PROBLEM TO BE SOLVED: To provide a pest insect trap which can maintain the capture performance of pest insects by an adhesive sheet over a long period of time when used in a farm requiring capturing of pest insects, particularly, an agricultural field in which soil dust, sand dust, litter or the like flies due to air flows, and is excellent in usability.SOLUTION: The pest insect trap includes: a bar-like strut portion 1 fixed in an installation place a holding portion 2 having a columnar body 21 and an intermediate hole 22 formed to extend from the lower end to a predetermined intermediate position along the center line of the body, the holding portion being rotatably and detachably supported by a tip of the strut portion 1 inserted to the intermediate hole 22 on a ceiling wall 22a of the intermediate hole 22 an adhesive sheet portion 3 having a substrate 31 and an adhesive layer 32 formed on the substrate 31, the sheet portion capturing attracted pest insects by the adhesive layer and an attachment portion 4 for attaching the adhesive sheet portion 3 to the holding portion 2 along the center line direction of the body 21 of the holding portion 2. The installation position of the adhesive sheet portion 3 can be changed in a direction parallel to a direction of air flow by rotating the adhesive sheet portion 3 around the strut portion 1.COPYRIGHT: (C)2013,JPO&INPIT【課題】害虫を捕獲する必要のある農場、特に、気流によって土埃、砂埃、ゴミ等の舞い上がる圃場において用いた場合、長期に渡って粘着シートによる害虫の捕獲性能を維持することが可能で、使い勝手に優れる害虫捕獲器を提供する。【解決手段】設置場所に固定される棒状の支柱部1と、柱状の本体21と、本体の中心線に沿って下端から所定の中間位置まで貫通して形成された中間穴22とを有し、中間穴22に挿入された支柱部1の先端によって、中間穴22の天井壁22aにおいて回転及び着脱可能に支持される保持部2と、基材31と、基材31上に形成された粘着剤層32とを有し、誘引した害虫を粘の剤層で捕獲する粘着シート部3と、保持部2の本体21の中心線方向に沿って、粘着シート部3を保持部2に取付ける取付部4と、を備え、粘着シート部3が支柱部1を中心として回転し、気流の方向に平行な方向にその設置位置を変えることが可能な構成とする。【選択図】図1
