摘　　要：2008年8月在血吸虫病重疫区江西省玉山县山丘地区,比较密达利和氯硝柳胺药液喷洒灭螺效果及毒性。分别设密达利田埂组(1g/m2)、密达利田坂组(1g/m2)、氯硝柳胺组(2g/m2)及空白对照组。施药后3d、7d、15d和2个月,各施药组的钉螺校正死亡率均显著高于空白对照组(P值均<0.05),而密达利田坂组则显著低于密达利田埂组和氯硝柳胺组(P值均<0.05)。密达利施药后2个月对非靶生物无明显不良反应,但氯硝柳胺组于施药后1d,鱼、螺和蛙等全部死亡。The molluscicidal effect and toxicity of META-Li were evaluated and compared with niclosamide in Yushan county of Jiangxi Province in August 2008. There are four groups named as META-Li ridge group （1 g/m^2）, META-Li field group（1 g/m^2）, niclosamide group（2g/m^2） and control group. At 3 d, 7 d, 15 d and 2 months after drugs sprayed, the corrected mortalities of snails in the 3 groups were considerably higher than those of control （P〈0.05）. The corrected mortalities in META-Li field group were significantly lower than those of META-Li ridge group and niclosamide group（P〈0.05）. No adverse effect was observed to non-target organisms in META-Li groups, while fishes, snails and frogs all died at the first day after treated with niclosamide.
