The life cycle of Metagonimus miyatai Saito, Chai, Kim, Lee and Rim, 1997 (Digenea: Heterophyidae) was studied in the Hiroi River at Kotobuki, Iiyama City, Nagano Prefecture, central Japan. Daughter rediae and cercariae were found in Semisulcospira libertina (Gould) and S. dolorosa (Gould) (Gastropoda: Pleuroceridae). Metacercariae were found encysted in Phoxinus lagowskii steindachneri Sauvage (Osteichthyes: Cyprinidae). Cercariae were experimentally exposed to P. lagowskii steindachneri, and metacercariae were obtained from the fish. Metacercariae of natural and experimental infections were experimentally fed to respective golden hamsters, and gravid adults identifiable as M. miyatai were recovered from the small intestine of the golden hamsters. The daughter redia, cercaria, metacercariae and adults are described. The life cycle of M. miyatai is discussed.
1997年斋藤、柴、金、李和林描述的宫田后殖吸虫（复殖目：异形科）的生活史在日本中部长野县饭山市小牧的广井河中进行了研究。在放逸短沟蜷（古尔德）和痛短沟蜷（古尔德）（腹足纲：肋蜷科）中发现了子雷蚴和尾蚴。在拉氏雅罗鱼斯坦达赫纳亚种（硬骨鱼纲：鲤科）中发现了囊蚴。将尾蚴实验性地暴露于拉氏雅罗鱼斯坦达赫纳亚种，然后从鱼体中获得囊蚴。将自然感染和实验感染的囊蚴分别实验性地投喂给各自的金黄仓鼠，从金黄仓鼠的小肠中回收了可鉴定为宫田后殖吸虫的妊娠成虫。对子雷蚴、尾蚴、囊蚴和成虫进行了描述。并讨论了宫田后殖吸虫的生活史。
