Chemical and synthetic insecticides used for controlling Spodoptera litura resulted in the development of resistance to
several classes of insecticides. In the present study, a total of twenty five plants were screened for their ovicidal activity
against Spodoptera litura. Hexane, diethyl ether, dichloromethane and ethyl acetate extract of twenty five plants were
studied at 0.1% concentration. Effective plant extracts identified from the preliminary study (0.1%) were further studied
at 0.05% concentration. Maximum ovicidal activity was recorded in hexane extract of Cleistanthus collinus (85.16%)
followed by Murraya koeingii diethyl ether (83.60%) and Aegle marmelos ethyl acetate (76.14%) extract at 0.05%.
Further isolation and identification of bioactive principles responsible for the ovicidal activity is needed.
