is an annelid symbiotically associated with lymnaeid snails as . This association is considered a preventive mechanism against trematode miracidia infection, including . The objective of this study was to determine the effectiveness of as a natural controller of in laboratory conditions.
miracidia were inoculated in parallel into snails carrying and snails without the annelid. The degree of infection was measured after 40 days of exposure. Furthermore, the number of annelids per snail was quantified, as well as the ability of to devour miracidia at different times of exposure.
An effective 70% natural control of in was observed. The carrying capacity of the snail was established to be of 10.6 ± 1 annelids. is a predator of devouring an average of 3.79 ± 0.21 miracidia. The results of these experiments have a potential value as a control measure against fascioliasis in the environment.
是一种与椎实螺共生的环节动物。这种关联被认为是一种针对吸虫毛蚴感染的预防机制，包括。本研究的目的是确定在实验室条件下作为的天然控制剂的有效性。
将毛蚴平行接种到携带的蜗牛和没有该环节动物的蜗牛中。暴露40天后测量感染程度。此外，对每只蜗牛体内环节动物的数量进行了量化，以及在不同暴露时间吞噬毛蚴的能力。
观察到对的有效自然控制率为70%。蜗牛的承载能力确定为10.6±1只环节动物。是毛蚴的捕食者，平均吞噬3.79±0.21个毛蚴。这些实验结果作为环境中对片形吸虫病的控制措施具有潜在价值。
