“…The differences between the two studies may be partially explained by the fact that parasitoids in Europe and North America were different species with likely different parasitism success. In addition, in the present study freshly laid, sentinel egg masses were exposed for a maximum of 3 days, whereas in the United States naturally laid egg masses were collected, which have been reported to reveal higher parasitism levels than sentinel egg masses (Jones, Jennings, Hooks, & Shrewsbury, ). On the other hand, Dieckhoff et al () found in a nine years study conducted in northern Delaware (US) that the difference in parasitism levels between sentinel and naturally laid eggs was less pronounced.…”

“…However, the impact of natural enemies could be underestimated because in response to the outbreak of H. halys population in 2015, the use of broad‐spectrum insecticides in this region has increased significantly (Maistrello et al, ), likely negatively affecting the natural enemy community and abundance in the fruit orchards. In the United States, predation on sentinel egg masses was similarly low, ranging from 4% to 11% (Cornelius et al, ; Jones et al, ; Ogburn et al, ). In these surveys, tettigonids and carabids were identified as the most efficient predators of H. halys eggs (Morrison et al, ).…”

The invasive Halyomorpha halys (Heteroptera: Pentatomidae) is a key pest of fruits in the Emilia‐Romagna region of Italy. For the development of a sustainable management programme, knowledge of its native natural enemy community and its efficacy is essential. A three‐year field survey was conducted exposing H. halys egg masses in different types of habitats to investigate the efficacy of native natural enemies in reducing the H. halys populations in the Emilia‐Romagna region, where the stinkbug was first detected in 2012. Over the first year of the study, sentinel eggs from laboratory cultures were stapled to the underside of leaves in various host trees, whereas in following years H. halys adults were directly caged on branches in sleeve cages to allow natural oviposition. Over the examined years, low rates of parasitism (1%–3%) and predation (2%–5%) were observed. Parasitism was caused exclusively by the generalist parasitoid Anastatus bifasciatus.

“…This highly polyphagous pest feeds on >100 species of plants in 45 families including fruits, vegetables, field crops, and ornamental plants in both native and invaded habitats (Haye et al, 2014;Hoebeke and Carter, 2003;Lee et al, 2013), and is considered a nuisance when aggregating en masse while overwintering inside man-made structures (Hoebeke and Carter, 2003;Inkley, 2012). Some native North American insects have been identified as predators or parasitoids of H. halys, but are generally inconsistent in suppressing H. halys populations (Herlihy et al, 2016;Jones et al, 2014;Ogburn et al, 2016). As part of a classical biological control program for H. halys, foreign exploration has been conducted in Asia since 2007 (K. Hoelmer, unpublished data) and four species of egg parasitoids in the genus Trissolcus (Hymenoptera: Scelionidae) have been identified as potential biological control agents.…”

Nystrom Santacruz et al.: Cold tolerance of T. japonicus and T. cultratus 1 Biological Control Cold tolerance of Trissolcus japonicus and T. cultratus, potential biological control agents of Halyomorpha halys, the brown marmorated stink bug Nystrom Santacruz et al.: Cold tolerance of T. japonicus and T. cultratus 2 ABSTRACT Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is native to Asia and has become a severe agricultural and nuisance pest in the U.S. Therefore, foreign exploration was conducted in Asia to identify potential classical biological control agents. Several Trissolcus spp. (Hymenoptera:Scelionidae) parasitize H. halys eggs in Asia and are being evaluated for potential release in the U.S. Since H. halys has invaded regions that experience sub-zero winter temperatures, cold tolerance is important for evaluation of Trissolcus spp. Our study compared the cold tolerance of populations of T. japonicus and T. cultratus, in order to assess relative suitability of the populations for release. We used thermocouple thermometry to determine the supercooling point and lower lethal temperature after brief exposure to cold temperature for each population. In addition, we subjected adult T. japonicus to a short photoperiod and low temperature regime, which increases cold tolerance in H. halys, to observe whether these conditions cause a change in cold tolerance in the parasitoid. We found that populations of both species froze and survived at colder temperatures than those reported for H. halys. In addition, there were no ecologically relevant differences in the temperature at which freezing or survival occurred among populations of either species, indicating that these populations are equally cold tolerant and suitable for introduction. Finally, T. japonicus does not acclimate by increasing cold tolerance in response to conditions that increase cold tolerance in H. halys, suggesting that the above-mentioned measures of cold tolerance are ecologically relevant.

“…However, Jones et al (2014) found that sentinel H. halys eggs (laboratory-laid) substantially underestimated parasitism rates of H. halys compared to wild eggs (field-laid) in outdoor ornamental nurseries. Wild eggs yielded higher parasitism, parasitoid abundance and species richness (Jones et al 2014). Therefore, biological control programs should be evaluated using wild egg masses for parasitoid activity and abundance in the field.…”

“…The natural enemy complex of H. halys has been studied to develop biological control programs (Abram et al 2014a,b;Gariepy et al 2014b;Gouli et al 2012;Jones et al 2014;Martinson et al 2013;Talamas et al 2013). In particular, multiple species of egg parasitoids in Trissolcus spp.…”
