CHEN Ang et al(Longping Branch,Graduate College,Central South University,Changsha,Hunan 410125)  
[Objective]Acute toxicity were tested of three botanical pesticides including Azadirachtin,Pyrethrins and Rotenone on Coturnix coturnix japonica and Brachydonio rerio,respectively,in the laboratory,to estimate the environmental securities of the three pesticides.[Method]The oral exposure and semi-static methods were used to determine the toxicity degree and rank of three pesticides on Coturnix coturnix japonica and Brachydonio rerio.[Result] LD50(168 h)of the acute toxicity of Azadirachtin,Pyrethrins and Rotenone on Coturnix coturnix japonicas were:13.09,97.04,111.75 mg/kg·bw and LC50(96 h)on fishes were 0.05,0.15,0.03 mg/L resp.The acute oral toxicity degree of Azadirachtin on Coturnix coturnix japonica was highly toxic,Pyrethrins and Rotenone were medium.Azadirachtin,and Rotenone on fish were hypertoxic,Pyrethrins was highly toxic.[Conclusion]Three pesticides are all unsafety to Coturnix coturnix japonica and Brachydonio rerio,and it must reduce the harmfulness to ecotope in practical applications.
