Ticks (Acari: Ixodidae) on wild mammals in the Serra da Canastra National Park and surrounding areas, Minas Gerais, Brazil

Abstract

This researchreports ticks on wild mammals from the Serra da Canastra National Park and surrounding areas, in Minas Gerais state, Brazil. From July 2005 to June 2014, 58 larvae, 133 nymphs and 43 adult ticks were collected in 40 capture events of free-living mammals at the Park and surrounding areas. The tick species Amblyomma ovale Koch, 1844, Amblyomma sculptum Berlese, 1888, Amblyomma tigrinum Koch, 1844, Dermacentor nitens Neumann, 1897, and Rhipicephalus microplus (Canestrini, 1888) were identified on hosts of the order Carnivora. Specimens of Amblyomma pseudoconcolor Aragão, 1908 and A. sculptum were identified on the hosts of the order Xenarthra. We provide the first records of D. nitens and R. microplus ticks parasitizing Lycalopex vetulus, and A. ovale on Leopardus tigrinus in Brazil. The findings of this research indicate the sharing of environment by domestic and wild animals caused by agricultural expansion in the Brazilian landscape.
