Abstract The field experiment evaluated efficacy of insecticides against Mylabris phalerata (Pallas) with treatments viz. bifenthrin 62 g a.i./ha, lambda-cyhalothrin (encapsulated with polymers; Matadore) 24 g a.i./ha, chlorpyriphos 310 g a.i./ha+ cypermethrin 31 g a.i./ha, cypermethrin 62 g a.i./ha, neem oil 1500 ppm, permethrin 154 g a.i./ha, chlorpyriphos 173 g a.i./ha. After five days of spray, maximum efficacy was obtained from bifenthrin which was at par with lambda-cyhalothrin, permethrin, cypermethrin, chlorpyriphos+ cypermethrin and all these were significantly superior over chlorpyriphos and neem oil. After ten days of spray, maximum efficacy was again with bifenthrin which was at par with lambda-cyhalothrin, and these were significantly superior over rest of the treatments. Lambda-cyhalothrin was the effective and most lucrative. Top Keywords Insecticides, Mylabris phalerata, soybean, bifenthrin, lambda cyhalothrin, permethrin, cypermethrin, chlorpyriphos, neem oil.
