14种植物精油对茶尺蠖行为的影响
Effect of 14 Plant Essential Oils on the Behavior of Ectropis obliqua (Prout)
摘要
Abstract
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.关键词
