White-tailed deer (Odocoileus virginianus L.) were evaluated as an alternate host for the cattle fever tick, Boophilus annulatus (Say). The total of adult female ticks recovered and associated reproductive parameters were compared between deer and bovine hosts. Significantly fewer ticks were recovered from deer than from cattle; this was attributed to the grooming behavior of the deer. The mean weight of ticks taken from deer (243.5 mg) was significantly less than that of ticks recovered from cattle (344.5 mg) with about 15% of the ticks from deer prematurely detached. Egg mass weight from the ticks recovered from deer (129.4 mg) was significantly less than that of ticks from cattle (172.1 mg). A significant difference was observed between the percentage hatch of the eggs of ticks from deer (63.1%) and ticks from cattle (76.7%). The index of reproduction was about 20 times greater for the ticks from the cattle than for the ticks from the deer. When the larval progeny of the ticks recovered from deer were reared on cattle, significantly fewer adult females were recovered than when larvae of ticks recovered from cattle were reared on cattle. This indicates a possible reduction in viability. All other parameters were comparable between the two groups. Thus, deer are biologically suitable hosts for B. annulatus, but significantly fewer ticks complete engorgement and those that complete engorgement have reduced fecundity.
白尾鹿（Odocoileus virginianus L.）被评估为牛蜱（Boophilus annulatus (Say)）的替代宿主。比较了从鹿和牛宿主身上采集到的成年雌性蜱的总数以及相关生殖参数。从鹿身上采集到的蜱明显少于从牛身上采集到的；这归因于鹿的梳理行为。从鹿身上采集的蜱的平均重量（243.5毫克）明显低于从牛身上采集的蜱（344.5毫克），约15%从鹿身上采集的蜱过早脱落。从鹿身上采集的蜱所产的卵块重量（129.4毫克）明显低于从牛身上采集的蜱（172.1毫克）。观察到从鹿身上采集的蜱的卵孵化率（63.1%）与从牛身上采集的蜱的卵孵化率（76.7%）之间存在显著差异。牛身上的蜱的繁殖指数比鹿身上的蜱大约高20倍。当将从鹿身上采集的蜱的幼虫后代放在牛身上饲养时，与将从牛身上采集的蜱的幼虫放在牛身上饲养相比，回收的成年雌性蜱明显更少。这表明其生存能力可能降低。两组之间的所有其他参数具有可比性。因此，鹿在生物学上是环形牛蜱的合适宿主，但完全饱血的蜱明显更少，而且那些完全饱血的蜱繁殖力降低。
