It is possible to prevent unpleasant pests from escaping from the capture unit 16 when the suction fan 4 is stopped.

Below, the experimental result which shows the effect of the insect capture apparatus A is described.
[Experiment]
Drosophila capture experiments were carried out using a worm-capturing device with different apparatus conditions under the condition that about 400 Drosophila were released in a 205 × 270 × 250 (cm) dark room. The experiment time was 16 hours from 17:00 to 9:00 the next morning. In addition, each apparatus condition is shown to the following (1)-(4), The other structure which has not been described below is the same as that of the insect capture apparatus A.
(1) The insect capturing apparatus A according to this embodiment was used.
(2) As a light to be installed on the support column 2, a fluorescent lamp was installed in place of the second light 9 which is an insect light that irradiates ultraviolet light. Note that a 10 W light tube was used for both the insect lamp and the fluorescent lamp.
(3) Net 7 was not installed.
(4) As a sheet body to be mounted on the net 7, a white sheet body was mounted instead of the black sheet body 22.

  The following table shows the experimental results related to the experiments (1) to (4).

表１（１）、（２）に示すように、支持柱２に装着するライトとして、誘虫灯である第２のライト９を使用したときと、蛍光灯を使用したときのショウジョウバエの捕獲率はほぼ等しかった。しかし、チョウバエ等、蛍光灯に誘引されない飛翔害虫がいることを考慮すれば、誘虫灯である第２のライト９を使用することが望ましい。

As shown in Tables 1 (1) and (2), the Drosophila capture rate when using the second light 9 which is an insect light as the light attached to the support column 2 and when using the fluorescent light is It was almost equal. However, considering that there are flying pests that are not attracted to fluorescent lamps, such as butterflies, it is desirable to use the second light 9 that is an insect lamp.

  Moreover, as shown in Tables 1 (1) and (3), the capture rate was greatly different between when the net 7 was installed and when it was not installed. When the net 7 was installed, the capture rate was 14% higher than when the net 7 was not installed, and a result that proved the effectiveness of the net 7 could be obtained. Drosophila that stopped on the net 7 during the experiment were confirmed to be attracted by the first light 8 and crawl up to the top of the net 7. By installing this net 7, the suction efficiency can be greatly improved. It could be confirmed.

  In addition, as shown in Tables (1) and (4), when the sheet body 22 to be attached to the net 7 is compared with a black sheet body 22 and a white sheet body, a large difference occurs in the capture rate. I was able to confirm. When the black sheet body 22 is mounted, the capture rate can be improved by 14% compared to the case where the white sheet body is mounted. It was confirmed that Drosophila preferred the light contrast and gathered on the black sheet body 22, and a result that proved the effectiveness of the sheet body 22 was obtained.

  As described above, the insect capturing apparatus according to the present invention mainly targets unpleasant insects that are likely to gather in food such as fly flies, and by providing a net that can stop the unpleasant insects flying near the suction port, particularly Drosophila. It effectively improves the capture efficiency of insects that have the phototaxis but do not have high flying ability.

  Note that the present invention is not limited to the above-described embodiment, and forms in which necessary portions are appropriately changed are also included in the present invention.

It is a perspective view of the insect capturing device concerning this embodiment. It is a section explanatory view of the insect capturing device concerning this embodiment.
