The antifeedant activity of Azadirachta indica (L.) A. Juss (neem) leaf extract, seed kernel extract, and seed oil; Pongamia glabra Vent seed oil; Madhuca latifolia (Roxb.) Macbeth oil and two fungal origin biopesticides, i.e., conidia of Metarhizium anisopliae (Metchnioff) Sorokin and the enzyme preparation of the fungus, Myrothecium verrucaria (Albertini & Schwein) were evaluated against the adult H. vigintioctopunctata under laboratory conditions during 2005-06. Among the botanicals evaluated, P. glabra oil showed the maximum anti-feedant activity. No feeding was observed up to 48 hours after treatment. Mortality was noticed 72 hours after treatment and cent per cent mortality was recorded 7 days after treatment at all the concentrations. Neem oil showed 60 per cent mortality at 5 per cent concentration. The leaf extract and seed kernel extract of A. indica had less anti-feedant activity as compared to the oil formulations of A. indica and M. latifolia (based on the per cent leaf area consumed). A decrease in feeding was evidenced after treatment with M. verrucaria, M. verrucaria and M.anisopliae.
