BackgroundRoof rats (Rattus rattus) are a substantial pest throughout citrus crops, yet little is known about efficacious, cost‐effective strategies to manage this rodent. Therefore, we developed two integrated pest management (IPM) programs that incorporated elevated bait stations containing diphacinone‐treated oats and trapping, and we compared those programs to a bait‐station only approach to determine which strategies were most practical for the management of roof rats in citrus orchards.ResultsBait applications substantially reduced rat activity within orchards. However, our initial IPM approach that used a combination of baiting, snap trapping and Goodnature® A24 traps were not successful at keeping rats from rapidly repopulating. A second IPM strategy that relied on baiting and more extensive snap trapping was effective at reducing rat activity up to, and likely beyond, a 6‐month treatment period. Although baiting by itself was less expensive than IPM plots, the difference in cost between baiting and the IPM approach that used only baiting and snap trapping should be minimal during long‐term management programs.ConclusionThe high efficacy of a management program that incorporates an initial bait application, followed by a long‐term snap‐trapping program, should yield effective management of roof rats in citrus orchards. © 2025 The Author(s).

测试管理柑橘园屋顶老鼠的综合方法



背景屋顶鼠 (Rattus rattus) 是柑橘类作物中的重要害虫,但人们对管理这种啮齿类动物的有效、具有成本效益的策略知之甚少。因此,我们开发了两个综合害虫管理 (IPM) 计划,其中包括包含地帕西农处理燕麦的高架诱饵站和诱捕,并将这些计划与仅诱饵站的方法进行比较,以确定哪些策略对于管理柑橘园的屋顶鼠最实用。结果诱饵应用大大减少了果园内的大鼠活动。然而,我们最初的 IPM 方法结合使用诱饵、快速诱捕和 Goodnature® A24 诱捕器,并不能成功地阻止大鼠快速重新繁殖。第二种 IPM 策略依赖于诱饵和更广泛的快速诱捕,可有效减少大鼠活动,直至并可能超过 6 个月的治疗期。尽管诱饵本身比 IPM 图便宜,但在长期管理计划中,诱饵与仅使用诱饵和快速诱捕的 IPM 方法之间的成本差异应该是最小的。结论包含初始诱饵应用和长期捕捉计划的管理计划的高效率应该可以有效地管理柑橘园中的屋顶鼠。© 2025 作者。由John Wiley & Sons Ltd代表化学工业协会出版的《害虫管理科学》。本文由美国政府雇员提供,他们的工作在美国属于公共领域。
