In order to investigate a possible method of biological control of schistosomiasis, we used the fish Geophagus brasiliensis (Quoy & Gaimard, 1824) which is widely distributed throughout Brazil, to interrupt the life cycle of the snail Biomphalaria tenagophila (Orbigny, 1835), an intermediate host of Schistosoma mansoni. In the laboratory, predation eliminated 97.6% of the smaller snails (3-8 mm shell diameter) and 9.2% of the larger ones (12-14 mm shell diameter). Very promising results were also obtained in a seminatural environment. Studies of this fish in natural snail habitats should be further encouraged.
为了研究一种可能的血吸虫病生物防治方法，我们使用了巴西丽体鱼（Geophagus brasiliensis）（奎伊和盖马尔，1824年），这种鱼在巴西广泛分布，以阻断曼氏血吸虫中间宿主嗜卷钉螺（Biomphalaria tenagophila）（奥比尼，1835年）的生命周期。在实验室中，捕食行为消灭了97.6%的较小蜗牛（壳直径3 - 8毫米）和9.2%的较大蜗牛（壳直径12 - 14毫米）。在半自然环境中也获得了非常有前景的结果。应进一步鼓励在蜗牛自然栖息地对这种鱼进行研究。
