摘　　要：为研究农药对低等水生动物的影响,研究了草甘膦、乙草胺、敌百虫、敌杀死4种农药对涡虫的急性毒性。结果显示草甘膦、乙草胺、敌百虫、敌杀死对涡虫的24 h LC50分别是:41.78、12.22、1.45、1.42 mg/L;48 h的LC50分别是35.42、8.41、1.34、1.37 mg/L;72 h的LC50分别是29.83、7.46、1.29、1.32 mg/L;96h的LC50分别是27.97、6.98、1.231、.27 mg/L。4种农药对涡虫的安全浓度分别是草甘膦(7.64 mg/L)、乙草胺(1.19 mg/L)、敌百虫(0.34 mg/L)、敌杀死(0.38 mg/L),对涡虫的急性毒性是敌百虫>敌杀死>乙草胺>草甘膦。实验结果表明涡虫用于监测草甘膦、乙草胺、敌百虫、敌杀死对低等水生动物的影响具一定可行性。To research effects of pesticide on the growth of animals living in water, we have studied the acute toxicity of glyphosate ,acetochlor, trichlorphon and decis to Dugesia japonica . Found finally, the LC50 of glyphosate , acetochlor, trichlorphon and decis were 41.78,12.22,1.45,1.42 mg/L after 24h, 35.42,8.41,1.34,1.37V after 48h, 29.83,7.46,1.29,1.32 mg/L after 72h, and 27.97,6.98,1.23, 1.27 mg/L after 96h. The safe concentrations（mg/L） of these pesticide were glyphosate（7.64 mg/L）, acetochlor（1.19 mg/L）,trichlorphon（0.34 rag/L）, decis（0.38 mg/L）. The results showed these acute toxicity were trichlorphon〉 decis 〉 acetochlor 〉 glyphosate. It is feasibility that the planaria D. japonica could be used in monitoring the effects of glyphosate, acetochlor, trichlorphon and decis on the low aquatic animals in a way.
