主　　题：Cichorium intybus L.leaves Extractions Anti-insect bioactivity Development 

摘      要：In order to develop a new plant-source insecticide,some active components from Cichorium intybus *** extracted with mineral ether,ethyl ether,ethyl acetate,*** were testified the effects of the components on the development of Mythimna separate Walker and anti-feeding by feeding and weighting *** 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 *** 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 ***,the pupa weight of the treatments was little more than the *** extracts from Cichorium intybus *** had highest bioactivity mainly in anti-feeding activity on Mythimna separate Walker.
