PROBLEM TO BE SOLVED: To provide a device for capturing flying insects by which flying insects such as flies and bees can be well attracted and captured.SOLUTION: The device for capturing flying insects comprises a lower vessel 1 having an outer circumferential wall 12 directing in vertical direction along the whole circumference of the side face, and an upper cover 2 having an opened bottom and attached to the upper part of the lower vessel 1 in a manner to cover the upper part of the lower vessel 1. A horizontal gap S is formed between the upper outer side of the outer circumferential wall 12 of the lower vessel 1 and the lower inner side of the upper cover 2, and the gap S formed between the lower vessel 1 and the upper cover 2 is used as an invasion port 3 to allow the entering of the flying insects into the vessel.COPYRIGHT: (C)2009,JPO&INPIT【課題】ハエやハチ等の飛翔昆虫類を良好に誘引し捕獲することができる飛翔昆虫類捕獲器を提供する。【解決手段】側面全周にわたって縦方向に向かう外周壁12を備える下部容器1と、この下部容器1の上部に下部容器1の上方を覆うように取り付ける下部を開口する上部カバー2と、からなり、下部容器1における外周壁12の上部外側と上部カバー2における下部内側との間において水平方向の間隙Sを形成し、この下部容器1と上部カバー2との間に形成した間隙Sを、飛翔昆虫類が内部に侵入するための侵入口3とした飛翔昆虫類捕獲器である。【選択図】図3
