摘要: The broad insecticide chlorantraniliprole causes death by activating the ryanodine receptor, and its effects on detoxification enzymes limit its proper rotation and mixed use with other pesticides. Therefore, we studied the changes in detoxification enzymes activities of Locusta migratoria L. nymphs induced by chlorantraniliprole. When nymphs of locust were treated with chlorantraniliprole only on the first day, the LC50 was 4.8 mu g mL(-1) and the activities of esterases (ESTs) and glutathione S-transferases (GSTs) increased, but the activity of multifunction oxidases (MFOs) increased only at 3 day after treatment, although the activities fluctuated over 7 days after treatment. When the nymphs of locust were treated for 7 days, the LC50 was 2.3-3.1 mu g mL(-1), and similarly the activities of ESTs and GSTs increased while that of MFOs decreased significantly in a concentration dependent manner. Synergism of triphenylphosphate, piperonyl butoxide, and diethyl maleate with chlorantraniliprole toxicity confirmed the correlation between chlorantraniliprole and changes in ESTs, GSTs, and MFOs activities. Herein, we improved the knowledge about the effects of chlorantraniliprole on these detoxification enzymes of L. migratoria. These results clarified the effects of chlorantraniliprole on the activities of ESTs, GSTs, and MFOs in L. migratoria, and will provide insight into its proper rotation and mixed use with other pesticides.
