1·No Oncomelania snail was found in 4 spots of Tanghe County and Xinye County.
在唐河县、新野县4个调查区未查到钉螺。
2·CONCLUSION The pumping water from middle of water body is very effective for prevention of oncomelania snail spread.
目的评估电灌站中层抽水阻止钉螺扩散的效果。
3·Objectives to understand the fluctuation and distribution pattern of Oncomelania snails after migrated into marshland where no snail infested.
目的阐明长江下游地区钉螺再次迁入无螺江滩后的钉螺消长和分布变迁规律。
4·Objective to explore the model of Oncomelania snail survey in inland areas, so as to reduce the burden of farmers as well as to improve the quality of snail survey.
目的对内陆地区查螺模式进行探索，以减轻农民负担，提高查螺效率与质量。
5·The researchers found that an increase in the length of time environmental conditions were ideal for the growth of both the Oncomelania snail and the Schistosome worm.
研究人员发现适宜于钉螺和血吸虫生长的时期在过去几十年中有不同程度的延长。
6·So, it was necessary to strengthen surveillance of the potential Oncomelania snail habitats in Three Gorges reservoir region to prevent the snail spreading from Hubei and Sichuan areas.
可见，该区域的气候生态环境能够满足钉螺生长发育繁殖的需求，必须加强对巫山大昌钉螺可能孳生区域的重点监测，以防止湖北、四川血吸虫病疫区钉螺输入。
7·Objective To identify Oncomelania hupensis snail habitats and areas with high transmission potential by GIS/RS.
目的应用地理信息系统和遥感技术（GIS ，RS）快速确定鄱阳湖区钉螺孳生地带及血吸虫病高危区域。
8·Niclosamide was the only WHO recommended molluscacide, and was widely used to kill oncomelania to prevent and cure of snail fever.
氯硝柳胺是WHO唯一保留推荐使用的灭螺药，广泛用于杀灭钉螺预防血吸虫病，同时氯硝柳胺还是一种良好的驱除绦虫的药物。
