摘　　要：目的观察4%强螺杀粉剂在现场大面积江滩地区的杀螺效果。方法在扬州市邗江区沿江有螺滩地用50g/m24%强螺杀粉剂和2g/m250%氯硝柳胺乙醇胺盐可湿性粉剂,分别在清障与不清障环境下进行喷粉和喷洒法灭螺,并于施药后3、7、15d和12个月,分别观察滩地钉螺死亡情况和活螺密度。结果在清障环境下,灭螺后3、7d和15d的近期杀螺效果,除3d喷洒法杀螺率高于喷粉法外(χ23d=4.6822,P<0.05),7d和15d杀螺率差异均无统计学意义(χ72d=0.0426,χ125d=0.6247,P均>0.05);在未清障环境下,3、7d和15d喷粉法杀螺率显著高于喷洒法(χ32d=4.8456,χ72d=3.8786,χ125d=4.6010,P均<0.05)。但两药12个月后无论清障或未清障,滩地除活螺密度降低外,其杀螺率与近期效果相比均呈现下降趋势。结论4%强螺杀粉剂的近远期杀螺效果好于50%氯硝柳胺乙醇胺盐可湿性粉剂,适宜远离水源江滩和大面积滩地灭螺。To explore the molluscicidal effect of 4% qiangluosha powder （50 g/m^2） and 50% wettable powder of niclosamide ethanolamine salt （2 g/m^2）under the condition of clear or natural environment. The results showed the molluscicidal rate of the salt was higher than that of the powder for 3 days （χ23 d = 4.682 2,P〈 0.05）,but the differences were not significant for 7 days and 15 days （χ^27 d = 0.042 56,χ^215 d = 0.624 73,P〉 0.05） under clear environment. However,under natural environment,the molluscicidal rate of the powder was much higher than that of the salt by using spraying method（χ23 d = 4.845 6,χ^27 d = 3.878 6,χ^215 d = 4.601 0,all P values〈 0.05）. It is indicated that the long-term molluscicidal effect of qiangluosha powder was better than that of wettable powder of niclosamide ethanolamine salt,and the powder was very suitable to be used at large marshland which was far away from water source.
