“…In laboratory studies, it parasitized some, but not all pentatomid species tested [ 16 , 23 , 91 , 92 ]. In Japan, three non-target species are attacked, two of which are in the genus Plautia Stål [ 39 , 93 ]. A careful assessment of the potential risks to Australian Pentatomidae native fauna would need to be completed before T. japonicus could be considered as a possible biological control agent for H. halys there.…”

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.

“…However, this does not explain why the parasitoid responds to cues associated with the novel host. A hypothetical explanation for this could be that N. viridula induces in soybean a defensive response that might be similar to that induced by other herbivores, like Nezara antennata Scott, native to Eastern Asia (Panizzi et al 2000) and listed as host of T. mitsukurii (Ryu and Hirashima 1984). It is known that N. viridula and N. antennata share common volatile compounds (Borges and Blassioli-Moraes 2017), however, whether they also induce similar plant responses is unknown.…”

“…Dolycoris baccarum has a wide distribution in the Paleartic region (Panizzi et al 2000), occurring also in Asia where it is a pest of several crops including soybean (Kobayashi 1981;Nakamura and Numata 2006). Although D. baccarum is listed in the host range of T. mitsukurii (Ryu and Hirashima 1984), there are no quantitative data related to the prevalence rate of this parasitoid. On the other hand, naturally-laid and sentinel egg masses of D. baccarum are highly parasitized in Chinese orchards by other parasitoids, i.e., T. japonicus (Zhang et al 2017).…”

“…Additionally, feral populations of another Asian egg parasitoid species, Trissolcus mitsukurii (Ashmead) (Hymenoptera: Scelionidae), have been recently detected in northern Italy on H. halys egg masses (Sabbatini-Sabbatini-Peverieri et al 2018;Moraglio et al 2020;Scaccini et al 2020). Frequently described as an indigenous parasitoid of Nezara viridula L. (Hemiptera: Pentatomidae) in Japan Kiritani 1963, Arakawa et al 2004), T. mitsukurii parasitizes also H. halys and other stink bug species in China and Japan (Ryu and Hirashima 1984;Arakawa and Namura 2002;Chen et al 2020). In Italy, adventive populations of T. mitsukurii have shown high parasitism e cacy on H. halys, comparable to that of T. japonicus (Scaccini et al 2020).…”

Field release of classical biocontrol agents requires prior risk assessment to ensure that non-target effects are averted. No-choice and choice bioassays can provide basic information on the physiological host range of the candidate agent. However, other experimental methods, like olfactometer bioassays of host-plant complexes, can depict more realistically the likelihood that the released biocontrol agent localizes non-targets in the field. Halyomorpha halys Stål (Hemiptera: Pentatomidae) is native to Asia and invasive in North America and Europe, where it represents a major threat for crops. The Asiatic egg parasitoid Trissolcus mitsukurii (Ashmead) is adventive in Italy and exhibits high parasitization ability on H. halys. In the light of evaluating T. mitsukurii for H. halys biocontrol, its physiological host range has been already partially explored. Here, we investigated the ability of the parasitoid to exploit odours associated with H. halys or with the following non-targets: Arma custos F., Dolycoris baccarum L., Eurydema ventralis Kolenati, and Nezara viridula L. (all Hemiptera: Pentatomidae). Specifically, using a Y-tube olfactometer, we tested the response of parasitoid females to plants bearing naturally laid eggs, to physogastric females or eggs of the different species. We observed that T. mitsukurii is only attracted by plants challenged by eggs of H. halys or N. viridula, while it is not attracted by physogastric females or eggs alone. Remarkably, T. mitsukurii was almost repelled by plants bearing eggs of the beneficial A. custos. Our results usefully contribute to a more valuable assessment of the potential non-target risks in case of parasitoid release.

In crop systems, successful management of invasive insect herbivores can be achieved through the introduction of exotic biocontrol agents, i.e. parasitoids or predators, having a coevolutionary history with the pest. To avert threats to local biodiversity, recent legislations require a risk assessment for the organism to be released. Evaluation of its ability to exploit, for host location, odours associated with target and non-target species is crucial for a better definition of its ecological host range. Using Y-tube olfactometer in quarantine laboratory, we investigated the ability of the Asiatic egg parasitoid Trissolcus mitsukurii (Hymenoptera: Scelionidae) to exploit odours associated with the global invader Halyomorpha halys (Hemiptera: Pentatomidae) and with non-target stink bugs native to Southern Europe. We demonstrated that T. mitsukurii is attracted by plants exposed to feeding and egg deposition of the coevolved H. halys or the native Nezara viridula, while it is not attracted by physogastric females or eggs alone. Remarkably, T. mitsukurii is repelled by plants bearing eggs of the beneficial stink bug, Arma custos. Our results usefully contribute to a more thorough and nuanced assessment of the potential non-target risks in case of massive parasitoid release.
