Abstract :

In the present study, the antifeedant, larvicidal activities of synthesized silver nanoparticles (Ag NPs) using aqueous leaf extract of Aristolochia indica against third instar larvae of Helicoverpa armigera and were evaluated. Antifeedant, larvicidal activities of aqueous crude extracts and synthesized Ag NPs were studied using leaf disc no choice, leaf dipping methods respectively. The maximum antifeedant and larvicidal efficacy was observed in crude aqueous and synthesized Ag NPs against H. armigera larvae (LC50 = 127.49, 84.56 mg/L; 766.54, and 309.98 mg/mL), respectively. It is a novel, eco-friendly, simple, and cost-effective approach to synthesis of Ag NPs using A. indica to control the pest.
