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
