The Oriental Chestnut Gall Wasp, Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae), originally from China, has become established in several other Asian countries, the USA, and Europe where it is parasitized by various species of Chalcidoidea that normally exploit oak gall wasps (Aebi et al. 2007). In the USA, D. kuriphilus was first recorded in 1974 and has been found in 10 states as far north as Pennsylvania and Ohio, on two Nearctic species of Castanea: C. dentata (Marshall) Borkhausen, and C. pumila Miller (Dixon et al. 1986; Anagnostakis 1997; Warmund 2009). Viggiani and Nugnes (2010) described and illustrated the larva. Numerous other Nearctic species are assigned to Dryocosmus (Burks 1979), the most recently described on Chrysolepis spp. (Buffington and Morita 2009).
