西昌市养殖灭螺防治日本血吸虫病试点示范技术研究

Research on Demonstrating Experimental Technology of Raising Killing Snail to Prevent Japanese Snail Fever in Xichang

为探索养殖鱼、鸭生物灭螺防治日本血吸虫病技术,在全市选点示范扩建鱼塘和沟渠稻田放养鱼,鸭采食钉螺进行生物灭螺防治血吸虫病,通过五年的示范研究和推广,使疫情得到显著控制,钉螺感染率和感染钉螺密度分别下降71.84%,80.00%,耕牛和人群血吸虫病感染率分别下降73.36%,48.05%,社会经济和生态效益明显。

In order to explore the technology of raising killing snail to prevent japanese snail fever,some experimental fish pools,creeks and paddy fields were picked out for raising fish and ducks feeding on killing snails to prevent japanese snail fever. After five years' demonstrative research and poputarization,the epidemic is drastically under control,and snail infection rate and density havedrpped by 71.84% and 80.00% respectively. Infection rates of ploughing oxen and human beings have dropped by 73.36%and 48.05% respectively,with apparent social economic and ecological benefits.
