| Abstract: | Objective]The biological activity of insecticidal components of Seleng Wormwood on cabbage butterfly(Pieris rapae) was studied.Method]With the assisted condition of microwave heating,ethanol,ethyl ether,water and methylbenzene were selected as solvent to extract Seleng Wormwood,the antifeeding,stomach poisoning,contact toxicity and fumigation activities of various solvent extracts against cabbage butterfly were determined.Result]Various solvent extracts all showed certain antifeeding,stomach poisoning,contact and fumigation activities against the larvae of cabbage butterfly,while the biological activity of ethanol extract was the strongest.Conclusion]The results could provide reference for development and utilization of botanical pesticides of Seleng Wormwood. |
