Abstract: The study was conducted in 2010 – 2011, in groves of Rosa sp. in region of Kazanlak. Account is taken of population dynamics, density and species composition of aphidophags of the Coccinellidae family. Methods used are surveys of the route, marked bushes and shaking with entomological bag and reporting the effectiveness of aphidophags to regulate populations of aphids in the planting of Rosa sp. used qualitative and quantitative methods. The largest share and important are species Coccinella septempunctata L., Adalia bipunctata L. and Adonia variegata Goeze, which have pivotal role in biological control of aphids.
