ABSTRACT

Laboratory study was carried out to evaluate the antifedent activity of Adhatoda vasica L. extracts on Spodoptera litura (Fab.) larvae. Various concentrations (25, 50, 75 and 100%) of A. vasica extracts were used against last instar of S. litura. Adhatoda vasica used as biopesticide because it showed a high degree of antifedent activity against this pest. Helianthus annus L. and Hibiscus esculentus are common oil producing vegetable crops respectively; they are very often infected by various pests. Among them S. litura is the major pest. When A. vasica plant extract of different concentrations were sprayed on the above two plants and observed, as the concentration of the plant extract increase the food consumption was decreased. The same trends were also noticed in the percent feeding and percent protection.
