Abstract
The North American oak lace bug (Corythucha arcuata) was first discovered in Europe in Northern Italy (2000). In 2013, it was found in Hungary. In the last five years, particularly in 2016 and 2017, the species showed rapid area expansion. Until autumn 2017 it has been found in all Hungarian counties except five ones (Borsod-Abaúj-Zemplén, Nógrád; Győr-Moson-Sopron, Vas and Veszprém). Outbreaks were recorded in several pedunculate oak stands in Békés, Csongrád, Jász-Nagykun-Szolnok and Baranya counties, covering ca. 5,000 hectares of forest area in total. Further spread and outbreaks are expected in the next years. The severe infestation causes mass yellowing of the foliage by early and mid-July, long term consequences of this effect are not yet known. Neither efficient nor environmentally friendly control methods were established by now.
