摘要
【目的】筛选对灰茶尺蠖Ectropis grisescens成虫有引诱或驱避活性的植物性物质,为开发灰茶尺蠖的"推-拉"绿色防治策略提供可选择的基础材料。【方法】利用触角电位(EAG)和Y型嗅觉仪测定灰茶尺蠖雌、雄蛾对土荆芥Chenopodium ambrosioides、留兰香Mentha spicata和黄花蒿Artemisia annua 3种非寄主植物精油的触角电位和行为反应。【结果】灰茶尺蠖雌、雄蛾对土荆芥、留兰香和黄花蒿这3种非寄主植物精油均产生依浓度而变化的触角电位反应,随着精油浓度的升高,触角电位呈现先升高后下降的趋势,最大值分别出现在1,100和100 mg/L浓度下;雄虫对土荆芥和留兰香精油的EAG值大于雌虫,对黄花蒿精油的反应则相反。行为反应测试表明,土荆芥和黄花蒿精油对灰茶尺蠖雌、雄虫定向行为不显著,留兰香精油表现为显著的驱避作用。【结论】灰茶尺蠖对土荆芥、留兰香和黄花蒿这3种非寄主植物精油均产生电生理反应,其中留兰香精油对其具有显著驱避作用。
【Aim】This study aims to screen the chemical attractants and repellents produced by non-host plants,which are potentially used for developing ‘push-pull＇strategy for controlling a common tea pest,Ectropis grisescens. 【Methods】The behavioral and electroantennogram（ EAG） responses of male and female adults of E. grisescens to essential oils from three non-host plants including Chenopodium ambrosioides,Mentha spicata and Artemisia annua were evaluated by using Y-tube olfactometer and EAG. 【Results】Both sexes of E. grisescens adults showed EAG response to the essential oils from C.ambrosioides,M. spicata and A. annua in a dose-dependent manner, with the antennal response strengthening first and then decreasing with the concentration of essential oil,and reaching the maximum at the concentration of 1,100 and 100 mg/L,respectively. Male adults showed slightly greater EAG response than females to the essential oils from C. ambrosioides and M. spicata,while their response tothe essential oil from A. annua was opposite. The results of behavioral response tests showed that both sexes of E. grisescens adults displayed non-significant taxis to the essential oils from C. ambrosioides and A. annua and significantly negative taxis to the essential oil from M. spicata. 【Conclusion】E. grisescens adults show significant EAG responses to the essential oils from the non-host plants C. ambrosioides,M.spicata and A. annua,and the essential oil from M. spicata has repellent activity against E. grisescens.
