“…Trissolcus euschisti (Ashmead) and T. edessae Fouts (flavipes group) have been reared from H. halys eggs in North America, but at very low rates if the eggs are viable, indicating that they recognize H. halys as a potential host but are largely unable to complete development (Abram et al 2017). Outside of the flavipes group, T. basalis (Wollaston) and T. solocis Johnson (basalis group) have been reared from live, sentinel H. halys eggs (Balusu et al 2019a, Balusu et al 2019b, but these records are considered to be rare events.…”

“…In recent years, DNA barcode sequences have increasingly been used to confirm morphology-based identification of Trissolcus species (Ganjisaffar et al 2018, Balusu et al 2019b, Talamas et al 2015b, Abram et al 2019, Stahl et al 2018, Sabbatini Peverieri et al 2018. In some cases, this is primarily a supplement to morphological diagnosis, and in others it is an invaluable means of confirmation.…”

As the brown marmorated stink bug (Halyomorpha halys) has spread across the Northern Hemisphere, research on its egg parasitoids has increased accordingly. These studies have included species-level taxonomy, experimental assessments of host ranges in quarantine, and surveys to assess parasitism in the field. We here present a molecular phylogeny of Trissolcus that includes all species that have been reared from live H. halys eggs. Species-group concepts are discussed and revised in the light of the phylogenetic analyses. The analyses indicate that the ability to successfully parasitize H. halys eggs is not phylogenetically constrained, but the most effective parasitoids are all found in the flavipes species group.

“…In North America and Europe, few native parasitoids can successfully develop on H. halys eggs (Abram et al, 2017; Costi et al, 2019; Konopka et al, 2019; Balusu et al, 2019a,b; Stahl et al, 2019a; Moraglio et al, 2020). The generalist Anastatus bifasciatus (Geoffroy) has emerged from both field‐laid and sentinel H. halys egg masses in Italy and Switzerland (Haye et al, 2015; Roversi et al, 2016; Costi et al, 2019; Moraglio et al, 2020).…”

The invasion of Halyomorpha halys (St al) (Hemiptera: Pentatomidae) has caused severe economic damage in crops in North America and Europe, motivating research to identify its natural enemies, both in native and invaded areas. In its Asian native range, the main natural enemies are egg parasitoids, among which the most effective are Trissolcus japonicus (Ashmead) and Trissolcus mitsukurii (Ashmead) (Hymenoptera: Scelionidae) in China and Japan, respectively. In Europe, biology, host range, and impact of most native scelionid species are not well-known. The present study aimed to investigate (1) presence and abundance of scelionid species that parasitize native Pentatomidae and Scutelleridae eggs in Northwest Italy, and (2) their ability to develop on H. halys eggs. During 4-year field surveys, egg masses were collected and reared until bug nymph or adult parasitoid emergence. Then, the obtained scelionid females were tested for their ability to parasitize H. halys eggs in laboratory no-choice experiments. Egg masses of all collected bug species were parasitized, and Telenomus spp. (Hymenoptera: Scelionidae), Trissolcus belenus (Walker), and Anastatus bifasciatus (Geoffroy) (Hymenoptera: Eupelmidae) were the most common parasitoids. In the laboratory, Trissolcus kozlovi Rjachovskij was the only species to significantly produce offspring from fresh H. halys eggs, whereas all tested Trissolcus species significantly induced host egg abortion (non-reproductive effects). This study provides knowledge of the parasitoid species associated with native bugs, and represents a starting point to investigate the intricate interactions between native and exotic parasitoids recently found in northern Italy. These egg parasitoids could potentially be effective biocontrol agents of H. halys.

“…Many egg parasitoids were found in the invaded range, but overall parasitism levels remained low (<1 to 15.1%) [ 61 , 62 ] and variable (e.g., 0 to 59%, based on parasitoid emergence across surveys) [ 49 ]. As in the native range, most egg parasitoids were from the genera Trissolcus , Telenomus, and Anastatus [ 49 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 ], but some studies also recovered Ooencyrtus spp. [ 77 , 78 ], with at least one species not considered a hyperparasitoid [ 34 ].…”

The brown marmorated stink bug Halyomorphahalys (Stål) (Hemiptera: Pentatomidae) is native to Northeast Asia, but has become a serious invasive species in North America and Europe, causing major damage to crops. While it has not established itself in Australia, it has been intercepted at the border several times, indicating that future incursions and establishment are a case of when, not if. Biological control is one of the few control options for this species and will be important for managing H.halys should it become established in Australia. Prioritizing species that could be used as biological control agents would ensure Australia is prepared. This study summarizes the literature on natural enemies of H. halys in its native and invaded ranges and prioritizes potential biological control agents of H.halys that could be used in Australia. Two egg parasitoid species were identified: Trissolcusjaponicus (Ashmead) and Trissolcusmitsukurii (Ashmead) (Hymenoptera: Scelionidae). Future efforts to develop biological control should focus on T. mitsukurii, as it is already present in Australia. However, little is known about this species and further work is required to: (1) assess its potential effectiveness in parasitizing H. halys, (2) determine its current distribution and (3) host range in Australia.
