摘要：Chemical and synthetic pesticides used for controlling various plant pest have resulted in thedevelopment of resistance to several classes of pesticides. In the present study, five medicinal plants were screened fortheir ovicidal activity againstHelicoverpaamigera ,Spodopteralitura ,Plutellaxylostella,Corcyracephalonica. Hexane,Diethyl ether extract of plants was studied at 1% concentration. Effective plant extracts identified based on totalantioxidant, flavonoid and phenolic contents and Maximum ovicidal activity was recorded in hexane extract ofVitexagnuscastus (96%) for Spodoptera,(93.5%) for Plutella and (90.5%) for Corcyra followed by hexane extract ofRicinuscommunis (92%) for Corcyra and Pongamiapinnata(84.5%) for Corcyra. Diethyl ether extract showed loweractivity when compared to hexane extract. Further isolation and identification of bioactive principles responsible for theovicidal activity is needed.
