Japanese Beetles: Attractancy of Mixtures of Lures Containing Phenethyl Propionate and Eugenol134

Abstract
Traps baited with lures containing equal volumes of phenethyl propionate (PEP), anethole, geraniol, phenethyl butyrate (PEB), and methyl cyclohexanepropionate were mixed with eugenol (30%) and exposed as trinary, quaternary or quinary lures in 2 tests in an area near Wooster, OH, infested with Popillia japonica Newman. Mixtures containing PEP + eugenol + geraniol and PEP + eugenol + geraniol + PEB captured 50% more beetles than the standard lure. Geraniol alone seemed to enhance attractancy since PEB imparted no increase in attractancy when mixed with PEP and eugenol.
