Argasid ticks are a diverse group of acarines that parasitize numerous vertebrate hosts. Along with birds, bats serve as hosts for several argasid ticks, which are commonly found in bat caves. Argasid ticks have regained attention from tick taxonomists in recent decades, with a number of new species described in various zoogeographical regions. Nonetheless, studies on their ecology are still scarce. We conducted a 1-year longitudinal study to assess the presence of argasid ticks in a bat cave in the drylands of north-eastern Brazil and evaluate their possible response to abiotic factors. From July 2014 to June 2015, 490 ticks were collected (272 nymphs, 169 males and 49 females) in a cave chamber hosting a large colony of Pteronotus spp. bats, being relatively more frequent from July to December 2014. Adults were identified as Antricola guglielmonei, whereas nymphs were assigned to the genus Antricola. Almost all ticks (98%) were collected on the cave walls. Only 2% were on the ceiling and, surprisingly, no specimens were found on the floor and/or guano. Adults were usually clustered in the crevices and little mobile, whereas nymphs were dispersed and more active, moving over the walls or ceiling of the cave. Although present in most of the studied period, there was a significantly negative correlation between tick abundance and relatively humidity, and A. guglielmonei was more frequent during the dry season. Moreover, there was no evident correlation between the abundance of ticks and bats. Further long-term studies will be able to verify whether this pattern is repeated over time, and even whether other variables can influence the population dynamics of A. guglielmonei.

杀虫gas是一群寄生于许多脊椎动物宿主中的螨类。蝙蝠与鸟类一样，也充当着多个Argasid壁虱的寄主，这在蝙蝠洞中很常见。近年来，类tick已经引起gas类分类学家的关注，在各个动物地理区域都描述了许多新物种。然而，关于它们的生态学的研究仍然很少。我们进行了为期1年的纵向研究，以评估巴西东北部干旱地区蝙蝠洞中是否存在类gas虫，并评估其对非生物因子的可能反应。从2014年7月到2015年6月，在一个收容大型翼龙种群的洞穴室内收集了490滴s（272仙女，169例雄性和49例雌性）spp。蝙蝠，从2014年7月至2014年12月相对更频繁。成虫被定为古格氏Antricola，而若虫被归为Antricola属。几乎所有壁虱（98％）都收集在洞穴壁上。天花板上只有2％，令人惊讶的是在地板和/或鸟粪上没有发现标本。成虫通常聚集在缝隙中，很少活动，而若虫则分散且更活跃，在洞穴的墙壁或天花板上移动。尽管存在于大部分研究时期，但tick丰度和相对湿度与A之间存在显着的负相关。古列尔莫内在旱季更频繁。而且，s和蝙蝠的数量之间没有明显的相关性。进一步的长期研究将能够验证这种模式是否随着时间的推移而重复，甚至其他变量是否也会影响A的种群动态。古列尔蒙内。
