Description

[Detailed description of the invention] (Field of industrial application) The present invention is applicable to insects of the beetle family, such as the beetle beetle, the tobacco beetle, the woolly beetle, the beetle beetle, the beetle beetle, and the beetle beetle.
This relates to a trap for trapping beetles, etc.

All of these insects are extremely omnivorous pests. For example, the beetle eats all kinds of dry plants with a moisture content of 6 to 15%, and is especially often found in stored grains, flour, and confectionery such as bread and biscuits, as well as in various condiments, spices, medicinal herbs, dried fruit, etc. It is considered a problem as a pest of shiitake mushrooms and buckwheat.

In addition, the beetle is a pest of books and has become a problem in preserving old books in libraries and the like.

The object of the present invention is to provide a trap that can be used in conjunction with the control of grasshopper insects using an attractant.

(Prior art and its problems) As a device for trapping indoor pests using attractants, many insect traps mainly targeting cockroaches are known (for example, Utility Model Publication No. 52-1807, 52−
No. 11094). However, none of these methods apply to small insects such as the beetles.

Also, a trap for tobacco beetles (1983-
25822) could not be said to have a high ability to capture this insect, and was not fully satisfactory as a trap for grasshopper insects.

(Means for solving the problem) The present inventor places a carrier impregnated with an attractant in the center of a mount coated with an adhesive, as is applied to general insect pests, and uses this to attract insect pests. As a result of trying a method of luring and capturing insects onto a sticky surface, it became clear that these insects recognize viscous substances and strongly avoid them, so they are not captured by the sticky surface.

In addition, even when an attractant was mixed with the adhesive and applied, or when a sex pheromone with the strongest attracting effect was used, it was not possible to attract the animals to the adhesive surface.

In the end, it is impossible to capture grasshopper insects by using a combination of an attractant and an adhesive surface, and capturing the insects themselves when they actively step onto the adhesive surface. It became clear.

Therefore, the inventor of the present invention observed the walking behavior of insects of the insect class such as the zebra beetle on a smooth surface coated with substrates with different physical properties under the combined use of an attractant, and based on this observation, various types of trapping were carried out. As a result of prototyping the container and conducting repeated studies, we found that although insects of the insect family have a strong aversion to stepping on sticky surfaces, they have no resistance at all to walking on smooth, slippery surfaces. , the insects that reacted to the attractant slide down while actively moving on the smooth surface of the inner wall of the trap and are captured by the adhesive layer provided at the bottom, and the attractant is placed on the smooth surface. As a result, the grass beetles are able to reach the attractant, but because they are unable to engage in mating behavior, they repeatedly run abnormally (quick zigzag runs), and most of the insects fall off and are caught and killed by the sticky layer. By placing an attractant on a smooth surface, grasshopper insects can reach the attractant, but because they are unable to engage in mating behavior, they run abnormally (quick zigzag motion) and most of the insects fall off. The insects are captured and killed by the sticky layer, and this method of capture is more effective than expected, as most of the insects that reach the trap are captured, leading to the completion of this invention.

That is, the present invention provides a pest trap comprising a container body with an opening, an adhesive surface, an attractant, and a smooth surface, in which the container body has a box-like shape suitable for installation on a vertical surface such as a wall, To provide an insect trap for grass beetles, characterized in that a smooth surface part is provided inside the container body, an attractant is attached to the middle of the smooth surface part, and an adhesive surface is further provided at the lower part of the inner surface of the container body. It is.

(Function) The attractant used in the trap of the present invention has the effect of gathering grasshopper insects in one place and increasing the chances of the insects coming into contact with each other and sliding down. The smooth surface has the effect of increasing the chances of insects sliding down, either alone or in combination with the attractant.

The adhesive surface of the trap of the present invention is primarily used to prevent insects from slipping from the vicinity of the attractant, rather than to directly capture invading insects as in cockroach traps.

Furthermore, as shown in Examples below, forming a corner near the attractant is also effective in creating an opportunity for the attractant to fall.

Furthermore, it is effective to shorten the distance of the attractant from the opening because it can enhance the effect of the attractant on insects attached to the container.

(Example) Embodiments will be described below with reference to drawings showing examples.

1 is the container body. The shape of the container body 1 may be any box shape, such as a rectangular parallelepiped or a triangular prism, but it is suitable for insects of the insect class 2 to 6 inches long.
Since the size is extremely small, on the order of mm, it is preferable to have a shape that is easy to attach so as to make contact with a wall surface, etc. The material of the container body 1 may be any material, such as plastic sheet, cardboard, cardboard, etc., as long as it has the strength to maintain a certain shape. Although the depth of the container body 1 depends on its size, it is usually preferably about 10 to 50 mm.

2 is an opening. The container body 1 is provided with an opening at least at one location. The opening 2 serves as an entrance for trapping insects, and at the same time serves as a dispersion port for the attractant. The openings 2 are usually provided on the left and right sides when the trap of the present invention is attached to a wall or the like.

4 is a smooth surface portion. The smooth surface portion 4 is formed inside the container body 1. The smooth surface portion 4 is formed of a smooth surface formed on the inner surface of the container body 1. If the material of the smooth surface part 4 is extremely slippery, the insects of the insect species will not reach the attractant and will mainly slide down near the periphery of the surface part 4; if the material is not slippery, most of the insects of the insect species They reach the vicinity of the attractant and slide down due to contact between insects. Therefore, the material of the smooth surface portion 4 should be selected appropriately taking into account the ecology of the insects of the insect species,
For example, silicon, Teflon, nylon, acrylic, and vinyl chloride films, or metal foil plates made of aluminum or the like are used.

5 is an attractant. The attractant 5 is usually attached to the middle of the smooth surface portion 4. As the attractant 5, for example, a disk impregnated with a sex pheromone or a food attractant is used. Regarding the position of the attractant 5, it is preferable that the distance from the opening is as small as possible in terms of the attracting effect, but in order to increase the number of insects that slide down before reaching the attractant 5, it is preferable to position the attractant 5 away from the periphery of the smooth surface part 4. .

Further, 6 is an adhesive surface. The adhesive surface 6 is the lower inner surface of the container body 1, that is, the smooth surface portion 4 and the attractant 5.
Established at and around the landing point of insects that have fallen from the ground. The adhesive surface 6 is usually prepared by separately applying an adhesive used for trapping pests to a mount and pasting a release paper on it, and then attaching it to the relevant area or attaching it removably, and then using it. It is formed by peeling off the release paper or applying it directly to the lower part of the inner surface each time it is used.

16b is integrally provided, and openings 2 are formed on the left and right sides of the side plates surrounded by the top plate 7, the bottom plate 9, and the side plates 8a and 8b. 6 is an adhesive surface, and 5 is a beetle attractant. Side plates 8a and 8b arranged in parallel
The selection of the interval may be determined according to the degree of dust production at the place of use. The reason why the top plate 7 is inclined is to prevent dust from accumulating on the top plate. In addition, by making the upper part of the side plate 8a narrower than the lower part, the attractant 5 can be removed from the wall side end of the opening 2.
The distance can be reduced and the effectiveness of the attractant can be increased.

FIG. 4 shows a second embodiment, and is a perspective view thereof. The structure of this trap is basically
Although FIG. 3 is similar to the one described above, it is a simpler ready-made type, whereas FIGS. 1 to 3 are of an assembled type.

FIG. 5 shows a third embodiment, and is a perspective view thereof. The structure of this trap is basically the same as that explained in FIG. 1, but the trapping rate is increased by providing an uneven portion 16 on a part of the smooth surface. There is no difference in the capture rate whether the unevenness is acute or obtuse, but the lowest amplitude is 5 mm.
It is preferable to set it as above.

FIG. 4 shows a fourth embodiment, and is a perspective view thereof. The shape of the trap is basically the same as that explained in FIGS. 1 to 3 except that the shape of the trap is a triangular prism, but a small opening 2 is provided in the upper part of the side plate 8b at a position facing the attractant 5. The difference is that Of the three openings 2, many of the insects of the insect family slipped down from the central opening closest to the attractant 5. Third
Similar to the uneven portion in the embodiment, by gathering insects of the insect class near the attractant 5, the chances of the insects sliding down can be increased.

(Effects of the invention) As explained in detail above, the insect trap for grass beetles of the invention has a simple structure, is suitable for mass production, and is easy to assemble for use.
Since it has excellent attracting and trapping effects on insects of the insect species, it can be widely used in food factories, grocery stores, various warehouses, etc., with great effects.
