Abstract

Hexane, chloroform and ethyl acetate extracts of the leaves of Atalantia monophylla (L.) Correa. were evaluated for their antifeedant and larvicidal activities along with their effect on pupation and adult emergence against bhendi fruit borer, Earias vittella Fab. at 5, 2.5 and 1.25% concentrations. Commercial botanical insecticide, Vijay Neem was used as positive control. Hexane extract at 5% concentration showed significant antifeedant and larvicidal activity of 70.89 and 85.33% respectively. A reduction of 16.66% in adult emergence was recorded in hexane extract followed by 25% reduction in ethyl acetate extract at 5% concentration. The results revealed that hexane extract showed significant antifeedant, and larvicidal activity and good reduction in adult emergence. This extract could be further investigated to isolate the active principles.
