The activities of two metabolic enzymes in the imidacloprid resistant (about 7 fold) and susceptible strains of the cotton aphid, Aphis gossypii were compared by biochemical methods. Piperonyl butoxide (Pb) had no synergism to imidacloprid in both of the strains. Activities of carboxylesterases (CarE) and gluathione S transferases (GSTs) in the resistant strain were significantly higher than that in the susceptible one. The K m of CarE in the resistant strain were also significantly higher than… CONTINUE READING
