The natural infecton rate and seasonal variation of Echinochasmus liliputanus in intermediate hosts were observed during 1991-1993 in Chenqiaozhou village ,Hexian county,An-hui Province. Bellamya aeruginosa was found as first intermediate host of the parasite for thefirst time and its natural infection rate varied with seasons. The cercariae in the snails began toappear in later July, peaked during September to November , and disappeared in early December.Itwas wlAely adapted to varieties of second intermediate hosts ,being present in almost all fishessurveyed.
