Native and introduced bees were attracted to and captured in commercially available Japanese beetle, Popillia japonica Newman (Coleoptera: Scarabaeidae), traps baited with floral lure components: geraniol, eugenol, and phenethyl propionate [PEP] in Rhode Island, Ohio, and Tennessee. Studies in Rhode Island showed that Bombus impatiens Cresson (Hymenoptera: Apidae) was significantly more attracted to geraniol alone and as a component in floral lure blends than to either eugenol or PEP alone. Xylocopa virginica (L.) (Hymenoptera: Apidae) was more selective in being primarily attracted to traps baited with higher amounts of geraniol in 2016. Removing geraniol from the floral lure blend did not significantly reduce Japanese beetle captures in 2017 and 2018 in Rhode Island and Ohio but did significantly reduce bee captures in Rhode Island in 2017 and 2018. Green, black, brown, and red traps captured significantly fewer bees than clear or standard yellow vane and green cage traps in 2018 in Rhode Island and Tennessee; however, there were no significant differences between Japanese beetle captures in any of the colored or clear traps. Our results show that using all green traps with a lure composed of eugenol and PEP and the Japanese beetle female produced sex pheromone can effectively capture Japanese beetles while minimizing bycatch of bees.
在罗德岛、俄亥俄州和田纳西州，本地蜜蜂和引进蜜蜂被商业上可用的日本丽金龟（Popillia japonica Newman，鞘翅目：金龟科）诱捕器所吸引并捕获，这些诱捕器用花香诱饵成分引诱：香叶醇、丁香酚和苯乙基丙酸酯[PEP]。罗德岛的研究表明，熊蜂（Bombus impatiens Cresson，膜翅目：蜜蜂科）对单独的香叶醇以及作为花香诱饵混合物中的一种成分的吸引力，明显高于对单独的丁香酚或PEP的吸引力。2016年，弗吉尼亚木蜂（Xylocopa virginica (L.)，膜翅目：蜜蜂科）更具选择性，主要被诱饵中香叶醇含量较高的诱捕器所吸引。从花香诱饵混合物中去除香叶醇，在2017年和2018年并没有显著减少罗德岛和俄亥俄州日本丽金龟的捕获量，但在2017年和2018年确实显著减少了罗德岛蜜蜂的捕获量。2018年在罗德岛和田纳西州，绿色、黑色、棕色和红色诱捕器捕获的蜜蜂明显少于透明或标准黄色风向标和绿色笼式诱捕器；然而，在任何有色或透明诱捕器中捕获的日本丽金龟之间没有显著差异。我们的结果表明，使用全绿色诱捕器，搭配由丁香酚和PEP以及日本丽金龟雌性产生的性信息素组成的诱饵，可以有效捕获日本丽金龟，同时将蜜蜂的兼捕量降至最低。
