive paper provided in the back. However, although the insect sneaked into the small hole in the cardboard, it could not be caught because it did not approach the attractant on the adhesive paper.

Therefore, there has been a demand for a trap which can effectively trap insects of the genus Astragalus (for example, Astragalus serrata, Astragalus serrata, Kashmir serrata etc.).

[Means for Solving the Problems]

The present inventor observed the walking behavior of the insects of Pleurotus cornucopiae on a flat plate while changing the slope of the flat plate.

As a result, this insect cannot slide freely on a smooth surface, is not good at climbing a vertical surface even with a rough flat plate, and if it is not a smooth surface, slopes up to about 40 degrees Found that they can travel freely, preferentially enter gaps, etc., and have completed the present invention by considering such properties.

That is, the means for solving the problems of the present invention are as follows.

First, a main body having an inclined surface that gradually increases from the peripheral portion toward the center, and a concave trapping portion formed near the top, and an overall umbrella-shaped slope that matches the inclined surface of the main body. It is a capturer of Astragalus chinensis, which has a surface and a lid to which an attractant for Astragalus vulgaris is attached at a position above the catching unit, and the main body and the lid are combined so that there is a gap.

Second, for the first trap, the slope of the inclined surface of the body
It is a capturer for the euglena, which is 10 to 40 degrees.

FIG. 3 shows the first or second catcher for the euglena, which has a gap between the main body and the lid of 2 to 3 mm.

Shape of the main body As for the shape of the main body, it may be a bowl-shaped type having an inclined surface that gradually increases from the peripheral portion toward the center and a concave trap portion is formed near the top, for example, a conical shape, a four-sided shape. Examples include, but are not limited to, a pyramid type, a triangular pyramid type, and a roof type.

It should be noted that a brim-shaped protruding portion that horizontally extends to the floor surface or the like may be provided at the peripheral portion of the main body so that the hem of the body contacts the floor surface or the like without any gap.

Material of Main Body The material of the main body may be, for example, a plastic plate, a cardboard, a cardboard, an aluminum plate, or the like as long as it has a strength capable of maintaining a constant shape.

Inclined surface of the main body The inclined surface has, for example, four surfaces if the shape of the main body is a quadrangular pyramid, two surfaces if it is a roof shape, and one surface if it is a conical shape.

The slope of the inclined surface is usually in the range of 10 to 40 degrees, preferably 20 to 35 degrees, with steep slopes for materials with a rough surface such as cardboard and gentle slopes for slippery materials such as high-quality paper. And

In the case of a particularly slippery material (for example, a plastic plate or an aluminum plate), a surface-roughened surface may be used by scratching the surface or sticking a cloth or the like.

Capturing part The capturing part is formed in a concave shape near the top of the main body so that the trapped insects cannot escape.

When the material of the main body is a rough material, the concave portion of the main body is combined with a catch tray formed of a smooth material having a shape corresponding to the concave portion to form a catch portion.

It is preferable that the material of the catching tray is extremely slippery, for example, plastics such as polyethylene, polypropylene and vinyl chloride, metal plates such as aluminum and copper, and synthetic resin processed cardboard such as silicon and Teflon. Can be used.

To combine the catch tray with the main body, for example, a flange is provided around the upper end side corresponding to the edge of the catch tray, and a step portion that supports the flange is formed on the concave edge on the main body side. Be sure to support the collar.

In this case, the step of the step portion may be equal to the thickness of the collar portion so that the surface of the collar portion and the upper end surface of the inclined surface are as smooth as possible.

When the material of the main body is a smooth material, the vicinity of the top of the main body may be formed in a concave shape and used as it is as the capturing portion.

Further, when the catch tray is used, the vicinity of the top of the main body forms a concave shape in combination with the catch tray, so the bottom surface of the concave portion on the main body side may be open.

Adhesive layer of capture part An adhesive layer is formed on the entire bottom surface of the capture part.

As the adhesive layer, an adhesive used for ordinary insect pest capture may be used, but insects of Pleurotus cornucopiae survive on the adhesive for a long time and run on the adhesive when the adhesive strength is weak. Sometimes you can escape, so to make sure you kill
Each time it is used, it is advisable to directly apply an oily sticky substance or the like to the bottom surface of the capturing part.

Lid The lid has an umbrella shape as a whole and covers the entire body, has an inclined surface that matches the inclined surface of the body, and is an attractant having an attracting effect on the insects of Pleurotus cornucopiae above the catching part. Is attached.

If the lid is made of a transparent material such as transparent plastic, the presence and number of insects in the trap can be confirmed without opening and closing the lid.

Attractant As the attractant, for example, an aggregate pheromone, a disc impregnated with a food attractant, or the like can be used.

The attractant is attached according to the shape of the lid, but it should be located above the center of the capture unit as much as possible.

For example, in the case of a cone-shaped lid, in which the portion corresponding to the upper position of the trap is formed in a flat shape, a disk impregnated with an attractant is attached to the inside of the flat portion. Then, the attractant is attached.

In addition, a cylinder having a cone shape and having an open upper end to be combined with the cap is erected in a chimney shape on a flat portion corresponding to the position above the capturing portion, and a lid having an opening formed on the bottom portion of the cylinder is formed. In this case, the attractant is attached by inserting the attractant which is prevented from falling from the opening and closing the cap.

Combination of main body and lid The main body and lid are combined so that there is a gap of about 2 mm to 3 mm.

For example, on the inclined surface on the main body side, ridges are provided along the inclined direction, or the main body in which protrusions are arranged at regular intervals is used, or inside the inclined surface on the lid side, along the inclined direction. A gap is created by providing a ridge or using a lid in which protrusions are arranged at regular intervals.

[Action]

According to the present invention, the volatile matter from the attractant fills the space between the main body and the lid, then flows down along the slope, and diffuses to the surroundings from the gap between the lid and the main body.

The attractant causes the insects of Pleurotus cornucopiae to gather around the trap and enter the gap between the main body and the lid one after another.

Insects of Pleurotus cornucopiae that have entered the trap are free to run to the left and right, climb up the slope to gradually approach the attractant without issuing an alarm pheromone, and eventually climb up the slope to form a concave shape. Enter the slippery collar on the edge of the capture part of.

Reaching the brim of the edge of the catching part, the insects of the scutellaria japonica approached the inside in order to further approach the attractant, accidentally slipping while walking around the edge, or to other insects. It is pushed and slides into the concave trapping portion, and then the sticky substance cannot trap the trapping portion and is trapped.

Here, when an oily sticky substance is used, the trapped insect can be killed by suffocation by an oil film spread over the entire body surface of the insect without impairing the freedom of running. Therefore, insects can be caught without issuing an alarm pheromone, it can prevent other insects from staying alert and staying away, and since there is no insecticide pesticide used, there is no risk of contamination with pesticides in the vicinity. .

The umbrella-shaped lid not only prevents dust from accumulating inside the main body and allows it to be used in places with heavy dust, but it also keeps the space between the main body and the main body narrow so that the insects In addition to satisfying the conditions as a residence, the volatile components from the attractant are allowed to flow down along the slope of the main body to enhance the attractive force.

Then, during the period of use of the capture device, the insects accumulated in the capture dish can be treated together with the capture dish by replacing the capture dish with a new one. It is economical because the rest can be used as it is.

In addition, if the attractant is attached so that it can be replaced by opening and closing the cap attached to the lid,
Replacing the old attractant with a new attractant makes it possible to maintain the attractive effect.

Are combined so that there is a gap of about 2 mm to 3 mm depending on the height of the ridge 4, and the assembly of the trap is completed.

Action The action of the trap described above will be described.

After the space between the body 1 and the lid 2 is filled with the volatile matter from the attractant 14, the volatile matter flows down along the slope and diffuses from the gap between the body 1 and the lid 2 to the surroundings.

The attractant 14 collects the insects of Pleurotus cornucopiae around the trap, and they successively enter the gap between the main body 1 and the lid 2.

Insects of Pleurotus cornucopiae stuck in the trap climb up the inclined surface 3 in an attempt to approach the attractant 14, and reach the brim 8 of the catch tray 7 corresponding to the edge of the concave catch 6.

The insects of Astragalus vulgaris that have reached the brim portion 8 slipped into the concave catching portion 6 by mistake or while being pushed by other insects while walking along the edge to further approach the attractant 14. However, it is trapped by the oily sticky substance 9 and cannot escape from the trap portion 6.

If the attractive effect of the attractant 14 decreases, open the cap 12, replace it with a new attractant 14, and cap it again.
You can continue the attraction effect by simply closing 12.
