Abstract: Oncomelania hupensis，which plays an important role in the transmission of schistosomiasis japonica，is the only intermediate host of Schistosoma japonicum，and carrying out studies on its subspecies differentiation and genetic variation will have an important significance for schistosomiasis control. In this paper，the research progress of taxonomy and discrimination techniques of O. hupensis is reviewed at four levels，namely the morphological level，the cellular level，the protein level，and the DNA molecule level，and DNA sequencing technology is considered as the ideal taxonomy and discrimination technique of O. hupensis and the future research emphasis.

Key words: Oncomelania hupensis； Subspecies differentiation； Discrimination techniques

摘要： 湖北钉螺是日本血吸虫的惟一中间宿主， 在日本血吸虫病传播过程中起着重要作用， 研究其种下分化及遗传变 异对于防治血吸虫病具有重要意义。本文从形态学水平、 细胞水平、 蛋白质水平和DNA分子水平等方面对湖北钉螺的 分类鉴定技术研究进展进行了综述， 并认为DNA序列测定技术是目前湖北钉螺分类鉴定的理想技术和今后的研究重 点。
