Abstract: The toxicity of four insecticides to Aphanostigma jakusuiensis was tested with the dip method. The results showed that when the temperature was 20℃, the LC50 value of imidacloprid was 6.4121 mg/L, the contact toxicity was obviously higher than any of acetaniprid, thiamethoxam and F4 EC, when the temperature was 25℃ and 30℃, the LC50 of acetaniprid were 2.8281 mg/L and 1.5495 mg/L respectively, the contact toxicity was the highest of the four insecticides. The experiment of four insecticides at the same temperature showed that when the temperature was 30℃, the contact toxicity of all the four insecticides was the highest, the LC50 were 10.0369, 2.3686, 1.5495 and 9.2555 mg/L respetively, the temperature influenced their toxicity to Aphanostigma jakusuiensis.
