Native parasitoids attacking the invasive chestnut gallwasp Dryocosmus kuriphilus (Hymenoptera: Cynipidae) across its expanding range in Europe

considered to be the most important pest of chestnut (Castanea) worldwide. Originating from China, this pest was accidentally introduced to Japan in 1941, colonized Korea in 1958 and the USA in 1974. In 2002 it was detected for the first time in Europe (in Piedmont, Italy). Since 2002, DK has established itself and spread throughout Italy all the way to Sicily, and has also been reported in France in 2005, Slovenia in 2005, Hungary in 2009, Switzerland in 2009, Croatia in 2010, Slovakia and Czech Republic in 2011 and Spain in 2012. Within the native range in China, 11 species of parasitoids were found to be associated with DK which kept the host populations at low densities. In Japan, South Korea, the USA and Italy the attack rates of indigenous parasitoid species are low, typically less than 2%. We study the native parasitoid complexes of DK across it expanding range in north Italy (since 2005), Slovenia (since 2010) and Croatia (since 2011). Twenty-seven chalcidoid parasitoid species have so far recruited naturally to the new host in Italy during 2005-2010. In Slovenia 7 species were found in 2010, 11 in 2011 and 13 in 2012 ; in Croatia 11 in 2011 and 15 in 2012. Recruitment of parasitoids to DK depends on actual parasitoid species composition of oak gallwasps to be found in the same locality and is higher in mixed chestnut-oak forests than in pure Castanea stands.
