摘　　要：目的观察50%氯硝柳胺乙醇胺盐粉剂(WPN)对家蚕的毒性。方法将桑叶在1、2、4、6、8 g/L WPN中浸泡10 s和3 min,然后喂养家蚕,观察家蚕死亡情况。并设清水对照组。结果将桑叶在WPN中浸泡10 s后喂养家蚕21 d,家蚕死亡率为22.5%～85.0%,高于对照组的14.0%;浸泡3 min后喂养家蚕24 d,家蚕死亡率为56.0%～100%,高于对照组的8.5%。结论WPN对家蚕有毒性,须妥善处理灭螺与家蚕养殖的关系。Objective To observe the toxity of niclosamide on the growth of silkworms.Methods Mulberry leaves were soaked in the different concentrations of solution of 50% ethanol salt powder of niclosamide for 10 s or 3 min,and then the leaves were fed to silkworms.The death rates of silkworms and the weight of cocoons were observed.Normal feeding control groups were established.Results The death rates were 22.5%-85.0% and 56.0%-100% in the 10-s-soaked groups and 3-min groups,re spectively,which were significantly higher than those in the control groups.Conclusion The 50% ethanol salt powder of ni closamide has a toxity for silkworm.Therefore,we should properly handle the relationship between the Oncomelania snail control and silkworm breeding.
