Abstract Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) has been managed primarily with broad-spectrum insecticides in orchard systems. Recently, IPM techniques have been developed specifically for managing H. halys in apple orchards to reduce insecticide inputs and take advantage of its perimeter-driven behavior. In 2015 and 2016, we compared these IPM tactics to one another and an untreated control to measure differences in overall crop protection and insecticide inputs. Tactics included trap-based threshold-triggered spray applications, perimeter-based attract-and-kill (AK) trees treated every 7- and 14-d, and perimeter spray applications applied every 7- and 14-d. All plots were monitored with baited black pyramid traps deployed in plot interiors. In both years, mean number of H. halys captured in untreated control plot traps was significantly greater than plots managed using IPM tactics. In 2015, significantly more insecticide applications were made in 7- and 14-d perimeter and AK plots compared with trap-based threshold plots. There was no significant difference in the percentage of injured fruit in plot interiors among IPM tactics; all were significantly lower than the control. In 2016, significantly more insecticide applications were made in 7-d perimeter spray and AK plots compared with all other treatments. Significantly less injury was detected in plot interiors for 7- and 14-d perimeter and trap-based threshold plots compared with the control and 7- and 14-d AK plots. Although all IPM tactics reduced H. halys injury in apples using a trap-based treatment threshold required fewer insecticide inputs and only during brief periods of the season, while all others required season-long maintenance.

苹果园Halyomorpha halys (Hemiptera: Pentatomidae) 综合病虫害管理策略的比较和改进

摘要 Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) 在果园系统中主要使用广谱杀虫剂进行管理。最近，IPM 技术专门用于管理苹果园中的 H. halys，以减少杀虫剂投入并利用其周边驱动行为。2015 年和 2016 年，我们将这些 IPM 策略与彼此和未经处理的对照进行了比较，以衡量整体作物保护和杀虫剂投入的差异。策略包括基于陷阱的阈值触发喷洒应用、每 7 天和 14 天处理一次的基于周边的吸引和杀死 (AK) 树木，以及每 7 天和 14 天喷洒一次周边喷洒应用。所有地块都使用部署在地块内部的诱饵黑色金字塔陷阱进行监控。在这两年中，平均 H. 在未经处理的控制小区陷阱中捕获的 halys 明显大于使用 IPM 策略管理的小区。2015 年，与基于陷阱的阈值地块相比，在 7 天和 14 天周长和 AK 地块中施用的杀虫剂明显更多。IPM策略中小区内部伤果率无显着差异；均显着低于对照。2016 年，与所有其他处理相比，在 7 天周边喷雾和 AK 地块中施用的杀虫剂明显更多。与对照和 7 天和 14 天 AK 地块相比，7 天和 14 天周界和基于陷阱的阈值地块在地块内部检测到的损伤显着减少。尽管所有 IPM 策略都降低了 H.
