Damages by the Green leafhopper (Cicadella viridis L.) to young Alnus glutinosa, Acer pseudoplatanus and Fraxinus excelsior are reported from Carinthia (Austria) in 2002 and 2003. Necroses on the stems resulting from egg layers of the leafhoppers were leading to severe crown dieback. Predispositions for epidemic occurrence as well as preventive measures are discussed.
