Abstract
Rice moth Corcyra cephalonica is a major pest of stored cereals and other commodities in India as well as in other tropical and subtropical regions of the world. Different concentrations of Tylophora indica leaves extracts were mixed flour and C. cephalonica larva were reared on the mixed flour and the mortality was recorded. LD50 values recorded for the fifth instar C. cephalonica exposed to T. indica for 36 hours was 3.502 mg/25 g and the corresponding values recorded for 96 hours was 2.164 mg/ 25 g. Phytochemical analysis of T. indica leaves extracts revealed the presence of cynogenic glycosides, flavanoides, tannins and phenols. The GC-MS result clearly indicated the presence of certain bioactive compounds like Squalene, 1, 2 Benzenedicarboxlicacid disooctyl ester. Since the plant had insecticidal properties they are potentially suitable for integrated pest management.
