During the sampling period, 243 syrphid larvae belonging to seven species were collected from M. cerasi colonies on P. avium. Episyrphus balteatus Deg. and Epistrophe eligans (Harr.) were the most numerous species amongst the materials gathered, followed by Syrphus ribesii (L.) and S. vitripennis Meig. All of these species play an essential role in reducing M. cerasi populations. Amongst the Coccinellidae occurring in black cherry aphid colonies, Adalia bipunctata L. was the dominant species, while the subdominant was Coccinella septempunctata L. and Propylaea quatuordecimpunctata (L.).
