(Stål) (Hemiptera: Pentatomidae) is an invasive pest causing significant damage to tree crops. Our study examined the impact of newly designed aggregation pheromone-baited 'mini-sailboat' (MSB) traps for controlling and its effect on the spatial distribution of fruit damage. Four replicates of four traps, with a total of 16 MSB traps, were placed along a 1.3 km border of apple orchards, concentrating the traps on one side of the orchards. A fruit damage assessment for incidence and severity was conducted at increasing distances from the orchard border where the traps were placed, encompassing 107 assessment points. Our study showed that deploying MSB traps along the orchard border significantly increased fruit damage within the first 45 m compared to control plots without traps. However, beyond the first 45 m from the border, there was a significant reduction in damage incidence. In the treated plots, 50% of the damage occurred within 26 m of the traps, while in control plots, within 85 m. Shifting the fruit damage pattern means restricting the pests lingering in a narrow strip near the MSB traps, which paves the way for improved techniques to restructure the crop perimeter.
斯塔尔蝽（半翅目：蝽科）是一种入侵性害虫，对果树造成严重损害。我们的研究考察了新设计的聚集信息素诱捕“迷你帆船”（MSB）诱捕器对害虫的控制效果及其对果实损伤空间分布的影响。沿着苹果园1.3公里的边界设置了四个诱捕器的四个重复组，共16个MSB诱捕器，诱捕器集中放置在果园的一侧。在离放置诱捕器的果园边界越来越远的地方进行了果实损伤发生率和严重程度的评估，涵盖107个评估点。我们的研究表明，与没有诱捕器的对照地块相比，沿着果园边界部署MSB诱捕器在最初45米内显著增加了果实损伤。然而，在离边界超过45米的地方，损伤发生率显著降低。在处理过的地块中，50%的损伤发生在离诱捕器26米以内，而在对照地块中，发生在85米以内。改变果实损伤模式意味着限制害虫在MSB诱捕器附近的狭长地带徘徊，这为改进作物周边结构的技术铺平了道路。
