Domestic filth flies play a significant role in the transmission of nosocomial infections and cause nosocomial myiasis in hospitals worldwide. This descriptive cross-sectional study was conducted in five hospitals of the Hormozgan province, of southern Iran. Adult flies were collected by bottle fly traps. Specimens were pinned and morphologically identified using the relevant keys. Species biodiversity indices including Menhinick (M), Shannon–Wiener (H'), Pielou's Evenness (E), and Simpson's diversity (D) were calculated. Totally 2,298 individuals of 18 species of flies belonging to nine genera and four families were collected. Chrysomya megacephala was the most frequent species (37.3%), followed by Chrysoma albiceps (24.8%), Fannia canicularis (5.1%), Musca domestica (4.8%), Sarcophaga aegyptica (3.7%), and 15 other species (24.4%). Our results show a high diversity and abundance of domestic filth flies in the studied hospitals. Relatively similar data derived from various hospitals in this study can show the uniformity in sanitary conditions of hospitals. On the other hand, estimation of diversity indices alarmed for potential of dominant species in fly communities in hospital environments.
