TY - JOUR N2 - In 1993–1995 from the cabbage aphid colonies, fed on nine different varieties of Brassica oleracea L. syrphid larvae and pupae were collected. The remaining emerged adults of Syrphidae were classified to eight species. The parasitization varied within the years of observation and oscillated from 14,4% to 46,4%. Four parasitic Hymenoptera: Diplazon laetatorius (F.), Diplazon sp., Pachyneuron grande (Thoms.), and Syrphophagus aeruginosus (Dalm.) were reared. The parasitoids identified belong to the following three families Ichneumonidae, Pteromalidae, and Encyrtidae. The largest group of reared parasitoids belonged to the family Ichneumonidae of which the most frequent was Diplazon laetatorius (F.). It occurred in each year of observations. The parasitization by D. laetatorius reached 21,7%.
