Halyomorpha halys (Stål) (Hemiptera: Pentatomidae) is an invasive pest which feeds on numerous economically significant crops. Many integrated pest management strategies for this species rely on effective season-long monitoring for H. halys populations, including attract-and-kill and threshold-based insecticide sprays. Previous studies have shown that a black pyramid trap effectively captures all mobile life stages of H. halys, however, these bulky, ground-deployed traps can be impractical in active orchard rows. Clear sticky cards have been used as a more practical tool for monitoring when paired with the H. halys aggregation pheromone and synergist. Here, the efficacy of deploying single- or double-sided sticky cards hanging in trees or deployed on wooden stakes was compared to standard black pyramid traps over 2 years. The efficacy of single-sided sticky cards deployed on wooden stakes was also evaluated after occlusion of 25%, 50%, or 75% of the surface area by 2D inert materials and 3D organic matter. Single-sided sticky cards were also exposed to simulated sunlight and rainfall for 0, 4, 8, and 12 wk before deployment on wooden stakes. Captures of H. halys adults using sticky cards deployed on wooden stakes were comparable to pyramid traps. Occlusion of cards by 25% or more of any material type led to a decrease in H. halys captures, however, weathering did not influence capture. These data show that clear sticky cards deployed on wooden stakes are effective for season-long monitoring of H. halys in apple orchards, and card replacement should be driven by maintenance of cleanliness.
红蝽（Stål）（半翅目：Pentatomidae）是一种入侵性害虫，以许多具有重要经济意义的作物为食。针对该物种的许多综合虫害管理策略依赖于对 H. halys 种群进行有效的全季监测，包括吸引和杀灭以及基于阈值的杀虫剂喷雾。先前的研究表明，黑色金字塔陷阱有效地捕获了 H. halys 的所有移动生活阶段，但这些体积庞大、地面部署的陷阱在活跃的果园行中可能不切实际。当与 H. halys 聚集信息素和增效剂结合使用时，透明粘性卡片已被用作监测的更实用工具。在这里，将单面带或双面带粘性卡片挂在树上或部署在木桩上的效果与标准黑色金字塔陷阱进行了比较，为期 2 年。还评估了在 2D 惰性材料和 3D 有机物遮挡 25%、50%或 75%表面积后，部署在木桩上的单面带粘性卡片的效果。单面带粘性卡片还暴露在模拟阳光下和雨水中 0、4、8 和 12 周，然后再部署在木桩上。使用木桩上部署的粘性卡片捕获的 H. halys 成虫与金字塔陷阱相当。任何材料类型的遮挡率达到 25%或更高都会导致 H. halys 捕获量减少，但是风化不会影响捕获。这些数据表明，部署在木桩上的透明粘性卡片可有效监测苹果园中的 H. halys 全季，并且应根据清洁度的维护来更换卡片。
