Bromeliads serve as a key environmental resource for Aedes albopictus (Skuse) in some peridomestic landscapes and are not addressed through conventional source reduction. As an alternative, three handheld sprayers were evaluated in point‐source applications of permethrin to bromeliads in Saint Augustine, FL. Each machine was screened for its utility in point‐source harborage treatments, while we simultaneously evaluated bromeliad‐focused treatments for reducing Ae. albopictus egg abundance in bromeliad plants. Semi‐field tests against caged Ae. albopictus produced 100% mortality at 24 h with each sprayer. Three field sites were assigned to each machine and a control, and bromeliad residual applications of Aqualuer 20‐20^® were assessed through egg surveillance using ovitraps both within and beyond 30 m of the treated bromeliad harborage. The treatment decreased Ae. albopictus egg abundance across the field sites for three weeks post‐treatment with no significant differences among the equipment. Functional differences among machines, such as automated pressure control or leak guards on the nozzle, depend on the accessories that offer the greatest logistical benefit to the user. The field results suggest bromeliads are a viable target for harborage treatments. Selective treatments to bromeliads could offer a possible solution to containers that homeowners refuse to eliminate.

使用三支手动喷雾器针对白纹伊蚊（Diptera：Culicidae）用Aqualuer®20-20进行Bromeliad靶向叶面处理，以减轻热点。

凤梨科动物在某些猪场景观中是白纹伊蚊（Skuse）的重要环境资源，不能通过常规的源头减少来解决。作为替代方案，在佛罗里达州圣奥古斯丁对氯菊酯在凤梨科的点源应用中对三台手持喷雾器进行了评估。筛选了每台机器在点源港口庇护处理中的效用，同时我们同时评估了以凤梨科为重点的减少Ae的处理方法。凤梨科植物中白带虫卵的丰度。对笼中Ae进行半场测试。每个喷雾器在24小时内白化病的死亡率为100％。三个网站被分配到每一台机器和控制，以及凤梨Aqualuer 20-20的残余应用^®通过卵监视法，在处理过的菠萝科动物栖息地30 m内及超过30 m的范围内，通过产卵器进行评估。治疗降低了Ae。治疗后三周，整个田间站点的白带虫卵丰度较高，设备之间无显着差异。机器之间的功能差异（例如自动压力控制或喷嘴上的防泄漏装置）取决于为用户提供最大后勤利益的附件。田间研究结果表明凤梨科植物是庇护治疗的可行目标。对凤梨科动物的选择性处理可能为房主拒绝淘汰的容器提供可能的解决方案。
