Item Carios fonsecai sp. nov. (Acari, Argasidae), a bat tick from the central-western region of Brazil(Acta Parasitologica, 2009) Labruna, Marcelo B; Venzal, José M.Item Description of a New Species of Bat-Associated Argasid Tick (Acari: Argasidae) from Brazil(Journal of Parasitology, 2012) Torres, Filipe Dantas; Venzal, José M.; Bernardi, Leopoldo F. O.; Ferreira, Rodrigo Lopes; Onofrio, Valéria C.; Marcili, Arlei; Bermúdez, Sergio E.; Ribeiro, Alberto F.; Battesti, Darci M. Barros; Labruna, Marcelo B.- Ecology of Antricola ticks in a bat cave in north-eastern Brazil(2020-09-12) Barbier, Eder; Bernard, Enrico; Dantas‑Torres, FilipeArgasid 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 dec-ades, with a number of new species described in various zoogeographical regions. None-theless, 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. Fur-ther 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.
Item New records of rare Ornithodoros (Acari: Argasidae) species in caves of the Brazilian Amazon(Persian Journal of Acarology, 2012) Simões, Matheus Henrique; Bernardi, Leopoldo Ferreira de Oliveira; Ogrzewalska, Maria; Labruna, Marcelo Bahia; Ferreira, Rodrigo LopesItem Spider preying on ticks in a Brazilian cave(Speleobiology Notes, 2010) Bernardi, Leopoldo Ferreira de Oliveira; Dantas-Torres, Filipe; Labruna, Marcelo Bahia; Ferreira, Rodrigo LopesItem The Ornithodoros capensis group (Acari: Argasidae): a morphorlogical diagnosis and molecular characterization of O. capensis sensu stricto from Queimada Grande Island, Brazil.(Systematic & Applied Acarology, 2017) MUÑOZ-LEAL, SEBASTIÁN; DIAS, RICARDO A.; ABRAHÃO, CARLOS R.; LABRUNA, MARCELO B.Ornithodoros capensis sensu lato (s. l.) is a worldwide-distributed group of soft ticks that parasitize birds in insular and continental lands. It is currently composed of 11 morphologically closely related species. Several viral and bacterial pathogens, and particularly Coxiella-like endosymbiont organisms have been described coexisting with ticks of this group. Since it last report in 1983, the presence of O. capensis s. l. in Brazil has remained undocumented. By a morphological analysis of larvae and a molecular characterization of ticks and Coxiella genes we describe for the first time O. capensis sensu stricto in Brazil from specimens collected on Queimada Grande Island, in São Paulo stateItem Ticks (Ixodida) associated with bats (Chiroptera): an updated list with new records for Brazil(2023-08-19) Lourenço, Elizabete Captivo; Famadas, Kátia Maria; Gomes, Luiz Antonio Costa; Bergallo, Helena GodoyBats harbor diverse groups of ectoparasites, such as insects and mites like ticks (Ixodida). Some species of ticks with records for bats and humans have already been reported with the occurrence of pathogens. This research article aims to document new geographical and host records of ticks infesting bats in Rio de Janeiro state, Southeastern Brazil, and provides a list of tick species associated with bats in Brazil. We counted 12 argasid ticks and five ixodid ticks associated with six individuals of bats. Larvae of Amblyomma sp., Ixodes sp., Ornithodoros sp., and Ornithodoros hasei and one nymph of Amblyomma sculptum parasitizing Artibeus obscurus, Phyllostomus hastatus, Micronycteris sp., Molossus fluminensis, and Carollia perspicillata in different localities of Rio de Janeiro state were studied. We carried out a systematic review with the descriptors: tick bat Brazil. We considered data from 42 articles in the systematic review. We compiled eleven records of Ixodidae, and 160 records of Argasidae. Ornithodoros cavernicolous were the most recorded tick species. Overall, we registered 171 tick–bat or roost–bat associations with 85 records of these infesting bats. The review also shows the occurrence of tick species associated with bats, and we present new records on ticks parasitizing bats in Brazil.
