在美国东北部的一个林地中，比较了成年硬蜱Spielman、Clifford、Piesman和Corwin取食白尾鹿（Odocoileus virginianus）、浣熊（Procyon lotor）、负鼠（Didelphis virginiana）和家猫的频率。通过结合估计的蜱的数量喂养每种宿主的密度，我们得出了每种宿主的蜱种群的相对贡献。为了比较饱食成功率和繁殖效率，我们对这些宿主上发现的蜱虫进行了称重，并将蜱虫重量与产卵量进行了比较。鹿窝藏每个人最多的女性蜱，虽然鹿比浣熊丰富，他们窝藏94.6%的饲料蜱人口。浣熊、猫和负鼠分别为3.6%、1.6%和0.2%的成年蜱提供了血餐。蜱虫在猫和浣熊身上比在鹿身上更成功地充血，并且产蛋量与从猫和鹿身上收集的雌性蜱虫的重量呈线性相关。虽然这些蜱虫在其他宿主身上更容易膨胀，但绝大多数的卵是由以鹿为食的蜱虫产生的。我们的结论是，在这个网站上，鹿的丰度在很大程度上决定了丰富的I。dammini，莱姆病的媒介。
The frequencies with which adult Ixodes dammini Spielman, Clifford, Piesman and Corwin feed upon white-tailed deer (Odocoileus virginianus), raccoons (Procyon lotor), opossums (Didelphis virginiana), and domestic cats were compared in a wooded site in northeastern United States. By combining estimates of the quantity of ticks feeding on each host species with host densities, we derived the relative contribution made by each kind of host to the feeding of the tick population. To compare engorgement success and reproductive efficacy, we weighed ticks found on these hosts and compared tick weights with the quantity of eggs produced. Deer harbored the most female ticks per individual and, although deer were less abundant than raccoons, they harbored 94.6% of the feeding tick population. Raccoons, cats, and opossums, respectively, provided blood meals to 3.6, 1.6, and 0.2% of feeding adult ticks. Ticks engorged more successfully on cats and raccoons than on deer, and egg production correlated linearly with weight of female ticks collected from both cats and deer. Although these ticks engorged better on other hosts, the vast majority of eggs resulted from ticks that had fed on deer. We conclude that, in this site, the abundance of deer largely determines the abundance of I. dammini, the vector of the agent of Lyme disease.
