Dryocosmus kuriphilus found in Hesse, Germany

The NPPO of Germany recently informed the EPPO Secretariat of the occurrence of Dryocosmus kuriphilus (Hymenoptera: Cynipidae – EPPO A2 List) in Hesse. It can be recalled that the pest was first recorded in 2012 (see EPPO RS 2013/141) in several German länder. In September 2013, D. kuriphilus was found on sweet chestnut trees (Castanea sativa) at 2 locations, Zwingenberg and Hirschhorn (Neckar) in the state of Hesse. In Zwingenberg, one single tree was found to be infested. In Hirschhorn, 2 trees and their natural regeneration were infested. They belonged to a small group of approximately 25 trees in a forest. Galls were found on the leaves of the trees. The pest was identified morphologically. Official control measures were taken. The single infested tree in Zwingenberg has been destroyed. A survey in the surroundings of the infested trees has been initiated to delimit the infested areas, and it will continue in 2014. Demarcated zones in accordance with the EU Decision 2006/464/EC have been defined.
The pest status of Dryocosmus kuriphilus in Germany is officially declared as: Present, only in some areas (Baden-Württemberg, Nordrhein-Westfalen, Hesse), under official control.
