Egg parasitoids of the exotic invasive brown marmorated stink bug,  Halyomorpha halys  (Stål), were investigated using lab-reared fresh (live) and frozen (killed) lab-reared sentinel egg masses deployed for 72h on foliage in three habitats—woods, orchard, and soybean field—in Maryland, USA, in summer 2014. Four native hymenopteran species,  Telenomus podisi  Ashmead (Scelionidae),  Trissolcus euschisti  (Ashmead) and  Tr .  brochymenae  Ashmead (Scelionidae), and  Anastatus reduvii  (Howard) (Eupelmidae), developed and emerged from  H .  halys  eggs. One exotic parasitoid,  Trissolcus japonicus  (Ashmead), emerged, providing the first known occurrence of this species in North America. Native parasitoids emerged from frozen eggs significantly more often than from fresh eggs (89.3% of egg masses and 98.1% of individual eggs), whereas the exotic  Tr .  japonicus  did not show a similar difference, strongly suggesting adaptation to  H .  halys  as a host by  Tr .  japonicus  but not by the native species. Parasitoids were habitat-specific: all three  Trissolcus  species were significantly more likely to occur in the woods habitat, whereas  Te .  podisi  was found exclusively in the soybean field. Further investigations are required to elucidate evolving host-parasitoid relationships, habitat specificity, and non-target effects of  Tr .  japonicus  over the expanded range of  H .  halys  in North America.
