Abstract
This study aims to record mites associated with the respiratory system of Columba livia Gmelin, 1789, including data of parasitological indices and of coinfections in southern Brazil. Two hundred and two specimens of C. livia were collected in the urban area in Pelotas, Rio Grande do Sul (RS) state, Brazil. Fifty-six (27.7%) birds were parasitized by Rhinonyssidae and Ereynetidae mites. Tinaminyssus columbae (Crossley, 1950) and Tinaminyssus melloi (Castro, 1948) (Rhinonyssidae) were found in nasal cavities and tracheae of the birds. Trispeleognathus striatus (Crossley, 1952) (Ereynetidae) was found in hosts’ nasal cavities. The prevalence of Rhinonyssidae mites (25.2%) was significantly higher than obtained for Ereynetidae (5.9%). Coinfections only occurred in nasal cavities of 8 (3.96%) birds. This study records for the first time T. columbae and Trispeleognathus striatus parasitizing C. livia in Brazil. In addition, mite infection indices and coinfections of Rhinonyssidae and Ereynetidae mites in this Columbidae species are recorded.
