PROBLEM TO BE SOLVED: To provide a dish-shaped ambulatory insect capturing device constituted so that tackiness of an adhesive agent is not impaired by discharging water attached to the interior of a bottom plate having an adhesive to the outside in the capturing device of which circumference is surrounded by a side plate.SOLUTION: In the ambulatory insect capturing device in which side plate parts 23 are raised up in standing state from longitudinal end edge of a bottom plate part on which an adhesive 10 is provided and top panel parts engaged with each other by the longitudinal side plate parts 2 and 3 are extended and a rising single board part 11 is provided at left and right end edges of a bottom plate part notch-shaped angular water-discharging parts (b) are installed in four corners of the bottom plate part. Further, notch-shaped central water-discharging parts (a) are installed also in the center in the longitudinal direction in the boundary between the bottom plate part and side plate parts 2 and 3.COPYRIGHT: (C)2007,JPO&INPIT【課題】周囲が側板で囲まれた捕獲器の、粘着剤を有する底板部内に付着した水を外部に排水できるようにして、粘着剤の粘着力が損なわれないようにした皿状の歩行性昆虫捕獲器を提供する。【解決手段】粘着剤10を設けた底板部の前後端縁より起立状に側板部2、3を起立させ、その前後の側板部2,3より相互に係止する天板部を延設すると共に、底板部の左右端縁に立上げ片板部11を有する捕獲器の、底板部の四隅に切欠状の角部水抜部ロを設けた。更に、底板部と側板部2,3との境界における前後方向の中央にも切欠状の中央水抜部イを設けた。【選択図】図1
