Antifeedant and grow th inhibitory activities of hexane, diethyl ether, dicholoromethane and ethyl
acetate crude extracts of Syzygium lineare leaves were tested against fourth instar larvae of Spodoptera litura. All the crude extracts showed antifeedant activity in a dose dependent manner. Significant antifeedant activity
was found only in ethyl acetate extract. Bioctive ethyl acetate extract was subjected to fractionation using silica
gel column chromatography. Seven fractions were obtained. Highest antifeedant activity (91.58%) and larval
deformity were observed in sixth fraction. Third fraction showed high pupal, adult deformities and decreased
adult emergence (30.2%). This plant has the potential to serve as an alternate biopesticide in the management
of Lepidopteron pests.
Key words: Antifeedant, myrtaceae, Spodoptera litura, Syzygium lineare, , ,
