Mass Trapping for Japanese Beetle (Coleoptera: Scarabaeidae) Suppression in Isolated Areas    (View PDF)

Robert P. Wawrzynski and Mark E. Ascerno

Abstract: Mass trapping to reduce an isolated population of Japanese beetles (Popillia japonica) was investigated. Four years of mass trapping produced a 97% reduction in P. japonica numbers. Although this study lacked strict statistical controls, we feel it shows mass trapping for isolated Japanese beetle populations has merit. Therefore, under certain conditions mass trapping, as part of an integrated pest management program, may be useful for reducing P. japonica populations.
