摘　　要：目的现场评价40%四聚乙醛悬浮剂和某新型50%氯硝柳胺乙醇胺盐可湿性粉剂的杀螺效果。方法选取桐城市范岗镇万元村两干渠有螺环境作为现场进行喷洒试验。四聚乙醛和新型氯硝柳胺均使用有效含量为0.5g/m^2、1.0g/m^2和2.0g/m^2的三种剂最进行试验。同时设立氯硝柳胺对照组和空白对照组。观察各组施药后第1、3、7和15d的钉螺死亡情况。结果四聚乙醛2.0g/m^2组施药后3d钉螺死亡率大于85%,新型氯硝柳胺0.5g/m^2组施药后1d钉螺死亡率大于85%。对各组杀螺效果进行对比,施药后1d,最低有效剂量下,新型氯硝柳胺杀螺效果优于四聚乙醛和氯硝柳胺对照组,施药后3d以后,各组间差异无统计学意义。结论 40%四聚乙醛悬浮剂和新型50%氯硝柳胺乙醇胺盐均为优良的灭螺药,二者各有特点,适用于不同条件下的灭螺工作。Objective To evaluate the molluscicidal effect of 40%Metaeldehyde suspending agent and a new type of wettable powder of 50%Niclosamile ethanolamine salt(WPN) in field.Methods The two molluscicides were divided into 0.5,1.0 and 2.0g/m2 groups,respectively;normal WPN and fresh water were set as control groups.The snail death rates after Spraying mollucicides 1,3,7 and 15 days were investigated.Results When sprayed with active ingredient 2.0g/nr of Metaeldehyde and 0.5g/m2 of the New WPN in the field for 3 days,the snail death rates were above 85%.The snail death rate after 1 day of the New WPN group was higher than Metaeldehyde and normal WPN group in the minimum effective dose,but no statistically significant difference after three days.Conclusion Both 40%Metaeldehyde suspending agent and the New WPN showed high molluscicidal effect on snails.
