本文报道了在室内两种水状态下尾蚴期望寿命的实验观察。结果在25℃恒温条件下，日本血吸虫尾蚴在静水中的平均期望寿命为27．52h，最长存活时间为46h；在动水中的平均期望寿命为25．04h，最长可存活50h。
This article reports the experimental observation of the expected life span of cercariae in two indoor water states. Results The average life expectancy of Schistosoma japonicum cercariae in still water at 25 ℃ was 27.52h and the longest survival time was 46h. The average life expectancy in moving water was 25.04h and the longest survival time was 50h.
