Species composition and breeding sites of fly communities (Diptera) in caged-layer houses in Hungary Dr. Róbert FARKAS and Dr. László PAPP Department of Parasitology and Zoology, University of Veterinary Science, Budapest, — Zoological Department, Hungarian Natural History Museum, Budapest, Hungary "Species composition and breeding sites of fly communities (Diptera) in cagedlayer houses in Hungary" - Farkas, R. - Papp, L. - Parasit, hung., 22_: 93-98. 1989. ABSTRACT. This is the first dipterological survey to reveal the species composition and breeding sites of fly communities, in poultry houses in Hungary . In July, August and October 1987, manure and feed refuse samples were taken in a caged-layer house of a co-operative farm in the outskirts of Budapest. Flies were reared from the samples in laboratory (n=9275). Among the representatives of the 15 species reared, the housefly, the primary pest in poultry houses, was found in low numbers as a consequence of prédation by the larvae of Hydrotaea ignava (Harris, 1780). A larger number of Fannia canicularis L. was reared and also Stomoxys calcitrans L. was found. A drosophilid species, Drosophila repleta Woll. was reared in the highest number and studies are proposed to evaluate its veterinary importance. The primary breeding sites in the house are in the accumulated manure and feed refuses on collecting plates beneath both ends of the upper tiers. Areas beneath and near the feed containers (outside the house) are also important breeding sites. No differences were found between the July and August samples (518 specimens of 8 spp. in 11 samples vs. 405 specimens of 14 spp. in 15 sam* pies, the latter with some accessorial species). The samples from October (8352 specimens of 5 spp. in 13 samples) were predominated by Drosophila re pleta Woll. KEY WORDS. Diptera, filth flies, poultry, breeding sites, species composition, Hungary . In modern production systems the accumulation of large amount of manure and microclimatic as well as feed opportunities have produced excellent conditions for the breeding of filth flies, some of which are major pests of livestock and poultry. In order to estimate their actual veterinary and economic importance and to improve control methods, the species composition and the relative abundance of the species in fly communities have to be surveyed In the different production systems. This survey can be conducted effectively through a search of their breeding sites.
