PROBLEM TO BE SOLVED: To provide an insect trap which can shorten the time incapable of trapping insects on the exchange of an attracting source and can improve the efficiency of an attracting source-exchanging work.SOLUTION: The insect trap 10 comprising an attracting means 11 having the first and second light-emitting sources 21, 22 for attracting insects, a support means 18 for supporting an insect-trapping sheet 16 prepared by laminating an adhesive layer 16B to one side of a belt-like substrate sheet 16A at a place close to the attracting means 11 in a state capable of being delivered, and a frame 14 for supporting the attracting means 11 and the support means 18 is characterized in that the second light-emitting source 22 is supported on the frame 14 as a preliminary light-emitting source. The frame 14 has a receiving space 13 capable of receiving the light-emitting sources 21, 22 and an exchange means 33 for guiding the putting-in or out of the light-emitting sources 21, 22 from the receiving space 13.COPYRIGHT: (C)2011,JPO&INPIT【課題】誘引源交換時の捕虫できない時間を短くでき、誘引源交換の作業効率向上を図ることができるようにすること。【解決手段】捕虫器10は、虫を誘引する第1及び第2発光源21、22を有する誘引手段11と、帯状をなす基材シート16Aの一方の面に接着剤層16Bが積層された捕虫シート16を誘引手段11の近傍に繰り出し可能に支持する支持手段18と、誘引手段11と支持手段18とを支持するフレーム14とを備えて構成されている。第2発光源22は、予備としてフレーム14に支持される。フレーム14は、発光源21、22を収容可能な収容空間13と、この収容空間13からの発光源21、22の出し入れを案内する入換手段33とを備えている。【選択図】図2
