Fifteen colonies of Oncomelania hupensis were found near trails transecting the North Lore District, Napu Valley, Central Sulawesi. Habitats were in abandoned rice fields, uncultivated grazing areas for livestock, roadside ditches and, in one case, an actively worked rice field. Marsh grasses, Ischaemum barbatum and Laersia hexandra, were the most common plants in oncomelanid habitats. Other mollusks found in association with O. hupensis were Radix sp., Melanoides sp., Gyraulus sp., Idiopoma sp., Thiara sp., Opeas sp. and Indopyrgus sp. in that order of frequency. Schistosoma japonicum cercariae, as determined by mouse exposures, were shed from snails collected at four foci. In Sulawesi, O. hupensis and S. japonicum were found in high mountain valleys near, or above, 1,000 meters in elevation. Oncomelania hupensis, however, were not found in what appeared to be suitable habitats at lower elevations in the same drainage systems.
在中苏拉威西省纳普谷北洛雷区的小径附近发现了15个湖北钉螺群落。其栖息地包括废弃稻田、未开垦的牲畜放牧区、路边沟渠，还有一处是正在耕种的稻田。在湖北钉螺的栖息地中，最常见的植物是沼泽草、毛叶鼠尾粟和六蕊短颖草。与湖北钉螺共生的其他软体动物依次为萝卜螺属、拟黑螺属、椎实螺属、粒帽螺属、瓶螺属、烟管螺属和印尼矮蜷属，出现频率按上述顺序排列。通过小鼠感染实验确定，在四个疫点采集的钉螺体内发现有日本血吸虫尾蚴。在苏拉威西岛，湖北钉螺和日本血吸虫出现在海拔1000米及以上的高山山谷中。然而，在同一排水系统较低海拔处看似适宜的栖息地中却未发现湖北钉螺。
