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.

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。
