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(1 g/m2)、密达利田坂组(1 g/m2)、氯硝柳胺组(2 g/m2)及空白对照组。施药后3 d、7 d、15 d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1 d, 鱼、螺和蛙等全部死亡。

Abstract:

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/m2), META-Li field group(1 g/m2), niclosamide group(2 g/m2) 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.

Key words: META-Li, Oncomelania hupensis, Niclosamide, Molluscicidal effect
