Streblidae and Nycteribiidae are ectoparasitic flies exclusive to bats, with an estimated diversity of over 100 species in Brazil. Its distribution and abundance may be influenced by host’s shelter, geographic distribution, behavior, and size. Bat species respond differently to environmental changes, such as changing land use and land cover for cocoa production in the eastern Amazon. We sought to investigate the community of ectoparasite flies (Diptera: Streblidae) on Phyllostominae and Stenodermatinae (Chiroptera: Phyllostomidae) bats and the parasite-host interactions in cacao plantations and natural areas in the Brazilian Amazon. Twenty-two bats were collected, reaching a total of 54 flies. The observed richness was 15 (estimated in 24) species, with Trichobius dugesioides being the most abundant. The cacao plantations showed greater richness, eight species more than the natural ones, however, showing the absence of a specific distribution pattern for each area. This result may be because human interference in cocoa areas are barely perceptible, at least for the bats studied. In addition, the adoption of cabruca-type cocoa plantations can influence the result, as previously shown in the literature.

Bats (Mammalia, Chiroptera) and bat flies (Diptera, Streblidae) found in the largest sandstone cave of Brazil

Bats provide essential ecosystem services and some are cave dependent. Caves favour the association of bats with ectoparasite Diptera, however, they are poorly sampled in the Amazon biome. Here we present the first description of a community of bats and bat flies from the largest sandstone cave in Brazil, the Planaltina cave, located in the municipality of Brasil Novo, state of Pará. Diptera were removed from captured bats and taken to the laboratory for identification. From nine species of bats belonging to four families we recorded 17 species of Diptera, 13 were monoxenous. A possible explanation for the monoxenous parasites collected is that flies have poor survival in unusual hosts. These results are an indicator that the Streblid species are host-specific since even if the hosts take refuge in the same cave, they will not share their parasites. Therefore, the present study provides important information on the parasite-host dynamics in a cave, thus highlighting the importance of cave as are essential shelters for bat species and, despite reported cases of cohabitation, mixed colonies are unlikely to form.
