Twenty four percent of 2,643 cottontail rabbits (Sylvilagus floridanus) collected in Virginia from 1949-1975 showed evidence of Cuterebra parasitism. Occurrence was seasonal with greatest prevalence from July to November. Some Oryctolagus cuniculus, S. palustris and one S. transitionalis also showed Cuterebra myiasis. Juvenile rabbits had higher infection rates (28%) than did adult rabbits 14.5%, P less than .001). Juveniles had greater numbers of larvae per host than adults, with means of 2.14 and 1.62, respectively. Larval development sites were in the genital region of most hosts. Twenty flies reared from wild cottontails were identified as C. buccata. Duration of induced infections in Oryctalagus was 30-33 days. Minimal generation time for C. buccata is concluded to be 11 weeks, allowing up to four generations of flies to occur annually in the southern and one generation to occur in the northern distributional limits of this bot fly. Peromyscus hosts were refractory to C. buccata infections. C. buccata fecundity averaged 1316 eggs. Field observations of adult flies are described.
1949年至1975年在弗吉尼亚采集的2643只棉尾兔（佛罗里达棉尾兔）中，24%显示出有黄蝇寄生的迹象。感染情况具有季节性，7月至11月的患病率最高。一些穴兔、沼泽棉尾兔和一只过渡棉尾兔也出现了黄蝇蛆病。幼兔的感染率（28%）高于成年兔（14.5%），P值小于0.001。幼兔体内每只宿主的幼虫数量比成年兔多，平均分别为2.14只和1.62只。大多数宿主的幼虫发育部位在生殖器区域。从野生棉尾兔饲养出的20只苍蝇被鉴定为颊黄蝇。穴兔诱导感染的持续时间为30至33天。得出颊黄蝇的最短世代时间为11周，这使得在该肤蝇分布的南部每年最多可出现四代苍蝇，在北部分布界限每年出现一代。鹿鼠宿主对颊黄蝇感染具有抗性。颊黄蝇的平均繁殖力为1316枚卵。文中描述了对成年苍蝇的野外观察情况。
