    Abstract : Residual toxicity of neem [Azadirachta indica] oil alone and in combination with some pesticides was studied against 2 spider mites (Tetranychus hypogaea and T. cinnabarinus) on groundnuts in India. Residual toxicity of synthetic insecticides (phosphamidon and endosulfan) persisted for a few hours and gave 45-50% mortality of T. hypogaea. The crude neem oil at 2% gave the highest LT50 values of 156 h for T. hypogaea and 182.4 h for T. cinnabarinus. Mixture of synthetic insecticides and kelthane with neem oil resulted in higher LT50 than alone.
