title: [Susceptibility and related physiological and biochemical mechanisms of Carposina niponensis Walsingham larvae on six insecticides before and after overwintering].
abstract: The study with impregnating method showed that after overwintering, the susceptibility of Carposina niponensis larvae on triazophos, phoxim, chlorpyrifos, malathion, lambda-cyhalothrin and abamectin was 34.50, 16.71, 3.89, 3.28, 5.90 and 2.73 times as much as that before overwintering, the total protein, glycogen and fat contents and carboxylesterase, acid phosphatase, alkaline phosphatase, glutathione-S-transferase, superoxide dismutase, catalase and peroxidase activities in C. niponensis larvae were decreased by 17.10%, 41.76% and 30.08%, 62.36%, 53.47%, 76.19%, 80.60%, 18.77%, 14.16% and 64.02%, respectively, and the activity of acetylcholinesterase, the target enzyme of many insecticides, was 1.41 times as much as that before overwintering. It was suggested that the difference of the susceptibility was resulted from the changes in the contents of biochemical substances and the activities of metabolic enzymes, protective enzymes and target enzyme.
