Forty-one plant essential oils were tested under field conditions for the ability to reduce the attraction of adult Japanese beetles, Popillia japonica Newman (Coleoptera: Scarabaeidae), to attractant-baited or nonbaited traps. Treatments applied to a yellow and green Japanese beetle trap included a nonbaited trap, essential oil alone, a Japanese beetle commercial attractant (phenethyl proprionate:eugenol:geraniol, 3:7:3 by volume) (PEG), and an essential oil plus PEG attractant. Eight of the 41 oils reduced attractiveness of the PEG attractant to the Japanese beetle. When tested singly, wintergreen and peppermint oils were the two most effective essential oils at reducing attractiveness of the PEG attractant by 4.2x and 3.5x, respectively. Anise, bergamont mint, cedarleaf, dalmation sage, tarragon, and wormwood oils also reduced attraction of the Japanese beetle to the PEG attractant. The combination of wintergreen oil with ginger, peppermint, or ginger and citronella oils reduced attractiveness of the PEG attractant by 4.7x to 3.1x. Seventeen of the 41 essential oils also reduced attraction to the nonbaited yellow and green traps, resulting in 2.0x to 11.0x reductions in trap counts relative to nonbaited traps. Camphor, coffee, geranium, grapefruit, elemi, and citronella oils increased attractiveness of nonbaited traps by 2.1x to 7.9x when tested singly, but none were more attractive than the PEG attractant. Results from this study identified several plant essential oils that act as semiochemical disruptants against the Japanese beetle.
在田间条件下，对41种植物精油进行了测试，以评估其降低成年日本丽金龟（Popillia japonica Newman，鞘翅目：金龟科）对诱饵诱捕器或无诱饵诱捕器吸引力的能力。应用于黄绿相间的日本丽金龟诱捕器的处理包括无诱饵诱捕器、单独的精油、一种日本丽金龟商业引诱剂（丙酸苯乙酯：丁香酚：香叶醇，体积比3:7:3）（PEG）以及精油加PEG引诱剂。41种精油中有8种降低了PEG引诱剂对日本丽金龟的吸引力。单独测试时，冬青油和薄荷油是两种最有效的精油，分别使PEG引诱剂的吸引力降低了4.2倍和3.5倍。茴芹油、香柠檬薄荷油、雪松木油、达尔马提亚鼠尾草油、龙蒿油和艾草油也降低了日本丽金龟对PEG引诱剂的吸引力。冬青油与姜油、薄荷油或姜油和香茅油的组合使PEG引诱剂的吸引力降低了4.7倍至3.1倍。41种精油中有17种也降低了对无诱饵黄绿诱捕器的吸引力，与无诱饵诱捕器相比，诱捕数量减少了2.0倍至11.0倍。单独测试时，樟脑油、咖啡油、天竺葵油、葡萄柚油、榄香脂油和香茅油使无诱饵诱捕器的吸引力提高了2.1倍至7.9倍，但没有一种比PEG引诱剂更具吸引力。本研究结果确定了几种可作为日本丽金龟信息素破坏剂的植物精油。
