为获得能够应用于茶园茶尺蠖Ectropis obliqua“推-拉”策略的行为调节剂，在室内测定了茶尺蠖成虫对14种植物精油的趋性反应，及植物精油对茶尺蠖雌虫产卵行为的干扰作用，并采用叶碟法测定了植物精油对茶尺蠖幼虫的拒食作用。结果表明，罗勒、迷迭香、肉桂、茴香及天竺葵5种植物精油对茶尺蠖成虫表现出一定的驱避活性，并且迷迭香油和天竺葵油还能显著干扰雌虫的产卵活动。在3个浓度处理下，茴香、罗勒和藿香植物精油对茶尺蠖3龄幼虫表现出显著的拒食活性。随着精油处理浓度的升高，茶尺蠖幼虫的拒食率升高，生长率随之下降。试验结果证明迷迭香、罗勒、茴香及天竺葵等植物精油对茶尺蠖具有显著的行为调控功能，具备作为茶尺蠖防控剂开发的潜力，值得进一步研究。

To study the repellency, oviposition deterrence and antifeeding effect of 14 plant essential oils against Ectropis obliqua (Prout) and to explore essential oils as the behavior-modifying stimuli of E. obliqua “push-pull”strategy in tea plantations. Behavioral bioassays were conducted to test the repellent and oviposition deterrence activity of 14 different essential oils on adults of E. obliqua, and the antifeeding activities of plant essential oils against the 3rd-instar larvae were investigated by leaf disc choice bioassays. The results showed that Ocimum basilicum oil, Rosmarinus officinalis oil, Cinnamomum zeylanicum oil, Cuminum cyminum oil and Pelargonium graveolens oil displayed strongest repellency against the female and male adults of E. obliqua, and R. officinalis oil and P. graveolens oil also have deterred oviposition for female E. obliqua. Under three tested concentrations of essential oil, C. cyminum oil, O. basilicum oil and Agastache rugosa oil showed strong antifeeding activities to E. obliqua larvae. The antifeedant rates of essential oils increased differently, and the growth rates of E. obliqua larvae decreased with the increase of concentration of essential oils. The results demonstrated that among those 14 plant essential oils, R. officinalis oil, O. basilicum oil, C. cyminum oil and P. graveolens oil showed the remarkable behavior regulating functions on E. obliqua, with the potential to be developed as the components of the ?push-pull?strategy for control of this pest.
