Because of the profound ecological and economic impacts of many non‐native insect species, early detection and eradication of newly founded, isolated populations is a high priority for preventing damages. Though successful eradication is often challenging, the effectiveness of several treatment methods/tactics is enhanced by the existence of Allee dynamics in target populations. Historically, successful eradication has often relied on the application of two or more tactics. Here, we examine how to combine three treatment tactics in the most cost‐effective manner, either simultaneously or sequentially in a multiple‐annum process. We show that each tactic is most efficient across a specific range of population densities. Furthermore, we show that certain tactics inhibit the efficiency of other tactics and should therefore not be used simultaneously; but since each tactic is effective at specific densities, different combinations of tactics should be applied sequentially through time when a multiple‐annum eradication programme is needed.

随着时间的推移结合多种策略，以经济有效的方式消灭入侵的昆虫种群

由于许多非本地昆虫物种对生态和经济产生了深远的影响，因此，尽早发现和根除新建立的孤立种群是防止损害的高度优先事项。尽管成功地根除通常面临挑战，但目标人群中Allee动态的存在增强了几种治疗方法/策略的有效性。从历史上看，成功的根除往往依赖于两种或多种战术的应用。在这里，我们研究了如何以最具成本效益的方式将三种治疗策略同时或在多个过程中相继进行。我们表明，在特定的人口密度范围内，每种策略都是最有效的。此外，我们表明某些策略会抑制其他策略的效率，因此不应同时使用。
