摘要
采用皿内测定法,研究了土荆芥精油对灰茶尺蠖的熏蒸活性及对其体内2种解毒酶活性的影响。结果表明,随着土荆芥精油剂量的增加和处理时间的延长,灰茶尺蠖幼虫的死亡率也相应升高;LC_(50)随着处理时间的延长,逐渐降低;通过测定土荆芥精油对灰茶尺蠖幼虫体内解毒酶活力变化表明,其精油对灰茶尺蠖幼虫体内的乙酰胆碱酯酶呈明显的抑制作用,对羧酸酯酶呈激活后抑制的作用。
Fumigant activity of Chenopodium ambrosioi des essential oil and it’s effect on two enzymes of Ectropis grisescens were studied. Corrected mortality of E. grisescens larvae showed dose-and time-dependent increases with C.ambrosioides essential oil treatment. The LC50 decreased gradually with increment of treatment time. The oil showed inhibition effect on acetylcholinesterase, and showed inhibition effect after activation on carboxylesterase in E. grisescens.
