Abstract
In the present study crude extracts of C. odorata and L. nepetifolia plants were screened for their ovicidal, antifeedant and larvicidal activity with different concentrations of acetone, methanol and aqueous extracts against the third instar larvae of H. armigera. The highest ovicidal (61.33±0.57% and 63.45±0.77%), antifeedant (62.45±1.26% and 63.17±0.66%) and larvicidal (65.33±3.05% and 68.33±0.57%) activities were recorded in methanol extract (5%) of C. odorata and L. nepetifolia respectively. Further TLC analysis was carried out with four different solvent systems to screen phenolics from methanol extracts. The solvent system benzene: ethyl acetate: formic acid (6:3:1) showed highest 5 spots in both plant extracts compare to other solvent systems.
