Resumen

This report concerns the second official finding of Dryocosmus kuriphilus in the Netherlands, whereby the morphological identity was confirmed on 19 June 2015. Typical galls were detected on nine trees of Castanea sativa at five locations in the border area with Germany. Trees were probably affected at least since 2013 since several galls were lignified. The origin of the finding is unknown. Natural spread from the Bottrop area in Germany could have taken place. The organism is listed as a harmful organism in EU directive 2000/29/EC for protected zones and is listed on the EPPO A2 list. It concerns the second finding of this pest in the Netherlands. The first record in July 2010 in another part of the Netherlands (municipality Boskoop) concerned five trees of Castanea sativa originating in Italy whereby 137 galls were detected and two living female adults. After three years of specific surveillance without further findings, this first outbreak was considered eradicated in October 2013 (see update pest report October 2013). No measures are taken in view of the repeal of EU emergency measures for Dryocosmus kuriphilus in 2014 (Commission decision 2006/464/EC).
