Lymnaea auricularia race rufescens and Lymnaea luteola were shown to transmit F. gigantica in the Koshi hills of Nepal. The ecology of the snails was studied at nine different habitats in Hattikharka panchayat, the highest numbers occurring immediately after the end of the monsoon. Mature F. gigantica infections in the snails were detected from May to August and again in November. The prevalence of the infection in cattle was highest during the summer monsoon and in January and February. A control programme for fascioliasis based on these findings is suggested which requires that cattle be treated in February and possibly again in late August.
在尼泊尔的科希山区，已证实耳萝卜螺指名亚种和黄斑萝卜螺可传播巨片形吸虫。在哈蒂卡卡尔卡村的9个不同栖息地对这些螺的生态进行了研究，发现季风结束后螺的数量立刻达到最多。从5月至8月以及11月再次检测到螺体内有成熟的巨片形吸虫感染。牛感染该病的患病率在夏季季风期间以及1月和2月最高。基于这些研究结果，建议开展一项片形吸虫病防控计划，该计划要求在2月对牛进行治疗，可能在8月底再次治疗。
