摘要

新热带蝙蝠与其寄生体之间的寄生关系尚不清楚，尽管寄生是影响宿主种群适应性的因素之一。利用流行度、平均强度和平均丰度等指标，研究了不同性别、年龄、体型和生殖状况对黄油松种群寄主关系的影响。93只样本蝙蝠的总患病率为94.6%。研究发现，2种被认为是geoffroroyi的主要寄生物，即clovisi Exastinion (n = 203)和Anastrebla modestini (n = 152)是最多的寄生昆虫，其次是Trichobius sp. (n = 7)， vargasi Periglischrus vargasi (Spinturnicidae) (n = 98)和Spelaeorhynchidae前体Spelaeorhynchus (spelaeorhynidae) (n = 11)。我们记录到，在不同的体外寄生虫特异性关联中，怀孕雌虫的寄生平均丰度和强度高于生殖期雄虫和非生殖期雌虫。寄主年龄和身体状况对寄主寄生指标无明显影响。尽管寄主的寄生率很高，但寄生负荷并不影响寄主的身体状况，但螨虫的侵染率在具有生殖能力的雄蝠中较高，而蝇类的侵染率在具有生殖能力的雌蝠中较高，这表明寄主在不同的生活史阶段会受到不同程度的影响。因此，寄主的生殖活动可能是抵抗寄生虫侵染的不利因素。地下生物学39:63-77 (2021)doi: 10.3897/subtbiol.39.64552 https://subtbiol.pensoft.net版权所有Luísa Lauren Lima Vidal等。这是一篇在知识共享署名许可(CC BY 4.0)条款下发布的开放获取文章，该许可允许在任何媒体上不受限制地使用、分发和复制，前提是要注明原作者和来源。国际地下生物学学会发表的研究论文《地下生物学》同行评议的开放获取期刊

Host-parasite associations in a population of the nectarivorous bat Anoura geoffroyi (Phyllostomidae) in a cave in a Brazilian ferruginous geosystem

Parasitic relationships between Neotropical bats and their ectoparasites are not well known, even though parasitism is one of the factors that can affect the fitness of a host population. This study characterized parasite-host relationships in relation to sex, age, body size and reproductive status in a population of Anoura geoffroyi using the indices of Prevalence, Mean Intensity and Mean Abundance. Total prevalence for 93 sampled bats was 94.6%. Two species of streblid flies that are considered primary parasites of A. geoffroyi, Exastinion clovisi (n = 203) and Anastrebla modestini (n = 152), were the most abundant ectoparasites, followed by Trichobius sp. (n = 7). Two mite species, Periglischrus vargasi (Spinturnicidae) (n = 98) and Spelaeorhynchus praecursor (Spelaeorhynchidae) (n = 11), were also found. We recorded higher mean abundance and intensity of parasitism in pregnant females compared to reproductive males and reproductively inactive females, for different specific associations of ectoparasites. Host age and body condition had no effect on the parasitological indices. Even with high rates of parasitism, parasitic load did not influence host body condition, but infestation rates by mites were higher in reproductive males and higher by flies in reproductive females, showing that ectoparasites can have variable influences between the different stages of the life history of these host bats. Thus, the reproductive activity of the hosts could be an adverse factor for resistance to parasite infestations.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
