The flocking dimension s of the brush 83 is set to the same dimension as the inner diameter of the hole 61 on the opening 41 side. A soft bristle material is used for the brush 83, and examples thereof include acrylic fiber, nylon fiber, fluorine fiber, glass fiber, polyethylene fiber, and pig hair.

  The operation of the insect trap 1 configured as described above will be described with reference to FIG. 4 and FIG. 2 described above. FIGS. 4A to 4D show in time series how the insect 2 is captured in the hole 61 of the capturing unit 6 and then discharged from the hole 61. First, as illustrated in FIG. 4A, it is assumed that the discharge unit 8 is in an initial state and the pin 82 is not inserted into the hole 61. When the power of the insect trap 1 is turned on, the light source 3 is turned on and the suction unit 5 starts operation. As shown in FIG. 4B, the insect 2 attracted by the light from the light source 3 and invaded into the outer shell 4 is sucked from the hole 61 by the suction portion 5 and pushed into the narrow portion of the hole 61. As a result, the insect 2 is pinched in a narrow portion by the suction. When the insect 2 captured in the hole 61 increases, the detection unit 7 sends a stop signal to the suction unit 5.

  When the suction unit 5 stops, the drive unit 9 advances the discharge unit 8 to insert the pin 82 through the hole 61 as shown in FIG. The trapped insect 2 is discharged from the hole 61. At the same time, the brush 83 comes into contact with the entire wall surface of the hole 61, and the dirt attached to the hole 61 is removed. With the stop of the suction unit 5, the lid 14 of the insect receiving unit 10 is opened, and the discharged insect 2 falls and is received by the insect receiving unit 10. As shown in FIG. 4D, when the pin 82 is completely inserted into the hole 61, the drive unit 9 moves the discharge unit 8 backward until it reaches an initial state. When the discharge unit 8 returns to the initial state, the suction unit 5 starts operation again. At this time, the lid 14 is closed to prevent the dead body of the insect 2 accommodated in the insect receiving portion 10 from being sucked into the suction portion 5.

  As mentioned above, according to the insect trap 1 which concerns on this embodiment, the insect 2 caught by the hole 61 of the capture part 6 can be removed reliably by the insertion / extraction operation | movement of the discharge part 8, and clogging of the capture part 6 is carried out. Can be prevented. Therefore, in order to maintain the trapping efficiency of the trap 1, there is no need to perform maintenance such as cleaning or replacement of the trap 6. Further, the trapped insect 2 can be pinched by the narrow portion of the hole 61 by the suction of the suction part 5. In addition, compared to a lightning type insect trap that gives an electric shock to an insect, an harsh electric shock sound or the like is not generated, and the insect 2 can be captured quietly. In addition, the insertion / removal operation of the discharge unit 8 can be performed smoothly, and the insects 2 and dirt attached to the hole 61 can be more reliably removed by the brush 83.

In addition, this invention is not restricted to the structure of the said embodiment, A various deformation | transformation is possible in the range which does not change the meaning of invention. For example, in the above-described embodiment, an example in which the light source 3 is used as an insect attracting source has been described. Examples of the odor source include sex pheromones and collective pheromones of insects to be captured, animal and plant extracts to be used as insect foods, and those having an odor similar to these. As the sound source, one that emits a sound including an ultrasonic component such as a flapping sound of an insect can be cited. It is also possible to attract insects by CO ₂ generator.
