Fauna de dipteros parasitos de morcegos nas microrregiões do Gurupi e Caxias, estado do Maranhão

Abstract

The order Chiroptera houses diptera belonging to the families Streblidae and Nycteribiidae. The present work aimed to survey the diversity of ectoparasitic bat dipters. The study area comprises micro-region of Gurupi, mesoregion of Oeste Maranhense (Turiaçu, Cândido Mendes, Godofredo Viana, Carutapera) and micro- region of Gurupi (Inhanum Environmental Preservation Area, Caxias) state of Maranhão. Bats were captured with the aid of nets, and the collection of ectoparasites occurred manually, with the aid of tweezers or alcohol-soaked cotton, and stored in individual eppendorfs for later identification. A total of 246 bats were captured, 70 in the Inhanum Environmental Preservation Area and 176 in the Gurupi microregion, belonging to the Phyllostomidae, Vespertilionidae and Molossidae families. A total of 202 dipterans were collected in the two study areas, 137 in the Inhamum Environmental Preservation Area and 65 in the Gurupi micro-region. The genus with the highest frequency was Trichobius. Most of the information obtained was expected to have already been described in the literature in other regions of the country, with no unprecedented infestations occurring in the study areas
