PROBLEM TO BE SOLVED: To provide a control agent and method for flying insect pest that enhances the control effect by physically inhibiting the behavior of flying insect pest without using binder or adhesive.SOLUTION: A control agent comprising liquid having a kinematic viscosity of 4 cst or more and having a contact angle of 70° or less as determined by the θ/2 method when the control agent is dripped onto an upper surface of a bee wax layer applied on a horizontal glass plate, is injected toward flying insect pests on flight.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2019,JPO&INPIT【課題】粘着剤や接着剤を使用することなく、飛翔害虫の行動を物理的に阻害して駆除効果を高める。【解決手段】動粘度が4cst以上の液体からなり、水平なガラス板に塗布されたビーワックス層の上面に上記駆除剤を滴下したときにθ/2法で求めた接触角が70゜以下になる駆除剤を、飛翔中の飛翔害虫に向けて噴射する。【選択図】図2
