title: Japanese beetle (Coleoptera: Scarabaeidae) : Response to synthetic sex attractant plus phenethyl propionate: Eugenol.
abstract: A combination of the synthetic sex attractant (R,Z)-5-(1-decenyl) dihydro-2(3H)-furanone with a 3∶7 mixture of phenethyl propionate (PEP) and eugenol (4-allyl-2-methoxphenol) caught significantly morePopillia japonica Newman than either the sex attractant or the mixture did alone. Also, the synthetic sex attractant captured significantly more males than the PEP-eugenol did during the period of heavy adult emergence of the beetles. The two lures were not significantly different in their attractancy to males about a week later and thereafter. A combination of PEP-eugenol and virgin females in the same trap late in the season also significantly increased beetle captures.
