Effect of crude extract of Atalantia monophylla L. on ovicidal activity against Helicoverpa armigera Hubner (Lepidoptera: Noctuidae) and preliminary phytochemical study

Abstract

Methanol, acetone and water crude extracts of Atalantia monophylla leaf were studied for ovicidal activity against Helicoverpa armigera. The sample concentration at 0.1, 0.2, 0.6, 0.8 and 1.0% were used in present experiment. Among the three solvents tested at all concentrations for ovicidal activity, acetone extract 5% was found to be statistically significant( 49%) followed by methanol and aqueous leaf extract. Aqueous leaf extract even at 5.0% was noticed least value. The leaf extract tested was exhibited the presence of phytochemicals such as alkaloids, terpenoids, flavonoid, saponins, phenols and anthraquinone in different solvent extracts.
