Abstract The spotted lanternfly, Lycorma delicatula (White), an invasive, phloem-feeding fulgorid generalist, was recently discovered in the United States. Current trapping methods include placing glue-covered sticky bands around trunks of host trees to exploit the lanternfly's behavior of climbing up tree trunks. These bands are messy and need to be replaced often as they become covered in both target and nontarget insects and debris. Fourth instar nymphs and adults have also shown an ability to escape from traditional tree bands or avoid capture. A promising commercially available tree band (BugBarrier) design that faces inward to the trunk and targets larger developmental stages was tested. A modified pecan weevil trap (circle trunk trap) was also compared with tree bands. This design does not require the use of insect-trapping adhesive. Circle trunk traps caught more third and fourth instar and adult L. delicatula than BugBarrier bands. Flight intercept traps caught fewer adult L. delicatula than trunk-based tree bands. In a separate comparison, more spotted lanternflies were caught on adhesive-coated ‘tree mimicking’ traps placed along the edges of Ailanthus altissima Swingle (Sapindales: Simaroubaceae) stands than away from hosts in an open field. Circle trunk traps are recommended for their effectiveness at capturing L. delicatula as well as their relative ease-of-use and reusability.

为斑点灯笼蝇开发陷阱，Lycorma delicatula（半翅目：Fulgoridae）

摘要 斑点灯笼蝇 Lycorma delicatula (White) 是一种侵入性的、以韧皮部为食的 fulgorid 通才，最近在美国被发现。目前的诱捕方法包括在寄主树的树干周围放置涂有胶水的粘性带，以利用灯笼蝇爬上树干的行为。这些条带很脏，需要经常更换，因为它们被目标和非目标昆虫和碎片覆盖。四龄若虫和成虫也表现出逃离传统树带或避免捕获的能力。测试了一种有前途的商用树带 (BugBarrier) 设计，该设计面向树干并针对更大的发育阶段。改良的山核桃象鼻虫诱捕器（圆形树干诱捕器）也与树带进行了比较。这种设计不需要使用诱虫粘合剂。圆形树干陷阱比 BugBarrier 带捕获了更多的三龄和四龄和成年 L. delicatula。飞行拦截陷阱捕获的成年 L. delicatula 比基于树干的树带捕获的更少。在单独的比较中，更多的斑点灯笼蝇被贴在沿臭椿（Sapindales： Simaroubaceae）边缘放置的粘合剂涂层“模仿树”陷阱中捕获，而不是在开阔的田野中远离宿主。推荐使用圆形树干陷阱，因为它们在捕获 L. delicatula 方面非常有效，并且相对易于使用和可重复使用。在沿臭椿（Sapindales： Simaroubaceae）立地边缘放置的涂有粘合剂的“树模仿”陷阱上捕获的斑点灯笼蝇比在开阔的田野中远离宿主的数量多。推荐使用圆形树干陷阱，因为它们在捕获 L. delicatula 方面非常有效，并且相对易于使用和可重复使用。在沿臭椿（Sapindales： Simaroubaceae）立地边缘放置的涂有粘合剂的“树模仿”陷阱上捕获的斑点灯笼蝇比在开阔的田野中远离宿主的数量多。推荐使用圆形树干陷阱，因为它们在捕获 L. delicatula 方面非常有效，并且相对易于使用和可重复使用。
