Behavioral Explanations Underlying The Lack Of Trap Effectiveness For Small-Scale Management Of Japanese Beetles (Coleoptera: Scarabaeidae), Paul V. Switzer, Patrick C. Enstrom, Carissa A. Schoenick

Traps containing a combination floral and synthetic pheromone lure are used to monitor and manage Japanese beetles, Popillia japonica Newman (Coleoptera: Scarabaeidae). One key factor limiting trap effectiveness for beetle control is the "trap spillover" phenomenon, in which the trap attracts beetles without capturing them, resulting in increased damage to surrounding host plants. We investigated the mechanisms underlying trap spillover by conducting two studies in a soybean field in east central Illinois. In the first study, we set up trap stations for 1 d and compared the sex, size, and egg load (for females) of beetles caught in the traps …
