Gliricidia sepiumare medicinal plants predominantly present in India. It is also used for its medicinal, insecticidal and insect repellent properties. Larvicidal activity of the petroleum ether, chloroform, ethyl acetate and methanol leaf extracts of G. sepium leaf powder were investigated for their larvicidal property against IV instar larvae of Helicoverpa armigera. The presence of secondary metabolites from all solvent extracts of G.sepiumleaf were analysed. The larval mortality was observed after 24 h of exposure. All extracts showed moderatelarvicidal effects; however, the highest larval mortality was found in methanol extract of G. Sepium against the larvae of H. armigera. Usually larger doses of plant extract inflict mortality either by inhibiting feeding. The study proves an ideal eco-friendly approach for the control of the agricultural pest, H. armigera.
