| Abstract: | The experiment of toxicity of two pesticides on Bufo gargarizans tadpole was conducted.In acute toxicity test,the LC_(50) of pesticides Ruigao of 24,48 and 72 h to Bufo gargarizans tadpole were 37.279,35.515,35.006 mg/L respectively;and those of pesticides Feiwang to Bufo gargarizans tadpole were 64.423,62.781,62.301 mg/L respectively.In joint toxicity test,the LC_(50) of pesticides Rnigao of 24,48 and 72h to Bufo gargarizans tadpole were 16.205,15.315,13.749 mg/L respectively;and those of pesticides Feiwang to Bufo gargarizans Tadpole were 30.441,28.797,25.898 mg/L respectively.And two pesticides showed an synergistic effect. |
