Abstract:: Seed，fruit and stems of Schsinadra chinensisas were used as test materials，insecticidal activities and repellent effects of extracts from different parts against Myzus persicae and Plutella xylostella were determined by immersion method.The results showed that all the extracts had insecticidal activities and repellent effects against Myzus persicae at 2 g?L-1，insecticidal activities of oil n-butylalcohol extracts(OB)，fruits n-butyl alcohol extracts(FBU)，fruits water extracts(FW)，stems ethyl acetate extracts(SET)，stems n-butyl alcoholextracts(SBU) were more than 80.0%.Repellent effects of oil n-butylalcohol extracts（OB），fruit extracts(F)，stem petroleum ether extracts(SPE)，stems ethyl acetate extracts(SET)，stems water extracts (SW) were more than 80.0%.Insecticide activities of all the extracts against Plutella xylostella were poor，only SPE reached 60.0%.All the extracts against Plutella xylostella had repellent effect，oil liquid extracts (OL),fruits water extracts（FW），stems n-butyl alcoholextracts（SBU）reached more than 60.0%.Insecticidal effects and repellent effects of the rest of the extracts were poor.
