| 摘 要： | 目的]通过测试印楝素、除虫菊素、鱼藤酮3种植物源农药对鹌鹑和斑马鱼的急性毒性,评价其对环境的安全性。方法]采用一次性＂经口染毒法＂和＂半静态法＂,确定3种农药对鹌鹑和斑马鱼的毒性大小与分级。结果]印楝素、除虫菊素、鱼藤酮对鹌鹑急性毒性的LD50（168h）分别为13.09、97.04和111.75mg/kg.bw;对斑马鱼急性毒性的LC50（96h）分别为0.05、0.15和0.03mg/L。印楝素对鹌鹑的急性经口毒性等级为高毒,除虫菊素和鱼藤酮为中毒;印楝素和鱼藤酮对鱼的急性毒性等级为剧毒,除虫菊素为高毒。结论]3种药剂对鹌鹑和斑马鱼都不安全,实际应用中必须减少其对生态环境的危害。

| Abstract: | 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. |
