Carrapatos (Acari: Ixodidae) capturados na Reserva Natural da Vale do Rio Doce, Linhares, Espírito Santo

Abstract

We confirm, after decades without new registers, the occurrence of the ticks Amblyomma obolongoguttatum Koch, 1844, A. brasiliense Aragão, 1908, and A. humerale Koch, 1844 in the State of Espírito Santo, Brazil, besides the first record of A. naponense (Packard, 1869) in this state.

Parasitism by Amblyomma humerale (Acari: Ixodidae) on Chelonoidis denticulatus (Testudines: Testudinidae) in the Atlantic Forest

“…In the previous study in RNV, 43 adult ticks (35 males and eight females) were found on two tortoises, with an average of 21.50 ticks per specimen (Ogrzewalska et al, 2007). Unlike the work of Ogrzewalska et al (2007), the average infestation rate observed in the present study was almost 1.9 times lower. In the previous work, the collections were carried out at the beginning of April 2006 (sampling at a single time), while the collections carried out in the present work occurred at different times and seasons.…”

“…Another previous record in Espírito Santo (municipality of Pinheiros, in the extreme north of the state) included reporting of Rickettsia amblyommatis (published as Rickettsia amblyommii) in this tick species for the first time (Acosta et al, 2016). In the previous study in RNV, 43 adult ticks (35 males and eight females) were found on two tortoises, with an average of 21.50 ticks per specimen (Ogrzewalska et al, 2007). Unlike the work of Ogrzewalska et al (2007), the average infestation rate observed in the present study was almost 1.9 times lower.…”

“…The tick Amblyomma humerale Koch, 1844 is considered to be an endemic species in South America, and its presence has been reported in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Suriname, Trinidad and Tobago and Venezuela (Labruna et al, 2002a;Morais et al, 2017). In Brazil, this species can be found in the Amazon region (Labruna et al, 2002a(Labruna et al, , 2004Gianizella et al, 2018), transition zone between the Cerrado (the Brazilian savanna) and Amazon rainforest (Morais et al, 2017) and Atlantic Forest (Sinkoc & Brum, 1997;Ogrzewalska et al, 2007).…”

“…Parasitism by adult A. humerale has commonly been associated with terrestrial turtles (Testudines, Testudinidae), such as Chelonoidis denticulatus (Linnaeus, 1766) (yellow-footed tortoise) and Chelonoidis carbonarius (Spix, 1824) (red-footed tortoise) (Labruna et al, 2002a;Ogrzewalska et al, 2007;Guglielmone et al, 2014;Morais et al, 2017;Martins et al, 2020). Other reports have described parasitism of adult A. humerale on the toad Rhinella arenarum (Hensel, 1867) (previously Bufo arenarum -Anura, Bufonidae; Sinkoc & Brum, 1997) and, under laboratory conditions, on Trachemys scripta (Wied-Neuwied, 1839) (red-eared slider -Testudines, Emydidae; Martins et al, 2020).…”
