In the laboratory, Peromyscus bearing a single Cuterebra larva are no more vulnerable to weasel predation than are uninfected control mice, and may be taken less often under certain conditions. Mice bearing two or more larvae appear to be more vulnerable than either controls or singly infected mice. Their increased vulnerability probably results from their failure to use arboreal pathways. Decreased activity may be responsible for the relative advantage of singly infected mice. Previous reports of higher survivorship among mice with a single bot parasite than among uninfected mice, and of lower survivorship among multiply infected mice, may result in part from differential predation rates.
在实验室中，感染了单个 Cuterebra 幼虫的鹿鼠并不比未感染的对照小鼠更容易受到黄鼠狼捕食，并且在某些条件下被捕食的频率可能更低。感染了两个或更多幼虫的小鼠似乎比对照小鼠或仅感染单个幼虫的小鼠更容易受到攻击。它们易受攻击的增加可能是由于它们不使用树栖路径。活动减少可能是仅感染单个幼虫的小鼠具有相对优势的原因。先前关于感染单个肉蝇寄生虫的小鼠比未感染小鼠有更高存活率，以及多重感染小鼠存活率较低的报道，可能部分是由于不同的捕食率造成的。
