Antifeedant and larvicidal activities of ethyl acetate crude extracts of Jatropha integerrima leaves were tested against fourth instar larvae of Spodoptera litura and Helicoverpa armigera. The maximum antifeedant activity was recorded in ethyl acetate crude extracts of J. integrrima against S. litura (74.33%) and H. armigera (70.11%) at 5% concentration. The maximum larvicidal activity was recorded in ethyl acetate crude extracts of J. integrrima against S. litura (76.84%) and H. armigera (73.12%) at 5% concentration. The antifeedant activity was recorded in chloroform crude extracts of J. integrrima against S. litura (74.33%) and H. armigera (70.11%) at 5% concentration. The larvicidal activity was recorded in chloroform crude extracts of J. integrrima against S. litura (76.84%) and H. armigera (73.12%) at 5% concentration. The antifeedant activity was recorded in hexane crude extracts of J. integrrima against S. litura (74.33%) and H. armigera (70.11%) at 5% concentration. The larvicidal activity was recorded in hexane crude extracts of J. integrrima against S. litura (76.84%) and H. armigera (73.12%) at 5% concentration. These results indicate that J. integrrima has the potential to serve as an alternate botanical pesticide in the management of Spodoptera litura and Helicoverpa armigera.
