First report of Corythucha arcuata in Germany
The NPPO of Germany recently informed the EPPO Secretariat of the first record of the oak lace bug, Corythucha arcuata (Hemiptera: Tingidae – formerly EPPO Alert List) on its territory. In Baden-Wüttemberg, a member of the public found C. arcuata on oak trees in a forest next to a railway line. The Plant Protection Service then carried out a survey. The outbreak was found to cover an area of at least several km wide. As the pest is already present in many neighbouring countries south of Germany, it is presumed that C. arcuata has spread from there and is expected to spread further. In addition, there are no appropriate phytosanitary measures available to eradicate or contain the outbreak. A preliminary pest risk assessment was carried out and the pest was not classified as a potential quarantine pest.
The pest status of Corythucha arcuata in Germany is officially declared as: Present, restricted distribution.
