摘　　要：采用10%氯代水杨胺可湿性粉剂(LDS)人工拌沙撒粉法、26%四聚杀螺胺悬浮剂(MNSC)和50%氯硝柳胺乙醇胺盐可湿性粉剂(WPN)喷洒法在云南山区开展现场杀螺试验,灭螺后7、15、30 d,LDS组钉螺死亡率、活螺密度下降率、活螺框出现率分别为72.69%～87.16%、74.10%～88.84%和20%～30%,MNSC组分别为66.21%～91.06%、69.55%～91.36%和19.44%～27.78%,WPN组分别为78.10%～90.18%、82.44%～91.60%和17.50%～20%。结果显示,LDS、MNSC和WPN灭螺效果基本接近。The molluscicidal effects of 10% salt of quinoid-2＇,5-dichloro-4＇-nitrosalicylanilide（LDS） with dusting method,26% amine molluscicide（MNSC） and 50% niclosamide（WPN） with insufflation method were tested in the fields of mountainous areas of Yunnan Province.After 7,15 and 30 days of the tests,the death rates of snails,decline rates of living snail densities,and occurrence rates of frames with living snails of the 10% LDS group were 72.69%-87.16%,74.10%-88.84%,and 20.00%-30.00%,respectively;those of the 26% MNSC group were 66.21%-91.06%,69.55%-91.36%,and 19.44%-27.78% respectively;those of the 50% WPN group were 78.10%-90.18%,82.44%-91.60%,17.50%-20.00%,respectively.The results showed that the molluscicidal effects of 10% LDS,26% MNSC and 50% WPN were basically equal.
