MARKOVA, EMILIA and TEODORA TEOFILOVA, 2011. Syrphid communities (Syrphidae, Diptera) in basic types of agroecosystems in Karlovo valley (Bulgaria). Bulg. J. Agric. Sci., 17: 49-54
This contribution is the first ecologicaly-faunistic study of the syrphid flies from Karlovo valley. Syrphid cenoses in two basic types of agroecosystems were examined – cereals with merged surface and maize. Fourteen agroecosystems were explored. Main population and cenotic parameters of the syrphid communities were identified and analysed: species composition, evaluated qualitatively and quantitatively; occurrence of the species; population density; general average density; dominant and ecological structure. The study established 14 species syrphid flies. All species were new for the syrphid fauna of the valley.
