Flies are the main bloodsucking ectoparasites of Neotropical bats. The aim of this study was to describe the community of flies on bats from a humid forest enclave, surrounded by the semiarid landscape of the Caatinga domain, in Northeastern Brazil. In addition, we tested the influence of dry and rainy periods on the parasitological indices. Fieldwork was carried out in three anthropized remnants of a humid forest enclave in the Agreste mesoregion of Pernambuco state, Northeastern Brazil. Bats were captured monthly, from August 2018 to July 2019, and the ectoparasites were collected. Overall, 807 bats of 14 species and 11 genera of the families Phyllostomidae (13 spp.) and Vespertilionidae (1 sp.) were captured. Only four bat species had >50 individuals captured, and Carollia perspicillata was the most abundant species (259/807; 32%). Five hundred and seventy-one bat flies from 13 species (11 Streblidae and 2 Nycteribiidae) were collected, of which Trichobius joblingi was the most prevalent fly (197/571; 34.5%). Only the parasitism by T. joblingi was influenced by seasonality, with higher prevalence (P = 0.01) and intensity of infestation (P = 0.02) in the dry season. No lesions associated with parasitism were observed in any of the captured bats. Our results suggest that the bat-fly relationship can be affected in different ways by environmental variables, depending on the species involved. The results of this work contribute to the knowledge about ectoparasites of bats in the Neotropical region, with emphasis on humid forest enclaves, where studies of the host-parasite-environment relationship are scarce.
苍蝇是新热带地区蝙蝠的主要吸血外寄生虫。本研究的目的是描述来自巴西东北部卡廷加地区半干旱景观环绕的湿润森林飞地中蝙蝠身上的苍蝇群落。此外，我们还测试了旱季和雨季对寄生虫学指标的影响。实地调查在巴西东北部伯南布哥州阿格雷斯特中地区一个湿润森林飞地的三个人为改造的残余区域进行。从2018年8月至2019年7月每月捕获蝙蝠，并收集其外寄生虫。总共捕获了14种、11属的807只蝙蝠，隶属于叶口蝠科（13种）和蝙蝠科（1种）。只有4种蝙蝠的捕获个体数超过50只，其中卡氏长舌蝠是数量最多的物种（259/807；32%）。收集到了来自13个物种（11种蝠蝇科和2种蛛蝠科）的571只蝙蝠蝇，其中约氏毛蠓是最常见的苍蝇（197/571；34.5%）。只有约氏毛蠓的寄生受季节性影响，旱季的患病率（P = 0.01）和感染强度（P = 0.02）更高。在任何捕获的蝙蝠中均未观察到与寄生相关的病变。我们的结果表明，蝙蝠与苍蝇的关系会因环境变量而受到不同方式的影响，这取决于所涉及的物种。这项工作的结果有助于了解新热带地区蝙蝠的外寄生虫，重点是湿润森林飞地，该地区关于宿主 - 寄生虫 - 环境关系的研究很少。
