The spotted lanternfly, Lycorma delicatula White, is an invasive planthopper (Hemiptera: Fulgoridae) that was first detected in the United States in Berks County, PA, in 2014, and has since spread in the mid-Atlantic region. This phloem-feeding pest has a broad host range, including economically important crops such as grape where their feeding causes dieback of infested plants. Monitoring the presence and abundance of L. delicatula is of utmost importance to develop pest management approaches. Current monitoring practices include sticky bands deployed on tree trunks, sometimes paired with commercially available methyl salicylate lures. A drawback associated with sticky bands is the high numbers of nontarget captures. Here, we developed traps for L. delicatula based on a circle trap originally designed for weevils. These traps are comprised of a screen funnel that wraps around the trunk of a tree and guides individuals walking up the trunk into a collection device. In 2018 and 2019, we compared circle trap designs with sticky bands in Pennsylvania and Virginia. In both years, circle trap designs yielded captures that were equivalent to or exceeded captures of L. delicatula on sticky bands. Nontarget captures were significantly lower for circle traps compared with sticky bands. Presence of a methyl salicylate lure in association with traps deployed on host trees or vertical tree-mimicking posts did not increase L. delicatula captures compared with unbaited traps. Circle traps, modified using vinyl screen and a larger collection device, present an alternative to the current approach with reduced nontarget capture for monitoring L. delicatula.

为入侵的斑点灯笼蝇（半翅目：Fulgoridae）开发基于行为的监测和生物监测工具

斑点灯笼蝇 Lycorma delicatula White 是一种入侵性飞虱（半翅目：Fulgoridae），于 2014 年在美国宾夕法尼亚州伯克斯县首次发现，此后在大西洋中部地区蔓延。这种以韧皮部为食的害虫具有广泛的寄主范围，包括经济上重要的作物，如葡萄，它们的进食会导致受侵染植物枯死。监测 L. delicatula 的存在和丰度对于制定害虫管理方法至关重要。目前的监测做法包括在树干上部署粘性带，有时与市售的水杨酸甲酯诱饵配对。与粘性带相关的一个缺点是大量的非目标捕获。在这里，我们基于最初为象鼻虫设计的圆形陷阱开发了用于 L. delicatula 的陷阱。这些陷阱由一个环绕树干的筛网漏斗组成，并引导人们沿着树干走入收集装置。在 2018 年和 2019 年，我们比较了宾夕法尼亚州和弗吉尼亚州的圆形陷阱设计与粘性带。在这两年中，圆形陷阱设计产生的捕获量等于或超过粘性带上的 L. delicatula 捕获量。与粘性带相比，圆形陷阱的非目标捕获率显着降低。与无诱饵的陷阱相比，与部署在寄主树或垂直树模拟柱上的陷阱相关的水杨酸甲酯诱饵的存在不会增加 L. delicatula 的捕获量。圆形陷阱，使用乙烯基屏幕和更大的收集设备进行修改，提供了一种替代当前方法的方法，减少了监测 L. delicatula 的非目标捕获。
