Purpose

Neotropical bats are infested by multiple ectoparasites (like bat fly and mite species) and investigations on these invertebrates on their hosts are crucial to better understand the ectoparasite-ectoparasite and ectoparasite-host associations. The goal of this study was to report ectoparasites species (bat flies and mites) on bats, emphasizing ectoparasite co-occurrences and host-ectoparasite associations. We also test if there is relationship between bat flies and mites on their hosts.

Methods

This study occurred twice a month from September 2011 to September 2012 in an Atlantic Forest remnant in Rio de Janeiro State, Brazil. Spearman correlation was used to test relationship between bat flies and mites.

Results

We found 27 species of ectoparasites on 13 species of bats. Ectoparasites belonged to the bat fly families Streblidae and Nycteribiidae, and the mite families Spinturnicidae, Macronyssidae, Sarcoptidae, and Trombiculidae. Streblid-streblid association was more frequent, but we also recorded streblid-spinturnicid, streblid-sarcoptid and spinturnicid-spinturnicid associations. The abundance of spinturnicid species was negatively related to the abundance of streblid species. We record the first occurrence of Strebla chrotopteri associated with Chrotopterus auritus, Periglischrus paracutisternus associated with Trachops cirrhosus and Basilia juquiensis associated with Myotis riparius for Rio de Janeiro State.

Conclusion

There were several co-occurrences between different taxa and between species of the same family. These results show the importance of the integrated taxonomic record. The negative interspecific interactions between spinturnicid and streblid may affect distributions, structuring ectoparasite communities on hosts.

在巴西东南部大西洋森林的残余物中，寄生虫（昆虫纲和蛛形纲）在蝙蝠（鳞翅目）上同时存在。

目的

新热带蝙蝠受多种外寄生虫（如蝙蝠蝇和螨虫）的侵袭，对其寄主上这些无脊椎动物的调查对于更好地了解外寄生虫-外寄生虫和外寄生虫-宿主之间的联系至关重要。这项研究的目的是报告蝙蝠上的外寄生物种类（蝙蝠的苍蝇和螨虫），强调外寄生物的共现和宿主-外寄生物的联系。我们还测试了它们的宿主上的蝙蝠蝇和螨虫之间是否存在关系。

方法

这项研究从2011年9月至2012年9月，每月两次在巴西里约热内卢州的大西洋森林遗迹中进行。Spearman相关性用于测试蝙蝠蝇和螨之间的关系。

结果

我们在13种蝙蝠上发现了27种外寄生虫。体外寄生虫属于蝙蝠蝇科Streblidae和Nycteribiidae，螨虫科Spinturnicidae，Macronyssidae，Sarcoptidae和Trombiculidae。Streblid-streblid关联更为频繁，但我们也记录了streblid-spinturnicid，streblid-sarcoptid和spinturnicid-spinturnicid关联。旋转节肢动物物种的丰富度与硬壳动物物种的丰富度负相关。我们记录的第一次出现Strebla chrotopteri关联Chrotopterus auritus，Periglischrus paracutisternus关联Trachops cirrhosus和Basilia juquiensis关联鼠耳蝠riparius 为里约热内卢州。

结论

在不同的分类单元之间以及同一家族的物种之间存在几种同时出现的现象。这些结果表明了综合生物分类记录的重要性。旋转棘突和斯特雷伯利德之间的负种间相互作用可能影响分布，从而在寄主上构造外寄生虫群落。
