Ooencyrtus mirus (Hymenoptera, Encyrtidae), discovered in Europe parasitizing eggs of Halyomorpha halys (Hemiptera, Pentatomidae)

Abstract

Ooencyrtus mirus Triapitsyn & Power (Hymenoptera, Encyrtidae) is recorded for the first time in Europe. It was found parasitising eggs of the invasive true bug Halyomorpha halys Stål (Hemiptera, Pentatomidae). This parasitoid is part of the Ooencyrtus telenomicida species complex where accurate species identification requires molecular data. Using morphology, the identification of the Ooencyrtus species parasitising brown marmorated stink bug eggs in Greece is ambiguous, but the sequences of the standard DNA barcode region (COI) and ITS2 place them in O. mirus.
