A comparative study of feeding and host preference was made among immatures of Ixodes dammini Spielman, Clifford, Piesman & Corwin, I. scapularis Say, and I. pacificus Cooley & Kohls, using white laboratory mice, Eumeces lizards, and chickens (3-4 d old) as hosts. Larval feeding of each species when placed on hosts was greater (P less than 0.05) on mice than on chickens and lizards and higher on lizards than on chickens (P less than 0.05). When larvae of the three species were given a choice between mouse and lizard and mouse and chicken, they preferred mice (except no statistical difference was found between mice and chickens for I. pacificus larvae). When given a choice between lizard and chicken, no significant difference in host preference was seen. Nymphs of I. dammini, I. scapularis, and I. pacificus displayed no statistical difference in feeding ability between mice and lizards when placed on these hosts, but more ticks fed on mice and lizards than on chickens. Nymphs of all three species also showed no preference between mice and lizards but preferred either of these hosts to chickens (however, no statistical difference was found between mice and chickens for I. dammini nymphs or between lizards and chickens for I. pacificus nymphs).
以白色实验小鼠、石龙子蜥蜴和（3 - 4日龄的）雏鸡作为宿主，对达氏硬蜱（Ixodes dammini Spielman、Clifford、Piesman & Corwin）、肩突硬蜱（I. scapularis Say）和太平洋硬蜱（I. pacificus Cooley & Kohls）的未成熟个体进行了摄食情况和宿主偏好的比较研究。当将每种硬蜱的幼虫置于宿主上时，其在小鼠上的摄食量比在雏鸡和蜥蜴上更大（P < 0.05），在蜥蜴上的摄食量高于雏鸡（P < 0.05）。当让这三种硬蜱的幼虫在小鼠与蜥蜴、小鼠与雏鸡之间进行选择时，它们更喜欢小鼠（太平洋硬蜱幼虫在小鼠和雏鸡之间未发现统计学差异除外）。当在蜥蜴和雏鸡之间进行选择时，未观察到宿主偏好上的显著差异。将达氏硬蜱、肩突硬蜱和太平洋硬蜱的若虫置于小鼠和蜥蜴上时，它们在摄食能力上没有统计学差异，但在小鼠和蜥蜴上摄食的蜱比在雏鸡上更多。这三种硬蜱的若虫在小鼠和蜥蜴之间也没有偏好，但相比于雏鸡，它们更喜欢这两种宿主中的任何一种（然而，达氏硬蜱若虫在小鼠和雏鸡之间以及太平洋硬蜱若虫在蜥蜴和雏鸡之间均未发现统计学差异）。
