Blowflies of the Genera Calliphora, Lucilia and Protophormia (Diptera, Calliphoridae) in South-Moravian Urban and Rural Areas with Respect to Lucilia bufonivora Moniez, 1876

The occurrence of blowflies with public health importance (four species of the genus Calliphora Robineau-Desvoidy, 1830, nine species of the genus Lucilia Robineau-Desvoidy, 1830 and one species of the genus Protophormia Townsend, 1908) was studied in the city of Brno and a village Ketkovice near Brno.A total of 2781 imagoes (1926 from Brno and 855 from Ketkovice) were obtained from both study areas by sweeping, trapping or rearing from eggs.Calliphora uralensis, C. vicina, C. vomitoria, Lucilia ampullacea, L. bufonivora, L. caesar, L. illustris, L. pilosiventris, L. regalis, L. sericata, L. silvarum and Protophormia terraenovae were found in both study areas.C. loewi and L. richardsi were caught only in Ketkovice and Brno, respectively.L. sericata was the dominant species in densely populated places in both areas.L. caesar was the dominant species in forests and one forest park in Brno and in the forests around Ketkovice.Although L. bufonivora is considered to be a rare species, it was not rare and it was the most numerous in forests and recreation areas near water reservoir and river banks. Synanthropic flies, densely populated areas, Czech RepublicHuman-made environments such as agrobiocoenoses and densely populated areas of towns and villages provide suitable conditions for the development of larvae of synanthropic blowflies (Schoof et al. 1954;Povoln˘and Rozsypal 1968).The blowflies are able to transmit many causative agents of diseases (Nuorteva 1959;Greenberg 1973;Daniel et al. 1990).Some of the blowflies cause myiases (Mináfi et al. 1995;Zavadil et al. 1997).According to Gregor and Rozko‰n˘(1997), four species of the genus Calliphora Robineau-Desvoidy, 1830, nine species of the genus Lucilia Robineau-Desvoidy, 1830 and one species of the genus Protophormia Townsend, 1908 occur in Moravia (Table 1).The occurrence of blowflies in Brno was studied by Jacentkovsk˘ (1941) many years ago.However, within the last 60 years, Jacentkovsk˘'s study area has changed dramatically by increased traffic, industrialization, air pollution and growth of densely populated areas, especially large blocks of flats producing enormous amount of municipal garbage.The fly fauna of Brno and its surroundings has been studied by Gregor (1991) and Rozko‰n˘ and VaÀhara (1993) during last ten years, but the occurrence of blowflies living in the town centre remained unknown.Because of increasing popularity of pets, great attention of veterinarians is given not only to well-known blowfly species causing myiases of birds and mammals, but also to Lucilia bufonivora Moniez, 1876, which may attack free-living or house-kept amphibians (Zavadil et al. 1997).The aim of this study was to compare the occurrence of blowflies of the genera
