摘　　要：用石油醚、乙醚、乙酸乙酯3种溶剂对菊苣叶片进行平行提取,以粘虫（Mythimna separate Walker）为供试昆虫,应用饲喂称重法测定菊苣叶片不同溶剂提取物对其生长发育及拒食的影响。结果表明,3种机溶剂提取物处理的幼虫体重均显著低于对照组;从第3~5天,3种有机溶剂提取物处理的幼虫体重之间差异显著,其中乙酸乙酯提取物校正死亡率最高,达52.05%;3种有机溶剂处理的幼虫期比对照延长了4~10 d,且蛹重略高于对照组;3种有机溶剂对粘虫拒食均有显著效果。In order to develop a new plant-source insecticide,some active components from Cichorium intybus L.were extracted with mineral ether,ethyl ether,ethyl acetate,respectively to testify the effects of the components on the development of Mythimna separate Walker and anti-feeding by feeding and weighting method.The results showed that the body weight of the larvae fed by the extracts with organic solvents was significantly lower than the control;the body weight of the larvae fed by the extracts with organic solvents was significantly different in different solvents in 3-5 days.The corrected mortality of the ethyl acetate treatment was the highest（52.05%）,and the development period of the larvae treated by ethyl acetate was about 4-10 days longer than the control and the corresponding pupating rate was the lowest（43.30%）.Therefore,the effect of ethyl acetate extract was most significant.Moreover,the pupa weight of the treatments was little more than the control.The extracts from Cichorium intybus L.leaves had highest bioactivity mainly in anti-feeding activity on Mythimna separate Walker.
