Abstract Laurel wilt and Fusarium dieback are vascular diseases caused by fungal symbionts of invasive ambrosia beetles (Coleoptera: Curculionidae: Scolytinae). Both diseases threaten avocado trees in Florida. Redbay ambrosia beetle, Xyleborus glabratus, is the primary vector of the laurel wilt pathogen, Raffaelea lauricola, but in recent years this symbiont has been transferred laterally to at least nine other species of ambrosia beetle, which now comprise a community of secondary vectors. Dieback disease, caused by Fusarium spp. fungi, is spread by shot hole borers in the Euwallacea fornicatus species complex. In this study, we conducted field tests in Florida avocado groves to compare efficacy of four trap designs for detection of Scolytinae. Treatments included an 8-funnel Lindgren trap, black 3-vane flight interception trap, green 3-vane interception trap, white sticky panel trap, and an unbaited sticky panel (control). In two tests targeting E. nr. fornicatus and X. glabratus, traps were baited with a two-component lure (α-copaene and quercivorol). In a test targeting other species, traps were baited with a low-release ethanol lure. For E. nr. fornicatus, sticky panels and black interception traps captured significantly more beetles than Lindgren traps; captures with green traps were intermediate. With ethanol-baited traps, 20 species of bark/ambrosia beetle were detected. Trap efficacy varied by species, but in general, sticky traps captured the highest number of beetles. Results indicate that sticky panel traps are more effective for monitoring ambrosia beetles than Lindgren funnel traps, the current standard, and may provide an economical alternative for pest detection in avocado groves.

用于检测 Euwallacea nr 的陷阱设计的比较。佛罗里达州鳄梨树的媒介真菌病原体 fornicatus 和其他 Scolytinae（鞘翅目： Curculionidae）

摘要 月桂枯萎病和枯萎病是由侵入性甘草甲虫（鞘翅目：Curculionidae：Scolytinae）的真菌共生体引起的血管疾病。这两种疾病都威胁着佛罗里达州的鳄梨树。Redbay ambrosia 甲虫 Xyleborus glabratus 是月桂枯萎病病原体 Raffaelea lauricola 的主要载体，但近年来，这种共生体已横向转移到至少 9 种其他物种的 ambrosia 甲虫，这些物种现在包括一个次要载体群落。枯萎病，由镰刀菌引起。真菌，由 Euwallacea fornicatus 物种复合体中的小孔蛀虫传播。在这项研究中，我们在佛罗里达州的鳄梨林中进行了现场测试，以比较四种捕集器设计在检测 Scolytinae 方面的功效。处理方法包括 8 漏斗 Lindgren 捕集器、黑色 3 叶片飞行拦截捕集器、绿色 3 叶片拦截捕集器、白色粘板捕集器和无诱饵粘板（对照）。在针对 E. nr. 的两项测试中。fornicatus 和 X. glabratus，用双组分诱饵（α-可巴烯和槲皮素）诱捕陷阱。在针对其他物种的测试中，诱捕器用低释放乙醇诱饵作为诱饵。对于 E. nr. fornicatus、粘性面板和黑色拦截陷阱捕获的甲虫明显多于 Lindgren 陷阱；带有绿色陷阱的捕获是中等的。使用乙醇诱饵诱捕器，检测到 20 种树皮甲虫。诱捕器的功效因物种而异，但总的来说，粘性诱捕器捕获的甲虫数量最多。结果表明，粘性面板陷阱比当前的标准 Lindgren 漏斗陷阱更有效地监测甘草甲虫，
