notes
Species originating from Japan, Korea and Asiatic Russia, that probably was introduced in eastern Europe around 1970, and now is omnipresent in Czechia and Slovakia (Sefrová, 2002a). The species is expanding fast in Hungary and Germany, and has also been found in the Baltic States (Csóka, 2003a; Noreika, 1998a; Reinhardt & Rennwald, 2007a). First record in the Benelux was in 2009.
The infestation has a significant, negative, effect on, among other things, wood production and sugar content of the nectar (Ermolaev & Zorin, 2011a).
Preference for shadow leaves of the lower branches close to the stem (Ermolaev & Zorin, 2011b).
