Prevalence and intensity of Streblidae in bats from a Neotropical savanna region in Brazil.

Bats of the family Phyllostomidae are common hosts to streblids known as bat flies. Here, we discuss the component community, prevalence and intensity of infection with species of Streblidae on an assemblage of phyllostomid bats in the Cafuringa Environmental Protection Area (APA Cafuringa) in the core area of the Cerrado in Central Brazil. A total of 1 841 streblid individuals of 24 species occurred on 752 bats of 14 species. Ten species of streblids infected Glossophaga soricina (Pallas), whereas seven or fewer streblid species infected the other bat species. Nine bat fly species presented a prevalence of more than 50%, whereas some differences in the abundance of bat flies among hosts were observed. Strebla wiedemanni Kolenati, 1856 and Trichobius furmani Wenzel, 1966 were more host-specific compared to the other streblids, and they occurred in greater abundance on their preferred hosts. Trichobius uniformis Curran, 1935 and Strebla mirabilis (Waterhouse, 1879) were the least host-specific, occurring on five and six hosts, respectively.
