Cotton aphid, Ap < /em>his gossyp < /em>ii (Glover) adults were bioassed with Malathion organophosphorus (OP) insecticide. The roles of carboxyesterase activity in resistance to Ops are discussed along 15 generations. Five substrates (a-naphthyl acetate, Indoxyl acetate, Lurate actate, Myristate acetate and Acetylthiocholine iodide) were screened. The results showed that, esterase activity, measured by using a- naphthyl acetate and lndoxyl 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.
