Dryocosmus kuriphilus found again in the Czech Republic

In the Czech Republic, Dryocosmus kuriphilus (Hymenoptera: Cynipidae – EPPO A2 List) had first been found for the first time in 2012 on 2 chestnut trees (Castanea sativa) in a private garden and then in 3 potted plants in a garden centre (EPPO RS 2012/141). Infested plants were destroyed, and the results of a subsequent intensive survey were all negative. However, in May 2020, the presence of D. kuriphilus was officially confirmed in samples taken from a C. sativa tree in a private garden in Prague. Another confirmed finding was made on a Castanea plant which had been bought in a shop in Jihlava (Vysočina region). As the pest is no longer regulated in the EU (except for certain protected zones), no official measures have been taken.

The pest status of Dryocosmus kuriphilus in the Czech Republic is officially declared as: Present, restricted distribution.
