A study was carried out on Tarebia granifera in Camagüey which allowed to gather ecological evidence in order to know this freshwater mollusk species likely to act as a biological control agent of intermediate hosts for tropical diseases. Highest density was observed in November, coinciding with the highest temperatures of a running water habitat. Also, there was an influence of density variations according to variations of ions NH4+, NO2- and NO3- concentrations in the medium. These data are useful to know the right time for extracting Tarebia granifera from the habitat and using it as competitor without considerable alterations in the population stability.
在卡马圭对大瓶螺进行了一项研究，该研究收集了生态证据，以便了解这种淡水软体动物物种作为热带疾病中间宿主的生物控制剂的可能性。11月观察到最高密度，这与流水栖息地的最高温度相吻合。此外，根据介质中离子NH4+、NO2-和NO3-浓度的变化，密度也会受到影响。这些数据有助于确定从栖息地提取大瓶螺并将其用作竞争者的合适时间，同时不会对种群稳定性造成显著改变。
