(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, 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 in Greece. From June to October 2020, we sampled naturally field-laid egg masses to recover native parasitoids. A total of 20 egg masses of 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 eggs- (Geoffrey) (Hymenoptera: Eupelmidae) and (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 in Greece, and the use of these native egg parasitoids in biological control programs may be a viable management strategy.
(斯塔尔)(半翅目:蝽科)是东亚的特有物种;2007年被引入欧洲。它的寄主范围很广,以170多种寄主植物为食,对作物生产有重大影响。在希腊,它给猕猴桃、桃子和四季豆的生产造成了重大损失;因此,控制该物种(包括生物防治)至关重要。在这里,我们关注希腊本地天敌对(斯塔尔)的潜在影响。2020年6月至10月,我们对自然产在田间的(斯塔尔)卵块进行采样,以获取本地寄生蜂。从希腊北部不同地点的受侵染田地中总共收集了20个(斯塔尔)卵块。在529枚卵中,有45只寄生蜂成功孵化。总体寄生率为8.5%。我们发现两种膜翅目卵寄生蜂攻击(斯塔尔)的卵——(杰弗里)(膜翅目:旋小蜂科)和(瓦西里耶夫)(膜翅目:跳小蜂科),前者占所有回收寄生蜂的58%。这些结果有助于了解希腊攻击(斯塔尔)的天敌群落,在生物防治计划中使用这些本地卵寄生蜂可能是一种可行的管理策略。
