It was observed that the Tarebia granifera plays a significant role in the control of a Biomphalaria peregrina population introduced in a permanent water body. The densities of this planorbid, which had reached high levels, were notably reduced by two important events: an increase of the water level due to heavy rains, and the introduction of the competitor, whose effectiveness had been tested in a different habitat. Knowledge on the ecology and biology of the competitor and the host in permanent water bodies helped to elaborate the measures of control which led to the reduction of the host densities while those of the competitor increased.
据观察，福寿螺在控制引入永久性水体中的南美膀胱螺种群方面发挥着重要作用。这种扁卷螺的密度曾达到很高水平，但由于两个重要事件而显著降低：暴雨导致水位上升，以及引入了竞争者，其有效性已在不同栖息地得到测试。关于永久性水体中竞争者和宿主的生态学和生物学知识有助于制定控制措施，这些措施导致宿主密度降低，而竞争者的密度增加。
