In recent years, several allochthonous species from the order Hemiptera have been detected in Slovakia. Most of them are pests of ornamental plants, reducing their ornamental value. In May 2024, adults of Cacopsylla pulchella (Löw, 1877) were recorded at the Arboretum Mlyňany, and the following year this pest was found in 3 additional localities (Nové Zámky, Nitra, Cabaj-Čápor). In addition to adults, eggs and nymphs were also found on Cercis siliquastrum, C. canadensis and C. chinensis. In 2025, a growing population of this insect pest was found, which can cause significant damage to Cercis specimens. Further monitoring is required to collect data on this pest’s life cycle to ensure optimal control measures in Slovakia.
