Classical biological control has been identified as the most promising approach to limit the impact of the invasive pest species Halyomorpha halys (Heteroptera: Pentatomidae). This study investigated the parasitism rate at sites where the biocontrol agent Trissolcus japonicus (Hymenoptera: Scelionidae) was released and where its unintentional introduction took place, in the Trentino–South Tyrol region. The effect of land-use composition was studied to understand which factors favor the establishment of hosts and parasitoids, including native and exotic species.

影响短期寄生蜂建立的因素和武士黄蜂 Trissolcus japonicus 对 Halyomorpha halys 的生物控制效果

经典生物控制已被确定为限制入侵害虫物种Halyomorpha halys （异翅目：Pentatomidae）影响的最有希望的方法。本研究调查了特伦蒂诺 - 南蒂罗尔地区生物防治剂Trissolcus japonicus（膜翅目：Scelionidae）释放和无意引入地点的寄生率。研究了土地利用构成的影响，以了解哪些因素有利于寄主和拟寄生物（包括本地和外来物种）的建立。
