Japanese beetle - Popillia japonica

Traps for monitoring for presence Japanese beetle (Popillia japonica) can also attract nontarget insects such as native bees. A new study shows traps with eugenol and phenethyl propionate—and leaving out geraniol—remain effective in catching Japanese beetles but significantly reduce bee bycatch.
