Parasites have been investigated for some New World primates; however, very little is known about ectoparasites and specifically fur mites. In this study, Alouatta palliata, Cebus capucinus, Saimiri oerstedii, and Ateles geoffroyi monkeys from different areas of Costa Rica were searched for fur mites. A total of 276 monkeys were evaluated, and 51 of them were positive for mites of the family Atopomelidae. Listrocarpus alouattae was identified on 22.3% of A. palliata; Listrocarpus capucinus on 12.8% of C. capucinus; and Listrocarpus costaricensis on 36.8% of S. oerstedii; No fur mites were found on A. geoffroyi. Sex was not considered a determinant of mite infestation, but prevalence was significantly higher in the Central Volcanic Mountain Range Conservation Area for L. alouattae (p=0.01) and in the Central Pacific Conservation Area for L. capucinus (p=0.002). These primate fur mites are highly host-specific. Differences in the geographical distribution may be due to monkey behavior and history, as well as to environmental conditions.
已经对一些新大陆灵长类动物的寄生虫进行了调查；然而，人们对体外寄生虫，特别是皮毛螨的了解非常少。在这项研究中，对来自哥斯达黎加不同地区的白喉卷尾猴、褐卷尾猴、黑冠松鼠猴和 Geoffroy 蜘蛛猴进行了皮毛螨搜索。总共评估了276只猴子，其中51只对顶叶螨科的螨虫呈阳性。在22.3%的白喉卷尾猴身上发现了阿氏列果螨；在12.8%的褐卷尾猴身上发现了卷尾猴列果螨；在36.8%的黑冠松鼠猴身上发现了哥斯达黎加列果螨；在 Geoffroy 蜘蛛猴身上未发现皮毛螨。性别不是螨虫感染的决定因素，但对于阿氏列果螨，在中央火山山脉保护区的感染率显著更高（p=0.01），对于卷尾猴列果螨，在中太平洋保护区的感染率显著更高（p=0.002）。这些灵长类动物的皮毛螨具有高度的宿主特异性。地理分布的差异可能归因于猴子的行为和历史，以及环境条件。
