The hibiscus bud weevil (HBW), Anthonomus testaceosquamosus Linell (Coleoptera: Curculionidae), is a significant threat to tropical hibiscus (Hibiscus rosa-sinensis) in Florida, USA, since its invasion in 2017. As a regulated pest in the state, early detection is crucial. Based on the success of pheromone-based monitoring programs for other weevil pests, such as the boll weevil, cranberry weevil, and pepper weevil, this study explores the potential use of these pheromone lures for early detection of HBW. To account for differences in efficacy based on trap color, height, and design, different pheromone lure sizes (4 mm, 10 mm, full-size), trap types (Yellow sticky trap, Japanese beetle trap, Boll weevil trap), and heights (0 m, 1.1 m) were also tested in this study. In laboratory assays, males and females exhibited higher attraction to full-size cranberry weevil lure discs than other lure size-type combinations. In semi-field trials, yellow sticky traps baited with cranberry weevil lures captured more weevils than Japanese beetle or boll weevil traps baited with cranberry weevil lures, while trap height did not influence HBW capture. In semi-field, 4-choice bioassays, yellow sticky traps baited with cranberry weevil lures captured more HBW compared to yellow sticky traps baited with pepper weevil, boll weevil, or unbaited traps. Further research is required to thoroughly evaluate the cranberry weevil lure's efficacy in capturing HBW. Our study suggests the potential for utilizing yellow sticky traps baited with lures for early HBW detection and highlights the importance of selecting the appropriate lure, trap type, and height for optimal efficacy.
木槿芽象甲（HBW），即Anthonomus testaceosquamosus Linell（鞘翅目：象甲科），自2017年入侵以来，对美国佛罗里达州的热带木槿（Hibiscus rosa-sinensis）构成了重大威胁。作为该州的管制害虫，早期检测至关重要。基于针对其他象甲害虫（如棉铃象甲、蔓越橘象甲和胡椒象甲）的基于性信息素的监测计划的成功经验，本研究探索了这些性信息素诱捕器用于早期检测木槿芽象甲的潜力。为了考虑基于诱捕器颜色、高度和设计的功效差异，本研究还测试了不同的性信息素诱捕器尺寸（4毫米、10毫米、全尺寸）、诱捕器类型（黄色粘虫板、日本金龟子诱捕器、棉铃象甲诱捕器）和高度（0米、1.1米）。在实验室测定中，雄性和雌性对全尺寸蔓越橘象甲诱捕盘的吸引力高于其他诱捕器尺寸 - 类型组合。在半田间试验中，用蔓越橘象甲诱捕器诱捕的黄色粘虫板捕获的象甲比用蔓越橘象甲诱捕器诱捕的日本金龟子或棉铃象甲诱捕器更多，而诱捕器高度不影响木槿芽象甲的捕获量。在半田间四选生物测定中，用蔓越橘象甲诱捕器诱捕的黄色粘虫板捕获的木槿芽象甲比用胡椒象甲、棉铃象甲诱捕器诱捕的黄色粘虫板或未放置诱捕器的黄色粘虫板更多。需要进一步研究以全面评估蔓越橘象甲诱捕器在捕获木槿芽象甲方面的功效。我们的研究表明利用带有诱捕器的黄色粘虫板进行木槿芽象甲早期检测的潜力，并强调选择合适的诱捕器、诱捕器类型和高度以实现最佳功效的重要性。
