In total, 6,486 rodents representing 3 families (Muridae, Heteromyidae, and Sciuridae) and 24 species were trapped May through August of 1991 through 1994. Of these, only the white-throated woodrat. Neotoma albigula Hartley; piñon mouse, Peromyscus truei Shufeldt; and white-footed mouse, P. leucopus Rafinesque, were infested with Cuterebra Clark larvae. Of the 594 N. albigula that were captured 103 (17.3%) were infested with 139 Cuterebra larvae with all infestations occurring in the throat region. N. albigula infestations were observed in 4 of 5 habitats sampled. The highest prevalence of infestation occurred during May-June (27.2%) versus July-August (9.1%) and in males (25.2%) versus females (18.3%). Prevalence of infestation was not significantly different between animals from the mark-release webs versus removal webs or adults versus juveniles. Also, there was no correlation between relative density of N. albigula and prevalence of infestation. Fifteen adults were reared from puparia and identified as C. austeni Sabrosky. Of 716 P. truei captured, 22 (3.1%) were infested with a total of 25 Cuterebra larvae with all infestations occurring in the scapular region. Although P. truei were captured in all 5 habitats, they were only infested in the piñon-juniper habitat: the highest prevalence of infestation occurred during July-August (10.9%) versus May-June (3.3%). Prevalence of infestation was not significantly different between animals from mark-release webs versus removal webs, males versus females, or adults versus juveniles. As in the N. albigula, there was no correlation between relative density of P. truei and prevalence of infestation. The adult reared from a puparium was identified as C. neomexicana Sabrosky. Of the 310 P. leucopus captured, only 3 (1%) were infested with Cuterebra larvae.
1991年至1994年的5月至8月期间，共捕获了6486只啮齿动物，分属于3个科（鼠科、更格卢鼠科和松鼠科），24个物种。其中，只有白喉林鼠（Neotoma albigula Hartley）、矮松小鼠（Peromyscus truei Shufeldt）和白足鼠（P. leucopus Rafinesque）感染了 Cuterebra Clark 幼虫。在捕获的594只白喉林鼠中，有103只（17.3%）感染了139只 Cuterebra 幼虫，所有感染均发生在喉部区域。在采样的5个栖息地中，有4个观察到白喉林鼠感染情况。感染率最高出现在5月至6月（27.2%），而7月至8月为（9.1%），雄性（25.2%）高于雌性（18.3%）。标记释放网捕获的动物与移除网捕获的动物之间、成年动物与幼年动物之间的感染率没有显著差异。此外，白喉林鼠的相对密度与感染率之间没有相关性。从蛹中羽化出15只成虫，鉴定为奥氏 Cuterebra（C. austeni Sabrosky）。在捕获的716只矮松小鼠中，有22只（3.1%）感染了总共25只 Cuterebra 幼虫，所有感染均发生在肩胛区域。尽管矮松小鼠在所有5个栖息地都有捕获，但它们只在矮松-杜松栖息地感染：感染率最高出现在7月至8月（10.9%），而5月至6月为（3.3%）。标记释放网捕获的动物与移除网捕获的动物之间、雄性与雌性之间、成年动物与幼年动物之间的感染率没有显著差异。与白喉林鼠一样，矮松小鼠的相对密度与感染率之间没有相关性。从蛹中羽化出的成虫鉴定为新墨西哥 Cuterebra（C. neomexicana Sabrosky）。在捕获的310只白足鼠中，只有3只（1%）感染了 Cuterebra 幼虫。
