Abstract: Oncomelania hupensis is the only intermediate host of Schistosoma japonicum, and control of Oncomelania snails is an important measure to control and interrupt the transmission of schistosomiasis. Therefore, snail control plays a very critical role in the national schistosomiasis control programmes of China. Pyriclobenzuron, which was recently developed by National Institute of Parasitic Diseases, Chinese Center for Disease Control and Prevention, is the latest great advance in the research on molluscicides and is expected to solve the problem of toxicity to fish, which is worthy of expanding experiments.

Key words: Oncomelania hupensis, Schistosomiasis, Molluscicide, Pyriclobenzuron

摘要： 钉螺是日本血吸虫的唯一中间宿主，消灭钉螺是控制和阻断血吸虫病传播的重要措施之一。因此，灭螺在我国血吸虫病防治工作中占有非常重要的地位。中国疾病预防控制中心寄生虫病预防控制所研发的吡螺脲是灭螺药研究的最新重大进展，有望解决灭螺药对鱼类毒性大的问题，值得进一步扩大试验。
