Eradication of Dryocosmus kuriphilus from the Netherlands

In the Netherlands, the presence of Dryocosmus kuriphilus (Hymenoptera: Cynipidae – EPPO A2 List) was first noticed in July 2010 on 5 sweet chestnut trees (Castanea sativa), in a wholesale company located in Boskoop (see EPPO RS 2010/134). These infested trees were found during a regular plant passport field inspection in one lot (5 trees, 4-5 m high) which had been delivered in 2008 from an Italian nursery. All infested trees were destroyed. Three successive specific surveys were conducted in 2010, 2011 and 2012 and did not detect the pest. Therefore, the NPPO of the Netherlands considers that D. kuriphilus has successfully been eradicated. Nevertheless, specific surveys on D. kuriphilus will continue in the Netherlands.
The pest status of Dryocosmus kuriphilus in the Netherlands is officially declared as: Absent, eradicated.
