| Sumario: | <i>Halyomorpha halys</i> (Stål) (Hemiptera: Pentatomidae) is an endemic species of East Asia; it was introduced into Europe in 2007. It has a wide range of hosts as it feeds on over 170 host plant species and significantly impacts crop production. In Greece, <i>H. halys</i> causes significant losses in the production of kiwi, peaches, and green beans; thus, control of this species (including biological control) is essential. Here, we focus on the potential impact of native natural enemies of <i>H. halys</i> in Greece. From June to October 2020, we sampled naturally field-laid <i>H. halys</i> egg masses to recover native parasitoids. A total of 20 egg masses of <i>H. halys</i> were collected from infested fields from different locations in northern Greece. Out of 529 eggs, 45 parasitoids managed to hatch successfully. The overall parasitism rate was 8.5%. We found two species of Hymenopteran egg parasitoids attacking <i>H. halys</i> eggs—<i>Anastatus bifasciatus</i> (Geoffrey) (Hymenoptera: Eupelmidae) and <i>Ooencyrtus telenomicida</i> (Vassiliev) (Hymenoptera: Encyrtidae), with the former comprising 58% of all parasitoids that were recovered. These results contribute to the knowledge about the natural enemy community that attacks <i>H. halys</i> in Greece, and the use of these native egg parasitoids in biological control programs may be a viable <i>H. halys</i> management strategy. |
