Abstract

Effects of the ultrasonic treatment on plant represents antifeeding activity and chitin synthesis inhibition activity against diamondback moth (Plutella xylostella L.) by a leaf-dipping method at a concentration of 5,000ppm. Methanol extracts of leaves of the ultrasonic treatment on plant was sequentially partitioned with n-hexane, chloroform, ethlyacetate, butanol and water fractions, and bioassayed. Antifeeding activities were observed in n-hexane, chloroform and ethlyacetate fractions. N-hexane fraction has 94.6% of strongest antifeeding activity against P. xylostella. From the n-hexane sequentially partitioned showed H6 and H8 fractions of antifeeding activities against P. xylostella. And chitin synthesis inhibition activity against P. xylostella was obtained the methaol, n-hexane and water fractions.
