ABSTRACT
Mite infestations were observed in 22 of 36 (61%) of Nymphicus hollandicus Kerr, 1792 examined at the Wild Animal Sector of the Veterinary Medicine College - Universidade Federal Fluminense (UFF), Brazil. We examined 177 feather samples from 36 birds for ectosymbiotic arthropods. Nymphicilichus perezae Mironov and Galloway, 2002, was the predominant mite detected, followed by cf. Dubininia sp. Vassilev, 1958 (21.6%). Genus Psittophagus Gaud and Atyeo, 1996 were present in 13.5% of samples. Concurrent infestations of N. perezae and cf. Dubininia sp. occurred in 22.7% of the cockatiels, of N. perezae and Psittophagus sp. in 9.1%, and of N. perezae, cf. Dubininia sp. and Psittophagus sp. in 4.6%. Results were analyzed through a descriptive analysis and the non-parametric Kruskal Wallis test was used to assess the distribution of mites among different regions of birds' bodies. This test showed that remiges primaries (right and left) were the feathers most infested. A few birds (9.1%) had feathers missing in some body regions. Feather-picking behavior was not observed during the clinical examination of the infested cockatiels, and no alterations in feather color were detected in the infestation foci. Due to their specificity to particular places on their hosts' different mite species, appear to live on the same bird without any apparent competition. This work is the first identification of N. perezae in the cockatiel N. hollandicus in Brazil. These are the first records of Psittophagus sp. and cf. Dubininia sp. in cockatiels.
