ABSTRACT: To evaluate the growth and feeding
inhibitory activities leaves extract of Tragia
involucrata tested against third instar larvae of Achaea janata and Pericallia
ricini. Feeding inhibition, larvicidal and growth inhibitory activities
were tested with different solvent extracts of hexane, chloroform and ethyl
acetate. Chloroform extracts showed promising feeding deterrent and larvicidal
activities against A. janata and P. ricini. Percentage of deformed larvae, pupae and adults were
maximum on ethyl acetate extract. Percentage of successful adult emergence was
deteriorated by extract treated larvae. Ethyl acetate extracts of T. involucrata, showed higher percentage of feeding, larvicidal and growth
inhibition activities. Hence, it may suggest it can use for controlling
agricultural insect pests, A. janata and P. ricini.
