The main aim of the study was to become acquainted with the daily and seasonal dynamics of flights of ten economically important aphid species in Johnson’s suction trap in Winna Góra in 2018–2020. In the 2018 a total of 3.584 winged aphid specimens were caught, in 2019 – 5.049, and in 2020 – 9.411. Five aphid species were noticed as the most numerous: Rhopalosiphum padi, Sitobion avenae, Aphis fabae, Myzus persicae and Anoecia corni. Members of bird cherry-oat aphid (R. padi) dominated in all the years of observation. The number of caught aphids depended on the weather conditions in individual decades. Harvest data, in conjunction with the course of temperatures and rainfall in individual years, may constitute the basis for establishing short- and long-term forecasts of the emergence of economically important aphid species.
