First record of Philornis glaucinis Dodge & Aitken, 1968 (Diptera: Muscidae) in Thalurania glaucopis Gmelin, 1788 (Aves: Trochilidae)

Abstract

From the groups causing myiasis, the genus Philornis Meinert, 1890 appears as the only representative of the family Muscidae, obligatorily associated with birds. Thus, the aim of this work was to report the occurrence of Philornis in Thalurania glaucopis (Trochilidae). Two parasitized nestlings of T. glaucopis were encountered in May of 2008, in an area with a high degree of degradation in the municipal district of Petrópolis, Rio de Janeiro. A total of 11 larvae were located intradermically in the regions of the head and neck. The larvae were removed using tweezers and placed in a plastic container with sawdust, in order to await the emergence of the adult. Only seven larvae completed metamorphosis and reached the adult stage, being identified as Philornis glaucinis. This study presented the first record of P. glaucinis in the state of Rio de Janeiro and also the first occurrence of this parasite in nestlings of T. glaucopis.
