External and gastrointestinal parasites of the rufous-collared sparrow Zonotrichia capensis (Passeriformes, Emberizidae) in Chile / Parasitas gastrointestinais e externos do tico-tico Zonotrichia capensis (Passeriformes, Emberizidae) do Chile

ABSTRACT

Abstract A total of 277 rufous-collared sparrows, Zonotrichia capensis Müller, 1776 (Emberizidae), were examined for external parasites. The birds were captured using mist nets in seven locations in northern and central Chile. Additionally, seven carcasses from central Chile (the Biobío region) were necropsied to evaluate the presence of endoparasite infection. Ectoparasites were found on 35.8% (99/277) of the examined birds and they were represented by the following arthropods feather mites Amerodectes zonotrichiae Mironov and González-Acuña, 2014 (Analgoidea Proctophyllodidae), Proctophyllodes polyxenus Atyeo and Braasch, 1966 (Analgoidea Proctophyllodidae), and Trouessartia capensis Berla, 1959 (Analgoidea Trouessartiidae); a louse Philopterus sp. (Phthiraptera Ischnocera); and ticks Amblyomma tigrinum Koch, 1844 (Acari Ixodidae) and Ixodes auritulus Neumann, 1904 (Acari Ixodidae). Two of the seven necropsied carcasses were infected with the acanthocephalan Mediorhynchus papillosus Van Cleave, 1916 (Gigantorhynchida Gigantorhynchidae). To our knowledge, this study reports P. polyxenus, Philopterus sp., A. tigrinum, and M. papillosus for the first time for Z. capensis and expands the distributional range for T. capensis to Chile.

RESUMO

Resumo Um total de 277 tico-tico Zonotrichia capensis Müller, 1776 (Emberizidae) foram examinados em busca de ectoparasitos. As aves foram capturadas com redes em sete localidades do norte e centro do Chile. Além disso, sete carcaças do centro Chile (Região de Biobío) foram examinadas para avaliar a infecção por endoparasitos. Ectoparasitos foram encontrados em 35,8% (99/277) das aves examinadas com a identificação dos ácaros Amerodectes zonotrichiae Mironov and González-Acuña, 2014 (Analgoidea Proctophyllodidae), Proctophyllodes polyxenus Atyeo and Braasch, 1966 (Analgoidea Proctophyllodidae) e Trouessartia capensis Berla, 1959 (Analgoidea Trouessartiidae), piolho Philopterus sp. (Phthiraptera Ischnocera) e carrapatos Amblyomma tigrinum Koch, 1844 (Acari Ixodidea) e Ixodes auritulus Neumann, 1904 (Acari Ixodidea). Duas das sete carcaças examinadas foram infectadas com o Acantocephala Mediorhynchus papillosus Van Cleave, 1916 (Gigantorhynchida Gigantorhynchidae). Para o nosso conhecimento, este é o primeiro estudo para descrever P. polyxenus, Philopterus sp., A. tigrinum e M. papillosus em Z. capensis e expande a distribuição de T. capensis ao Chile.
