The host-specificity of monogeneans in inland waters of China
我国内陆水体单殖吸虫的宿主特异性分析

The host specificity of monogeneans in inland waters of China was studied.The great specificity and the obvious difference of specificity among four major families of monogeneans were observed.According to published records,more than 60% species of monogeneans were found only on 1 host species,and about 75% species on 1 host genus,over 97% species on 1 host family.No monogenean species is able to parasitize on hosts over 3 families,however,the host tree of the monogenean species Dactylogyrus magnihamatus covers 23 genera or 33 species.At the levels of host family or genus,the monogeneans of Ancyrocephalidae and Dactylogyridae have greater host specificity than Gyrodactylidae and Diplozoidae.Deplozoidae has the lowest specificity in the four families.At the level of host species,no significant difference of host specificity was observed among the four families.
