Abstract Spodoptera litura (F.) reared on three host plants viz., castor, cotton and soybean showed variation in susceptibility to indoxacarb15.8EC and chlorantraniliprole 18.5SC. Against F3 generation these two insecticides were more toxic when reared on castor (0.036 ppm LC50-indoxacarb and 0.035 ppmchlorantraniliprole) followed by soybean. Higher LC50 of indoxacarb and chlorantraniliprole (0.172, 0.184 ppm, respectively) was observed when reared on cotton indicating that feeding on cotton induced tolerance. Top Keywords Spodoptera litura, reared on castor, cotton, soybean, indoxacarb, chlorantraniliprole, LC50, tolerance induced by cotton. Top |
