Abstract
The seasonal prevalence of flies was studied at a farmhouse located in the suburbs of the City of Daegu in Korea from April 1 through December 31,1964. Glass traps and sticky ribbons were used for collecting flies. The total number of flies collected was 100,961 of 24 species (41,287 males and 59,674 females). Predominant among the species collected were Musca domestica (39.5%), Phaenicia sericata+P. cuprina (17.7) and Boettcherisca peregrina (14.5). These three made up 72% of the total catch. Seasonal prevalences of flies show that the highest peaks of the fly abundance were observed to be in June or July at all sites for traps and other peaks in April, September or October. Three peaks were observed at the sites for ribbons. It was noted that the differences in species, collecting methods and their sites resulted in different patterns of seasonal prevalences. Breeding places and media of flies in Korea were discussed in view of the mode of life and the climate of the country. Known media of the 33 species were described.
