摘　　要：[目的]寻找克螨特用于水生动物斑马鱼病虫害防控的安全浓度.[方法]通过室内急性毒性测定试验,设置7个克螨特浓度梯度来检测其对斑马鱼的致死情况,从而计算其半致死浓度（LC50）与安全浓度（SC）.[结果]克螨特对斑马鱼在用药96h后的LC50为0.909 mg/L,置信区间分别为0.876-0.943 mg/L.克螨特对斑马鱼的SC为0.091 mg/L.[结论]该研究为克螨特杀灭斑马鱼寄生虫的用药量提供了重要的数据支持.[ Objective ] The research aimed to obtain propargite safe concentrations for pest prevention in zebrafish. [ Method ] In term of the interior of the experimental determination of the acute toxicity test, the research set up 7 concentration gradient of propargite to detect the death quantity of zebrafish, then work out LC50 and SC. [ Result] The results showed that zebrafish median lethal concentration （LC50） was 0.909 mg/L after explosion for 96 h to propargite, confidence interval was 0. 876 - 0. 943 mg/L. Meanwhile, propargite safe drug concentration to zebrafish was 0. 091 mg/L. [ Conclusion] This study provides an important data to support for amount of medication propargite kill zebrafish dactylogyrus.
