Abstract:
Objective To evaluate the effect of the water conservancy schistosomiasis control projects combined with mollus-cicide to control Oncomelania hupensis snails in the rivers connecting with the Yangtze River. Methods The water conservancy schistosomiasis control projects of Zhujiashan River,Qili River and Gaowang River were chosen as the study objects in Pukou District,Nanjing City. The data review method and field investigation were used to evaluate the effect of the water conservancy schistosomiasis control projects combined with molluscicide to control O. hupensis snails. Results After the projects of the wa-ter level control and concrete slope protection and mollusciciding were implemented,the snails in the project river sections were completely eliminated. The snail diffusion did not happen in the inland irrigation area too. In the outside of the river beach , though the snails still existed,the snail densities plunged below 1.0 snail per 1.0 m2. Conclusion The comprehensive mea-sures of the combination of water level control,concrete slope protection and mollusciciding can effectively control and eliminate the snails,and prevent the snails from spreading.
