Parasites significantly influence ecosystems by controlling host populations and spreading diseases, thereby impacting ecological balances. In the Neotropics, hematophagous bat flies and mites are common ectoparasites of bats. The state of Mato Grosso, Brazil, hosts a diverse bat fauna across its Amazon Forest, Cerrado, and Pantanal habitats. We described bat flies and wing mites associated with bats in an urban area in the Amazon-Cerrado transition. Despite the expected diversity of bat in the study area, we expect to find a low number of ectoparasites species, as urban areas are typically associated with reduced parasite diversity. Bats were captured using mist nets, and ectoparasites collected manually or with tweezers and identified under the stereomicroscope. We found 10 species of ectoparasites (seven bat flies and three wingmites) from 181 bats across 22 species. The study found low ectoparasite diversity, possibly due to the small number of bats captured or the constraints found in the urban environment. Most observed bat-ectoparasite associations were consistent with previous studies, but some unexpected associations suggested possible contamination or transient relationships. This research fills a gap in the knowledge of bat ectoparasites in Mato Grosso, contributing to understanding bat-ectoparasite dynamics in diverse habitats.
寄生虫通过控制宿主数量和传播疾病对生态系统产生重大影响，从而影响生态平衡。在新热带地区，吸血蝠蝇和螨虫是蝙蝠常见的体外寄生虫。巴西马托格罗索州在其亚马逊森林、塞拉多和潘塔纳尔湿地栖息地拥有多样的蝙蝠动物群。我们描述了亚马逊-塞拉多过渡区一个城市地区与蝙蝠相关的蝠蝇和翼螨。尽管研究区域内蝙蝠种类预计具有多样性，但由于城市地区通常与寄生虫多样性降低相关，我们预计发现的体外寄生虫种类数量较少。使用雾网捕获蝙蝠，并手动或用镊子收集体外寄生虫，然后在体视显微镜下进行鉴定。我们从22个物种的181只蝙蝠身上发现了10种体外寄生虫（7种蝠蝇和3种翼螨）。该研究发现体外寄生虫多样性较低，这可能是由于捕获的蝙蝠数量较少或城市环境中存在的限制因素所致。大多数观察到 的蝙蝠与体外寄生虫的关联与先前的研究一致，但一些意外的关联表明可能存在污染或短暂关系。这项研究填补了马托格罗索州蝙蝠体外寄生虫知识的空白，有助于理解不同栖息地中蝙蝠与体外寄生虫的动态关系。
