目的：评价荣宝在绵阳市血吸虫病流行区的灭螺效果。方法在绵阳市涪城区杨家镇万和村选择3处螺情相似的有螺环境，分别设为荣宝、氯硝柳胺和清水对照3组，于施药前和施药后7、15、30、60 d开展钉螺调查，比较荣宝和氯硝柳胺的灭螺效果。结果施药7、15、30、60 d后，荣宝组活螺密度下降率分别为94.4%、95.9%、98.2%和98.8%；氯硝柳胺组活螺密度下降率分别为94.0%、94.0%、89.9%和92.2%。施药30 d和60 d后，荣宝组活螺密度下降率高于氯硝柳胺组，差异有统计学意义（χ230 d=8.18，χ260 d=3.97，P均＜0.05）。结论在绵阳市血吸虫病流行区，荣宝近期灭螺效果与氯硝柳胺相当，但远期效果好于氯硝柳胺。

Objective To evaluate the molluscicidal effect of Rongbao in schistosomiasis endemic areas in Mianyang City. Methods Three Oncomelania hupensis snail habitats with the similar snail status were selected and sprayed with Rongbao,ni-closamide,and fresh water,respectively. Then the snail status in the three fields was surveyed before the spraying and 7,15,30 and 60 days after the spraying,and the molluscicidal effects of different molluscicides were compared. Results The reducing rates of densities of living snails in the field sprayed with Rongbao were 94.4%,95.9%,98.2%and 98.8%,7,15,30 and 60 days after the spraying,respectively. The reducing rates of the densities of living snails in the other field sprayed with niclosamide were 94.0%,94.0%,89.9%and 92.2%in above-mentioned days,respectively. In the 30 days and 60 days after the spraying,the reducing rates of densities of living snails in the field sprayed with Rongbao were significantly higher than those sprayed with ni-closamide(χ230 d=8.18,χ260 d=3.97,Both P<0.05). Conclusion The short-term molluscicidal effect of Rongbao is similar to that of niclosamide,but the long-term effect of Rongbao is better than that of niclosamide.
