Screening of Plant Extracts for Oviposition Activity against Spodoptera Litura (Fab). (Lepidoptera: Noctiduae

Abstract

Crude extracts of twenty five plants were screened for their oviposition activity against the third instar larvae of Spodoptera litura. Among the twenty five plants tested, oviposition deterrent activity (above fifty per cent) was recorded in only three plants viz., Aegle marmelos ethyl acetate, Cinnamomum zeylanicum hexane and Ocimum americanum ethyl acetate extracts against Spdoptera litura while rest of the plants exhibited varying degree of lesser or moderate effects.
