  As described above, when the generation source estimated by the search device according to the present invention was actually investigated, it was confirmed that flying insects (Aphididae) were generated within the range.

In the present invention, it is necessary to use the same capture device used for the search. In the embodiment, an ultraviolet lamp is used as the attraction source light, and a capture device incorporating an automatic counter is used.
This capture device is intended to capture flying insects, regardless of whether it is an adhesive type, a live capture type, an electric shock type, an insecticidal type, a collection type using a water basin, or the like. In addition, although automatic counting in which an automatic counter is incorporated in the capture device is preferable, visual counting may also be used.

  In addition, when the capture device is placed on the source estimation area line, it is not always necessary to place it directly above the source estimation area line, and it may be installed near the source estimation area line in consideration of surrounding facilities. it can.

It is process drawing which shows the search procedure of the generation source search apparatus of 1st Example. It is process drawing which shows the search procedure of the generation source search apparatus of 2nd Example. It is process drawing which shows the search procedure of the generation source search apparatus of 3rd Example. It is process drawing which shows the search procedure of the generation source search apparatus of 4th Example.
