The purpose of the present studies was to determine the frequency of particular species from the aphid community colonizing roses of different utility groups (Rosa rugosa Thunb., Rosa multiflora Thunb., park rose cv. ‘Grandhotel’, cluster flowered roses) growing in the urban conditions of Lublin. The studies were conducted in the years 2001–2003. The highest constancy of occurrence was characteristic of M. rosae. This species was observed annually on all roses in each site. The lowest frequency was characteristic of L. trirhodus, E. tiliae, M. euphorbiae, Aulacorthum sp. and those aphids belonged to accidents. Establishing the total frequency of the studied aphid species gives a picture of the occurrence of these species in a definite area. However, only the analysis of the structure of occurrence constancy of these species on definite host plants in particular sites makes it possible to grasp their interrelations.
