First report of Dryocosmus kuriphilus in Turkey

The NPPO of Turkey recently informed the EPPO Secretariat of the first record of Dryocosmus kuriphilus (Hymenoptera: Cynipidae - EPPO A2 List) on its territory. The pest was first found in April 2014 on chestnut trees (Castanea sativa) in several forest areas in the province of Yalova (Marmara region). D. kuriphilus was identified on the basis of its morphological characteristics. These findings were made during an official survey initiated in March 2014. Results showed that the pest is still of limited distribution in Turkey, as it has only been found in the province of Yalova. The infested areas in Yalova province are defined as follows: villages of Sugören, Kirazlı, Elmalık, Kurtköy, Soğucak, Güneyköy (Merkez county), Sermayecik (Altınova county), Gacık, Çukur, Laledere, Dereköy, Burhaniye (Çİftlikköy county), Ortaburun (Çınarcık county). It is suspected the pest has been introduced through the movement of infested twigs and young plants. Phytosanitary measures elaborated on the basis of the EU Commission Decision 2006/464/EC were taken.
The pest status of Dryocosmus kuriphilus in Turkey is officially declared as: Present, only in some areas where host plants are grown. The infested areas in Yalova province are indicated above.
