摘要：

目的目的评价植物杀螺剂4%螺威（TDS）在湖沼地区现场灭螺效果，为大规模现场应用提供科学依据。方法方法在江西省星子县和湖南省华容县各选择1个环境采用5 g/m2 TDS进行喷洒灭螺试验，并与2 g/m2 50%氯硝柳胺乙醇胺盐（WPN）进行对比观察，统计分析不同地区、不同药物、不同时间现场杀螺效果。结果结果星子和华容2个现场灭螺后 1、 3、 7、 15 d， TDS组与WPN组钉螺死亡率总体均呈逐渐升高趋势。灭螺后15 d，星子现场TDS组与WPN组钉螺死亡率分别为86.53% 和83.04%，华容现场TDS组与WPN组钉螺死亡率分别为88.28%和93.69%；星子和华容现场TDS组活螺密度下降率分别为 88.86%和87.99%， WPN组活螺密度下降率分别为85.29%和93.53%。结论结论 TDS在湖沼型血吸虫病流行区现场杀螺效果较好，具备了开展现场推广应用的条件。

Abstract:

Objective To evaluate the field effect of a novel plant molluscicide“Luo ?wei” （Tea ? seed distilled saponins， TDS）against Oncomelania hupensis in the lake and marshland regions. Methods A spraying experiment was carried out in the grassland of two schistosomiasis endemic counties，including Xingzi in Jiangxi Province and the Huarong in Hunan Province，to assess the molluscicidal effect of 4% TDS comparing with 50% wettable powder of niclosamide ethanolamine salt（WPN） . The χ2 test was used to examine the differences between regions，molluscicides，or days after spraying. Results Following 1，3，7，and 15 days of test，the snail mortality showed a simultaneous increase both in TDS group（70.43%-86.88%）and WPN group （70.21%-85.35%） . There is no significant difference between TDS and WPN of day 1，7 and 15（all P values > 0.05），but except for day 3（χ2 =3.910，P = 0.048） . By the end of day 15，the snail mortality for TDS was 86.53% in Xingzi and 88.28% in Hua? rong，while for WPN was 83.04% in Xingzi and 93.69% in Huarong respectively；the decline rate of snail density for TDS was 85.29% in Xingzi and 93.53% in Huarong，while for WPN was 85.29% in Xingzi and 93.53% in Huarong respectively. The adjust? ed mortality of different days ranged from 69.63% to 86.54% in the the TDS group，and 69.41% to 86.54% in the WPN group. Conclusion The molluscicidal effect of TDS by spraying is similar to that of WPN. It is time to popularize this new plant mollusci? cide（TDS）in a wider field.
