Study on Protective Effect of Different Solvent Extracts from Walnut Green Husk on Tobacco Budworm
Using water,ethanol,chloroform,ethyl acetate and ethyl ether five different polar solvents,effective components from walnut peel were extracted by ultrasonic extraction,and then the tobacco budworm poison and antifeedant activity were studied.The results showed that five kinds of extracts had toxic effect on tobacco budworm,and showed a good dose-response relationship,different extracts of different concentrations would affect the tobacco budworm toxicity and antifeedant activity.The order of insecticidal activity of five kinds of extracts to the tobacco budworm was ethyl acetate extract>chloroform extract> ethyl ether extract> ethanol extract.Thus,different solvent extracts from walnut green husk has certain toxic effect on tobacco budworm,has potentiality in biological pesticide development.
