This invention offers the composition which includes with the unsaturated aldehyde component and the organic acid component, the said composition, volatilizing, becomes the powerful tokojirami attractant when it is discharged at rather low density. Although as for the particular composition, tokojirami is detected, is watched, and/or induces tokojirami in the specified place which is captured, it is used.< Selective figure >It is not本発明は、不飽和アルデヒド成分と有機酸成分とを含む組成物を提供し、該組成物は、揮発して、かなり低い濃度で放出された場合に強力なトコジラミ誘引物質となる。当該組成物は、トコジラミが検出され、監視され、及び/又は捕獲される所定の場所にトコジラミを誘引するのに用いられる。【選択図】なし
