Abstract

The scelionid parasitoid Trissolcus basalis (Wollaston,1858) has been detected in Belgium for the first time based on specimens reared from a parasitized egg mass of Nezara viridula (Linnaeus,1758) collected in an urban garden at Sint-Amandsberg, Ghent. Identification was based on adult morphology and DNA barcoding. This is presently believed to be the northernmost record in Europe of T. basalis and could be the consequence of a northward expansion of this species due to climate change. This first record may be of economic importance for the biological control of stink bug pests in Belgian vegetable and fruit production.
