Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a trap for insects such as staghorn beetles, which are indoor pests that mainly run on floors.

[Conventional technology]

Conventionally, there are traps using attractants for capturing indoor running pests.

For example, there are traps for cockroaches and tobacco beetles in which an attractant is placed in the center of an adhesive sheet, and insects that approach the attractant are captured by the adhesive sheet.

[Problem to be solved by the invention]

However, insects such as octopus, which have the property of avoiding sticky objects, cannot be effectively captured using traps using adhesive sheets.

Therefore, the applicant of the present application previously proposed the device described in Japanese Patent Application No. 1-224,396 as a trap for insects belonging to the species Octora.

The trap has a main body with a slope that gradually increases from the periphery toward the center, and a concave trap near the top, and an umbrella-like shape as a whole that matches the slope of the main body. It consists of a lid that has an inclined surface and an attractant for small-sized butterflies is attached above the trapping part, and the main body and the lid are combined so that a gap exists.

According to this trap, the insects of the small insect family move up the slope with great force, approach the edge of the smooth trap formed near the top, and eventually the insects on the lower part slide down into the trap. did.

However, the behavior of these insects at the edge of the trap is extremely cautious, and even if they hook their front legs on the edge of the trap, if their footing is unstable, many insects stop moving forward, repeatedly move backward, and then eventually walk away. Ta.

Therefore, although this trap has a considerably superior effect compared to one that simply uses an adhesive sheet for trapping, it is still difficult to say that it has a sufficient trapping effect.

Therefore, there has been a desire for a trap that is more effective in capturing insects such as the white-spotted beetle.

[Means to solve the problem]

As a result of various studies on ways to efficiently capture insects such as the small insects, the present inventor found that insects of the small insect family have short legs and thick claws compared to the body. They found that although they can run freely on smooth surfaces, their legs slip and they are unable to run freely and often roll over, which is why they prefer rough surfaces and, moreover, prefer sloped surfaces.

Furthermore, they discovered that small insects have the ability to move forward in any posture as long as there is a foothold that they can grasp with their front legs, and for example, they will attempt to move forward even on a thin thread.

In this case, as mentioned above, the small insects
They discovered that because their legs are short and their claws are thick compared to their bodies, they are unable to support their large bodies and tend to fall, especially when using thin threads with smooth and slippery surfaces.

The present inventor has completed the present invention based on such knowledge.

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

First, the main body has an inclined surface that gradually becomes higher from the edge to the center, a concave capture part is formed near the top, and a net is provided in the capture part, and a diamond that covers the main body. 6. A combined pest trap 6 Secondly, regarding the first pest trap, the net is made of a slippery material.

Thirdly, regarding the first pest trap, the net has a thread thickness of about 0.05 mm to 0.5 mm, and one side of the mesh is 11 to 10 mm.
It is a pest trap with a size of about m■.

Each part of the trap according to the present invention will be explained below.

The shape of the main body may be as long as it has an inclined surface that gradually increases from the edge toward the center, and a concave capture part is formed near the top, such as a trapezoidal cross section, a conical shape, or a square pyramid shape. , triangular anchor type, etc., but are not limited to these.

For example, when the main body shape is a trapezoidal cross section, the inclined surfaces are composed of two opposing faces, when the main body shape is a quadrangular pyramid shape, it is composed of four faces, and when the main body shape is a conical shape, it is composed of one face.

The slope of the inclined surface is usually about 10 degrees to 40 degrees, preferably about 20 degrees to 35 degrees.

The material may be cardboard with one side smoothed with synthetic resin or the like, a plastic plate, cardboard, an aluminum plate, etc., as long as it has the strength to maintain a certain shape.

Note that the edge portion of the main body may be formed so as to protrude horizontally into a brim shape corresponding to the floor surface, etc., so that the hem of the main body contacts the floor surface etc. without a gap, or A mizusenhari detsuba may be attached to the tsuba.

The trapping portion is a concave portion formed near the top of the main body in combination with the trap or integrally with the trap so that the trapped insects cannot escape.

To combine the trap with the main body, create an opening near the top of the main body, place the trap corresponding to the shape of the opening under the opening, and place a crocodile part around the upper end corresponding to the edge of the trap. A stepped portion supporting the flange may be formed on the concave edge of the main body, and the flange may be supported by the stepped portion.

Note that an adhesive layer may be formed on the bottom surface of the trap.

The adhesive layer may be a sticky material that is normally used for catching insects, but insects of the insect species live on the sticky material for a long time, and when the adhesive strength is weak, they run on the sticky material. In order to be sure to catch and kill them, it is necessary to
It is best to apply an oil-based adhesive directly to the bottom of the trap each time you use it.

The surface material of the net is a slippery material such as nylon, polyethylene, polypropylene, or polyvinyl chloride, preferably polyethylene.

The thickness of the thread is about 0.05 mm to 0.5+us, preferably about 0.2+*+n-0.3+am.

The size of the mesh is approximately 1 anus to IC1++s on the negative side. The size of this mesh is preferably the same as the body length of the insect, or slightly smaller; for example, in the case of insects of the insect class, it is 3.0 mm to 5.0 m+.
It should be about s.

The shape of the mesh may be square, rectangular, rhombus, lattice, or the like, but in the case of insects of the genus Asteroides, the rhombus or lattice shape is preferable.

The net may be attached, for example, by adhering it to the edge of the open part as the trap from the back side, which is the trap side, or it may be attached directly to the surface of the trap.

The lid covers the main body, and an attractant that has an attracting effect on insects of the species Asteroid is attached to the upper center of the trapping part.

Note that if the lid is made of a transparent material such as transparent plastic, the presence or absence and number of insects in the trap can be confirmed without the need to open and close the lid.

As the attractant, for example, a disk impregnated with an aggregation pheromone or a food attractant can be used.

The attractant is attached depending on the shape of the lid, but it should be located above the center of the trap as much as possible.

For example, in the case of a cone-shaped lid in which the part corresponding to the upper part 1 of the trapping part is formed in a flat shape, a disk impregnated with an attractant is pasted on the inside of the flat part. As a result, the attractant will be attached.

In addition, the lid is shaped like a cone and has a chimney-shaped cylinder with an open top that engages with the cap on the planar part corresponding to the upper position of the capture part, and has an opening in the bottom part of the cylinder. In this case, the attractant is installed by putting the attractant in a manner that prevents it from falling through the opening and closing the cap.

For example, in the case of a main body with a trapezoidal cross section, the main body and lid are combined so as to close the open side.

In addition, if the main body is conical, etc., a raised band may be provided on the inclined surface of the main body along the inclination direction, or a main body with protrusions arranged at regular intervals may be used, or the inclined surface of the lid may be on the inside,
By providing a raised band along the inclination direction or by using a lid in which protrusions are arranged at regular intervals, a gap exists between the main body and the lid.

Furthermore, the main body and the lid do not necessarily have to be separate bodies, and may be partially connected via the bottom plate or directly.

[Effect]

According to the trap of the present invention, insects that approach the main body enter between the main body and the lid, climb up the slope of the main body, and some of them fall directly into the trap.

The remaining insects are active around the trapping area, but eventually they try to move forward by getting their feet caught in the net set up in the trapping area.

Most of the insects hang upside down on the net, unable to support themselves, and eventually run out of strength and fall into the trap.

Here, if the tent is made of a slippery material, it is more likely to fall.

Furthermore, when an attractant is attached to the lid, volatile matter from the attractant fills the space between the main body and the lid, flows down along the slope, and diffuses to the surroundings through the gap between the lid and the main body.

Due to the attractant, insects such as small insects gather around the trap and climb up the slope of the main body one after another.

Then, when trying to get closer to the attractant, the insect may accidentally slide down into the concave trapping section due to being pushed by another insect, or it may advance onto the net but then slip into the trapping section.

Here, the lid is used to prevent dust from accumulating inside the main body.
The trap can also be used in areas with heavy dust.

〔Example〕

Hereinafter, one embodiment of the pest trap of the present invention will be described with reference to the drawings.

When the assembly is completed, the attractant 11 is on the net 8! do.

At this time, the distance between the attractant 11 and the net 8 is made as close as possible, and there is no problem even if the two are in contact with each other.

January The action of the trap described above will be explained.

After the volatile matter from the attractant 1PH1 fills the space between the main body 2 and the soba 3, it flows down along the slope 4b, and some of it also flows upward from the notch 10 and diffuses around the trap.

With the attractant 11, the insects of the Phyllidae species,
They gather around the trap and enter the gap between the main body 2 and the lid 3.

The insects of the species Atomidae that have entered the trap climb up the slope 4b in an attempt to get closer to the attractant 11.
Reach horizontal plane 4C.

Some of the small insects that have reached the horizontal surface 4C try to get closer to the attractant 11, or are pushed by other insects, and before they advance onto the net 8, they reach the trap 1 of the trap 6.
fall inside.

In addition, some others are active around the trap 1,
Attempt to advance onto the net 8 provided in the trap 1.

Then, unable to support its body on the net 8, it hangs upside down, and eventually the blade becomes thick and falls into the trap 1.

Objects that have slipped into the trap 1 are captured by the sticky material 9 and cannot be removed from the trap 6.

The pest trap has a simple structure and is easy to assemble for use, and the presence and number of insects in the trap can be checked without removing the lid 3, and the attractant 11 can be easily replaced. can be done.
