Botfly infestation was analyzed in 1319 small mammals from varied habitats and elevations in upland Virginia, 1972-1974. Adult Cuterebra fontinella were reared from bots infesting the woodmouse (Peromyscus leucopus). Of 651 woodmice, 199 (30.6%) were infested at least once. The season of bot infestation extended from May through November of all years, with peak prevalence (mean 42.2%) in August. Infestation in woodmice was general over a 2000 km2 study area during peak months. Significantly greater prevalence (P less than 0.001) was seen in forested and brushy habitat (39.9%) compared with old fields (2.6%). Higher prevalence (P less than 0.01) was found in males than in females, and in postjuveniles compared to adults. Greatest overall prevalence (39.1%) was in postjuvenile males. Most warble sites (98%) were inguinal, and observations suggested that many infested adults were non-reproductive. Mean burden (1.27) was independent of host age, sex, habitat, and month of capture. Multi-infestations occurred in 23% of the affected mice; maximum burden was six bots. Botflies were absent or negligible in sympatric deermice (P. maniculatus) and twelve other species of rodents and shrews.
1972年至1974年期间，对弗吉尼亚高地不同栖息地和海拔高度的1319只小型哺乳动物的肤蝇感染情况进行了分析。从感染家鼠（白足鼠）的蝇蛆中培育出成年的黄猩猩肤蝇。在651只家鼠中，199只（30.6%）至少感染过一次。所有年份的蝇蛆感染季节从5月持续到11月，8月的感染率最高（平均为42.2%）。在感染高峰期的几个月里，家鼠在2000平方公里的研究区域内普遍感染。与旧耕地（2.6%）相比，在森林和灌木丛栖息地（39.9%）观察到的感染率显著更高（P<0.001）。雄性家鼠的感染率高于雌性（P<0.01），幼年后期家鼠的感染率高于成年家鼠。总体感染率最高（39.1%）的是幼年后期雄性家鼠。大多数瘤肿部位（98%）在腹股沟，观察表明许多受感染的成年家鼠没有繁殖能力。平均感染数量（1.27）与宿主的年龄、性别、栖息地和捕获月份无关。23%的受影响家鼠出现多重感染；最大感染数量为6只蝇蛆。在同域分布的鹿鼠（北美鹿鼠）以及其他12种啮齿动物和鼩鼱中，肤蝇不存在或数量可忽略不计。
