摘要： 目的 目的 观察5%杀螺胺乙醇胺盐颗粒剂 （NEG） 在云南高原山区的现场杀螺效果。方法 方法 在云南省鹤庆县金墩 乡孝廉行政村北登自然村选取钉螺孳生草地开展现场灭螺试验。试验分7组， 即30、 40 g/m2 和50 g/m2 NEG组， 40 g/m2 NEG + 清障组， 6 g/m2 50%氯硝柳胺乙醇胺盐粉剂 （WPN） 组， 6 g/m2 WPN + 清障组和清水对照组， 灭螺7、 15、 30 d后， 比较 不同组钉螺死亡率和活螺密度变化。结果 结果 施药7、 15、 30 d 后， 30、 40 g/m2 和50 g/m2 NEG组钉螺死亡率为72.75%～ 95.83%， 活螺平均密度下降率为72.26%～95.54%； 随着药物剂量的增加， 钉螺死亡率逐渐上升， 活螺平均密度逐渐下 降。施药7、 15、 30 d后， 40 g/m2 NEG组钉螺死亡率为81.69%～87.19%， 活螺平均密度下降率为81.42%～87.91%； 40 g/m2 NEG + 除障组钉螺死亡率为84.89%～88.24%， 活螺平均密度下降率为85.63%～88.22%； 6 g/m2 WPN组钉螺死亡率为 85.23%～86.17%， 活螺平均密度下降率为85.76%～86.05%； 6 g/m2 WPN + 除障组钉螺死亡率为88.89%～92.10%， 活螺平 均密度下降率为86.71%～92.20%。灭螺前进行割草等环境清障后的灭螺效果相对较好。结论 结论 NEG在云南山区现场 杀螺效果较好， 是一种适合高原山区现场应用的新型杀螺剂。

Abstract: Objective Objective To evaluate the molluscicidal effect of 5% powder of niclosamide ethanolamine salt granules（NEG） in the field of mountainous areas in Yunnan Province. Methods Methods The grasslands with Oncomelania hupensis snail habitats were chosen in Beideng Village，Heqing County，Yunnan Province，and were divided into 7 groups（groups of NEG 30 g/m2 ，NEG 40 g/m2 ，NEG 50 g/m2 ，NEG 40 g/m2 plus obstacle clearing，50% niclosamide ethanolamine salt wettable powder（WPN）6 g/m2 ， WPN 6 g/m2 plus obstacle clearing，and fresh water） . The snail death rates and the densities of living snails were investigated and the results were compared in the different groups 7 d，15 d，and 30 d after the implementation. Resul Result ts s Seven d，15 d， and 30 d after the implementation，the snail death rates of the groups of NEG 30 g/m2 ，40 g/m2 ，and 50 g/m2 were from 72.75％ to 95.83％，and the average descent rates of living snail densities were from 72.26％ to 95.54％. Seven d，15 d，and 30 d after the implementation，in the NEG 40 g/m2 group，the snail death rates were from 81.69% to 87.19%，and the average descent rates of living snail densities were from 81.42% to 87.91%；in the NEG 40 g/m2 plus obstacle clearing group，the snail death rates were from 84.89% to 88.24% and the average descent rates of living snail densities were from 85.63%～88.22%；in the WPN 6 g/m2 group，the snail death rates were from 85.23% to 86.17% and the average descent rates of living snail densities were from 85.76% to 86.05%；in the WPN 6 g/m2 plus obstacle clearing group，the snail death rates were from 88.89% to 92.10% and the average descent rates of living snail densities were from 86.71% to 92.20%. The obstacle clearing improved the molluscicidal effect. Conclusion Conclusion NEG has a good molluscicidal effect in the field of mountainous areas in Yunnan Province.
