Popis:	Summary The research was conducted at the Polish Akademii of Science Botanical Garden in Powsin on five cultivars of park roses (Fruhlingsduft, Nevada, Marguerite Hilling, Poppius, Harison’s Yellow) and one wild form (Rosa moyesii). The aim of this study was to evaluate the number of the most important pests such as spider mites (Tetranichidae), aphids (Aphidoidea) and rose leafhopper (Edwardsiana rosae L.) on rose leaves and to select the cultivar which is the most resistant to these pests. The observations were conducted in 2012–2013. Ten leaves were collected both from the upper and lower part of the shoot. In the laboratory conditions the pests were counted and symptoms of their feeding were observed. The largest number of pests, especially mites, was found on the cultivar Fruhlingsduft rose. There were clear preferences in relation to cultivars in case of European red mite (Panonychus ulmi Koch), which showed in greater number only on the cultivar Fruhlingsduft and in 2013 also Nevada, despite the possibility to move to other bushes. The least number of pests was generally observed on the cultivar Poppius.
