| 摘 要： | Objective] The research aimed to lay a foundation for the screening of cell lines producing secondary metabolites of Brucea javanica(L.)Merr.Method] The insecticidal activities of the extracts from branch and 3 different types of calluses of Brucea javanica(L.)Merr.was detected through methods of leaf disc and potted seedlings against the diamond back moth.Result] Extracts from four kinds of Brucea javanica(L.)Merr.tissues assumed both the activities of antifeedant and oviposition deterrency against the diamond back moth.Antifeedant effect of extracts was in turn the callus C< callus B< callus A< branches.Oviposition deterrency activity of the extracts was in turn the callus A> branch > callus B>callus C.The insecticidal activities of callus A and B were higher than that of the callus C.Conclusion] The results show that insecticidal activity of callus and its growth rate is inversely proportional.
