[Seasonal dynamics of synbovine flies (Diptera: Muscidae) during the grazing period in Jarov].

Synbovine flies and the seasonal pattern of their occurrence were studied throughout the grazing period in the cattle pastures of the Strakonice district. Skufin's traps were used for catching the flies. The total number of dipterous insects caught during the series of trappings in two- to three-week intervals was 2096. The family Muscidae (23 species) was represented most amply in the sample catches (Musca autumnalis 65.9%, Hydrotaea Meteorica 20.4%, Hydrotaea irritans 4.2%, Haematobosca stimulans 2.6%). The maximum occurrence of haematophagous species was recorded at the beginning and at the end of the grazing season. The maximum occurrence of secretophagous species was recorded in June.
