Minimizing bee bycatch in Japanese beetle traps

Native and managed bees were attracted to and captured in commercially available Japanese beetle traps baited with floral lure components containing geraniol, eugenol, and phenethyl propionate. We found that removing geraniol from the floral lure blend did not significantly reduce Japanese beetle captures in 2017 and 2018 but did significantly reduce bee captures in Rhode Island. Our results show that using all green traps with a lure composed of eugenol and the Japanese beetle female produced sex pheromone can effectively capture Japanese beetles while minimizing bycatch of bees.
