BACKGROUND OF THE INVENTION
The present invention relates to an insect trap that captures insects such as cockroaches, and more particularly, to an insect trap such as a cockroach that efficiently captures insects by guiding them into a casing by an airflow flowing outward from an opening.
[0002]
[Prior art]
Among harmful insects that inhabit facilities such as houses, warehouses, and buildings, cockroaches are particularly strong insects that have a strong fertility and are difficult to control. Various capture means have been developed in the past to capture and control this cockroach.
[0003]
For capturing cockroaches, many capture containers with poisonous baits and adhesive plates are used. For example, an insecticidal bait (poisonous bait) is disposed at a site formed by a base and a lid attached to the base to form an invading portion into which a pest can enter, and the base and the lid. Insecticidal bait holders (Japanese Patent Application Laid-Open No. 11-4646) have been developed that can prevent the human being from touching human eyes.
[0004]
[Problems to be solved by the invention]
However, with such a capture means, cockroaches cannot be captured efficiently because they do not actively approach poisonous baits or adhesive plates.
To solve this problem, for example, a long tunnel-shaped artificial passage with a poisonous plate placed in the center is used as a wall. A technology provided at a corner or the like (Japanese Utility Model Publication No. 49-2519) has been developed.
[0005]
However, even when such a technique is used, it is difficult to efficiently capture the cockroach because the cockroach cannot be guided into the artificial passage.
This invention is made | formed in view of the said situation, and makes it a subject to provide insect traps, such as a cockroach, which can attract insects, such as a cockroach, in a housing | casing, and can capture them efficiently.

In this trap 1, the flow velocity of the airflow flowing from the opening 3 toward the outside is in the range of 5.6 cm / sec to 20.8 cm / sec.
[0015]
Next, a method for capturing cockroaches using the trap 1 shown in FIG. 1 will be described.
First, the catcher 1 is installed in a place where a cockroach is expected to pass. Cockroaches approaching the periphery of the opening 3 of the trap 1 are attracted to an airflow having a flow rate of 5.6 cm / sec to 20.8 cm / sec flowing from the opening 3 toward the outside, and a temperature of 30 ° C. to 45 ° C. From the opening 3, it passes through the approach path 5 and enters the housing 2 from the housing port 7. Then, the cockroach that has entered the housing 2 comes into contact with the pressure-sensitive adhesive 6 and is trapped.
[0016]
Since such a trap 1 is provided with the airflow generation means 4 which generates the airflow which flows toward the exterior from the opening part 3, a cockroach can be attracted in the housing | casing 2, and a cockroach can be efficiently collected. I can capture it.
Moreover, the effect of attracting cockroaches can be improved by setting the flow velocity of the airflow within the range of 5.6 cm / sec to 20.8 cm / sec.
Furthermore, the effect of attracting cockroaches into the housing 2 can be further improved by maintaining the temperature in the housing 2 within the range of 30 ° C. to 45 ° C.
[0017]
[Example 2]
FIG. 2 is a view showing an example of an insect trap such as a cockroach of the present invention. In FIG. 2, the code | symbol 11 has shown the trap. This trap 11 is provided in two on both sides of the long cylindrical entrance path 15, the casing 12 provided in the center of the entrance path 15, and the casing 12 on the side surface of the entrance path 15. And an airflow generating means 14 for generating an airflow flowing from the opening 13 toward the outside. As with the trap shown in FIG. 1, the airflow generation means 14 is provided with a temperature adjustment function that maintains the temperature in the housing 12 within a range of 30 ° C. to 45 ° C. In addition, the flow velocity of the airflow flowing from the opening 13 toward the outside is in the range of 5.6 cm / sec to 20.8 cm / sec, and the bottom of the housing 12 has the trap shown in FIG. Similarly, an adhesive 16 that captures cockroaches that have entered the housing 12 is applied.

Next, a method for capturing cockroaches using the trap 11 shown in FIG. 2 will be described.
First, the approach path 15 of the trap 11 is installed in a place where it is expected to be a passage of cockroaches. At this time, the approach path 15 of the trap 11 is installed along the wall surface or floor. Cockroaches approaching the periphery of the opening 13 of the trap 11 are attracted to an airflow having a flow rate of 5.6 cm / sec to 20.8 cm / sec flowing from the opening 13 toward the outside, and a temperature of 30 ° C. to 45 ° C. The vehicle enters the housing 12 from the housing port 17 through the entrance path 15 from the opening 13. Then, the cockroach that has entered the housing 12 comes into contact with the adhesive 16 and is caught by adhesion.
[0019]
Since such a trap 11 is provided with the airflow generation means 14 which generates the airflow which flows outside from the opening part 13, it can attract a cockroach in the housing | casing 12, and can capture it efficiently. .
In addition, by setting the airflow velocity within the range of 5.6 cm / sec to 20.8 cm / sec and maintaining the temperature within the casing 12 within the range of 30 ° C. to 45 ° C., cockroaches are placed within the casing 12. The effect of attracting can be further improved.
Furthermore, since it is the trap 11 having the long cylindrical approach path 15, when the approach path 15 is installed along the wall surface or floor, it looks like an electrical wiring mall and is a place where it can be seen by humans. It is difficult to recognize that it is the catcher 11 even if it is installed in the camera, and it can be used without giving an unsanitary impression. Moreover, since the shape of the approach path 15 is a long cylindrical shape, if the position of the opening 13 is set to be close to the cockroach habitat, the housing 12 is located away from the cockroach habitat. Can be installed.
In addition, such a trap 11 has an approach path 15 along a wall surface and the like, and a housing 12 is installed below the wall surface, floor, etc., so that it has a habit of traveling in a corner or a habit of preferring a dark place. Since the cockroach having advancing toward the back of the approach path 15 that is the direction of air flow generation from the opening 13 reaches the housing 12, the cockroach can be captured efficiently.
[0020]
In the trap of the present invention, as in the trap shown in FIG. 2, two openings 13 may be provided on both sides of the housing 12 on the side surface of the approach path 15. Insects such as cockroaches that are distributed in a wide range, with an arbitrary number of openings at multiple locations where the incidence of insects such as cockroaches is high, while extending to match the range where insects such as cockroaches are distributed May be captured with a single trap.
The trap of the present invention may contain an attractant that attracts insects such as cockroaches.
Since such a trap can improve the effect of attracting cockroaches with an attractant, it can be a trap that can capture cockroaches more efficiently.
Furthermore, in the trap of the present invention, as a processing means for processing a cockroach that has entered the housing, a method of capturing using the adhesive 16 can be used as in the above-described example. A method using an insecticide such as contact poison, respiratory poison, or a method such as electric stimulation, heating, cooling, hunger, drying, etc. can be used, and is not particularly limited.
