Abstract: Cotton aphid, Aphis gossypii (Glover) adults were bioassed with Malathion organophosphorrus (OP) insecticide. The roles of carboxyesterases activity in resistance to Ops are discussed along 15 generations. Five substrates (α-naphthyl acetate, Indoxyl acetate, Lurate acetate, Myristate acetate and Acetythiocholine iodide) were screened. The results showed that, esterase activity, measured by using α-naphthyl acetate and Indoxyl acetate can detect the level of OP resistance and used as a marker for OP resistance in field population. Bands No. 1, 3 and 6 were classified as carboxyesterase in resistant strain. The diagnostic resistance-specific esterase bands have been used as a resistance marker to detect the population resistance in field for enhancing the control strategy.
