abstract
The crude methanolic extracts of Jatropha curcas (L.) were screened (leaf, bark, seed, seed coat and root) for insecticidal activity against third instar larvae of Spodoptera litura using leaf dip bioassay method. Among the tissues screened (leaf, bark, seed, seed coat and root), the leaf extract was most effective and showed highest mortality (60%) at 5% concentration as compared to other extracts followed by seed (20%), seed coat (20%) and root (20%).
