Description Toxicity of different insecticides recommended to control brown plant hopper Nilaparvata lugens (Stal) was evaluated in the laboratory against insect populations collected from Delhi and in its surrounding village Palla. Results showed that endosulfan was most effective with lowest lethal concentrations being 0.0007% against both populations. The values of relative toxicity when calculated in comparison to LC50 value of monocrotophos it was observed that acetamiprid, thiamethoxam, flubendamide, clothinidine and mixture of flubendamide + fipronil were less toxic than monocrotophos, whereas imidacloprid, chlorpyriphos and endosulfan were more toxic to N. lugens. Based on relative toxicity derived on the basis of LC50 and LC97.5 values, endosulfan was highly toxic and most effective insecticides among the insecticides tested.
