Abstract:The goal of this study was to identify feather mites on Cerrado birds. This study was conducted at Fazenda Água Limpa (FAL), Distrito Federal, Brazil, between January and August 2002. Birds were captured with mist nets and banded. Were sampled 696 birds, belonging to 83 species and 25 bird families of Passeriformes and non-Passeriformes. Feather mites were found on five families: Analgidae, Trouessartiidae, Proctophyllodidae, Avenzoariidae and Psoroptoididae. The present work reports new occurrences of feather mites on captured hosts. The family Proctophyllodidae and the genus Pterodectes were the most prevalent group of feather mites collected. Tyrannidae, Pipridae, Emberizidae and Thraupidae were the bird families with most host numbers, with parasites from three taxa: Trouessartiidae, Proctophyllodidae and Analgidae. Considering the birds captured the prevalence was 44.98%. Trochilidae, Conopophagidae, Furnariidae, Tityridae, Turdidae, Mimidae, Cardinalidae, and Parulidae were the families with major feather mites prevalence (≥50%
Occurence of Dentocarpus silvai silvai, Dusbabek & Cruz, 1966 (Acari: Chirodiscidae) on two molossids (Mammalia: Chiroptera) species in Rio de Janeiro state, Brazil -In 2001 mites from three bats were collected, Molossus ater at Silva Jardim municipality and from Molossus molossus at Rio de Janeiro municipality, both in the Rio de Janeiro state. The mites where identified as Dentocarpus silvai silvai (Acari: Chirodiscidae), this being the first report of this mite species in Brazil.
O primeiro inquérito sobre a fauna de ectoparasitos em rolinha (Columbina talpacoti) é feito no Brasil. As espécies de ectoparasitos encontrados foram: Microlynchia pussila (Speiser, 1902) (Diptera); Columbicola passerinae (Wilson, 1941) and Physconelloides eurysema (Carriker, 1903) (Phthiraptera: Ischnocera); Hohorstiella passerinae Hill & Tull, 1978 (Phthiraptera: Amblycera) and Byersalges talpacoti (Cerný, 1972), Diplaegidia columbigallinae (Cerný, 1972), Nanolichus sp. and Pterophagus lomatus Gaud & Barré, 1992 (Acari: Acaridida), sendo B. talpacoti a espécie de maior prevalência.
