Title: The sensitivity of Aenasius bambawalei to chlorpyrifos and imidacloprid and its detoxification enzyme activities
Abstract: In this paper,LC50 of chlorpyrifos and imidacloprid to Aenasius bambawalei were estimated by spray and leaf-dipping methods,the individual development together with parasitization efficiency and some relative detoxification enzymes of the parasitoids were determined by spray method. The results showed that 1) by spray,LC50 to chlorpyrifos was 2. 595 μg·L- 1,and imidacloprid was 0. 115 mg·L- 1; 2) by leaf dipping method,chlorpyrifos was 0. 112μg·L- 1,and imidacloprid was 0. 234 mg·L- 1; and 3) the lethality of chlorpyrifos was higher than imidacloprid.These two pesticides had significant effects on the parasitization efficiency of the parasitoid,but no effect on the hind tibia length of the adults. Activity of Ach E after chlorpyrifos treatment was inhibited by 76. 4%,while activities of Car E and MFO in the imidacloprid treatments were inhibited by 85. 3% and 32. 2%.
