In 2006–2009, the occurrence of leaf rollers was monitored in three different regions of Poland. The results of observations suggested diversified number of rollers in different regions and over different years. The highest number of recorded Archips rosanus rollers was in 2008, whereas Pandemis heparana roller peak occurred in 2007. Since 2007, in the region of Central Poland, the number of Adoxophyes orana and Spilonota ocellana roller systematically increased. A. orana roller occurred in high intensity throughout all the orchards in which conducted the research. Considerable differences were stated in dates of moths’ flight initiation within individual orchards and vegetative seasons. The dynamics of moths’ flight was also differentiated. Because of this there is a need of scheduling different treatment dates for each region and orchard.
