Abstract: The authors collected faeces samples from 16 latrines in five districts of Budapest, to rear flies; the cultures resulted in 3371 specimens representing 23 species (map 1; table 1). The methods of collecting and rearings are discussed. The latrines examined had pits of brick walls or composed of concrete rings, therefore of the damp and dark type. In these latrines members of the genus Fannia breed in the greatest percentage. Fannia scalaris Fabr. represented 59,2 % of the number of individuals, being the dominant species of the dark type latrines. With regard to ethological and feeding habits, the reared Fannia species (F. scalaris, F. incisurata, F. canicularis, F. leucosticta) cannot be qualified, from sanitation and health aspects, as the most dangerous synanthropous flies. Thoracochaeta zosterae (8,8 %) and Eristalis tenax (7,6 %) are, again from the epidemiological point of view, acommunicative species, therefore of a negligible significance. Ophyra and Phorida species were found in 3.8 and 3.7 per cents, respectively, in the latrines. Calliphora uralensis was represented in 2.1 %; this is one of the dangerous synanthropous fly species. Individuals of Lucilla sericata was bred from one latrine; its significance equals that of C. uralensis. The almost complete absence of the Sarcophagids was rather astonishing; pupae were collected from one latrine, but the rearing experiment was unsuccessful. The authors assume that their main breeding sites are the light, dry, primitive type of latrine. On the basis of investigations they point out that the fly assemblage breeding in damp and dark latrines is less dangerous, but only if the latrine is closed by a flapseat to keep out the coprophagous species. It is suggested that in areas lacking a municipial sewage system this type of latrines should be built by force of statute. “Fly-proof” latrines made of prefabricated elements would also be a welcome solution.
