Netta peposaca is an anatid endemic to the South American continent and Rhinonyssus rhinolethrum is a rhinonissid mite of wide geographical distribution parasitizing several species of anatids. The association between these organisms has been reported in Argentina; however, the number of birds examined and the parasite indices have not been reported. Thus, the objective of this study was to know the diversity of nasal mites associated with N. peposaca in southern of Brazil and the parasitological indices. The nasal cavities of 30 birds from two locations in Rio Grande do Sul, Brazil, were examined to collect mites. Rhinonyssus rhinolethrum occurred in 16.67% of the birds with an infection intensity of 3-24 mites/host. Infections in male and female hosts showed no significant differences. This study records for the first time R. rhinolethrum and its infection indices in N. peposaca in the southern of Brazil.
佩氏南美雁是南美洲大陆特有的一种鸭科动物，而鼻刺螨是一种广泛分布于地理区域、寄生于多种鸭科动物的鼻刺螨科螨类。在阿根廷已报道过这些生物之间的关联；然而，所检查鸟类的数量以及寄生虫指数尚未见报道。因此，本研究的目的是了解巴西南部与佩氏南美雁相关的鼻螨多样性以及寄生虫学指数。对来自巴西南里奥格兰德州两个地点的30只鸟类的鼻腔进行检查以收集螨类。鼻刺螨在16.67%的鸟类中出现，感染强度为3 - 24只螨/宿主。雄性和雌性宿主的感染情况无显著差异。本研究首次记录了巴西南部佩氏南美雁中鼻刺螨及其感染指数。
