Since the establishment of the brown marmorated stink bug, Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) in North America and Europe, there has been a large, multi-group effort to characterize the composition and impact of the indigenous community of arthropod natural enemies attacking this invasive pest. In this review, we combine 98 indigenous natural enemy datasets spanning a variety of sampling methods, habitats, and geographic areas. To date, the vast majority of H. halys biological control research has focused on the egg stage, using sentinel egg masses to characterize indigenous parasitoid and predator communities and their contribution to H. halys egg mortality. Although egg parasitism and predation levels by indigenous natural enemies are low (typically <10% each) in most surveys, total egg mortality attributable to natural enemies can be higher (typically between 5 and 25%; up to 83%)—even though these values were likely underestimated in most cases because some mortality due to biological control was not recognized. In North America, where the most data are available, it appears that the relative prevalence of different indigenous parasitoid species varies among habitat types, particularly between crop and non-crop habitats. Predator species responsible for egg mortality are much less commonly identified, but appear to include a wide variety of generalist chewing and sucking predators. To date, studies of natural enemies attacking H. halys nymphs and adults are relatively rare. Based on our review, we identify a number of key research gaps and suggest several directions for future research.

Trissolcus japonicus (Ashmead) and T. cultratus (Mayr), comb. rev. are under study as classical biological agents to control the brown marmorated stink bug Halyomorpha halys (Stål) in North America. Here we present diagnoses for all Nearctic species of Trissolcus, including T. japonicus and T. cultratus comb. rev., and identification keys to enable separation of these species from the existing fauna. Trissolcus cultratus comb. rev. is removed from synonymy with T. flavipes. Two new species are described, Trissolcus valkyria sp. n. and T. zakotos sp. n. A neotype is designated for T. brochymenae and a lectotype is designated for T. basalis.

Abstract The generic concept of Calliscelio Ashmead is expanded to include variation in the shape of the metascutellum, the development of propodeal carinae, the presence of an epomial carina, the presence of malar striae, and the position of the toruli on the frons. This expansion follows circumscription of the genus based on the prioniform sensillum on the mandible, a character that is unique within Platygastroidea. We consider the prioniform state of the sensillum to be a synapomorphy for the genus, and treat Crama Galloway, Lispoteleia Galloway, Xentor Masner and Johnson, and Yunkara Galloway as junior synonyms of Calliscelio; the species of these genera are transferred herein. Calliscelio yunkara Talamas is provided as a replacement name for Yunkara inornata Galloway. A lectotype is designated for Calliscelio albicoxa (Dodd).

The establishment of invasive Halyomorpha halys (Stål) outside of its native range may impact native species assemblages, including other pentatomids and their scelionid parasitoids. This has generated interest in defining species diversity and host‐parasitoid associations in this system to better understand the impact of invasive alien species on trophic interactions in invaded regions. Information on scelionid–pentatomid associations in natural habitats is lacking, and species‐level identification of these associations can be tenuous using rearing and dissection techniques. Naturally occurring pentatomid eggs were collected in areas where H. halys has established in Canada and were analysed using a modified DNA barcoding approach to define species‐level trophic interactions. Identification was possible for >90% of egg masses. Eleven pentatomid and five scelionid species were identified, and trophic links were established. Approximately 70% of egg masses were parasitized; parasitism and parasitoid species composition were described for each species. Telenomus podisi Ashmead was the dominant parasitoid and was detected in all host species. Trissolcus euschisti Ashmead was detected in several host species, but was significantly more prevalent in Chinavia hilaris (Say) and Brochymena quadripustulata (Fabricius). Trissolcus brochymenae Ashmead and Tr. thyantae Ashmead were recorded sporadically. Parasitism of H. halys was 55%, and this species was significantly less likely to be parasitized than native pentatomids. The scelionid species composition of H. halys consisted of Te. podisi, Tr. euschisti and Tr. thyantae. Although these species cannot develop in fresh H. halys eggs, we demonstrate that parasitoids attempt to exploit this host under field conditions.
