Non-target adults of Cydia pomonella are exposed to insecticide concentrations that maynot result in mortality. The present study evaluates the response of biotransformation andantioxidant parameters to acetamiprid-sublethal exposure of surviving adults from both alaboratory-susceptible strain (LSS) and a field population (FP). Activities of 7-ethoxycoumarineO-deethylase (ECOD), glutathione S-transferases (GST) and catalase (CAT), as well asglutathione (GSH) content were examined. The FP displayed a significantly higher ECODbasal activity than the one from LSS. Acetamiprid exposure in FP elicited a significantincrease in ECOD activities. GSH content was significantly affected in LSS and FP adultstreated with 100mg/L of acetamiprid. The FP responded to acetamiprid with both anincrease of ECOD activity and GSH content in a concentration-dependent manner. CAT andGST activities from both LSS and FP were mostly unaffected by the concentrations of acetamipridevaluated. Obtained results are helpful in anticipating the development of resistantpest populations to insecticides.
