A common complication in invasive pest management is that the infectious state of the host can be wrongly assessed, leading to biases in the estimation of the prevalence of the pest and on the efficacy of mitigation actions. We designed a multievent model that accommodates uncertainty on host state to investigate the dynamics of the infestation of Phoenix canariensis by the invasive Rhynchophorus ferrugineus. Since 2011, the council of Palma city (Mallorca Island, Spain) applied preventive, curative and destructive treatments to public Phoenix palms. A year later awareness campaigns focused on every palm owner in an attempt to control the plague. We estimated the probability of infestation and assessed the efficiency of mitigation measures, awareness campaigns and palm-dependent covariates. Our results show that infestation probabilities were higher for palms infested in the previous year than for healthy palms and it decreased substantially over time as a results of mitigation measures and awareness campaigns. Palms surrounded by treated palms had a lower probability of being infested than palms surrounded by untreated palms, i.e. private palms before awareness campaigns implementation. Our results highlight the key role of awareness campaigns and public participation for invasive species control.

侵入性有害生物管理中的一个常见并发症是宿主的感染状态可能被错误地评估，从而导致有害生物的流行程度估计和缓解措施的有效性存在偏差。我们设计了一个能够容纳宿主状态不确定性的多事件模型，以研究入侵的铁蓝藻侵染加拿大凤凰的动态。自2011年以来，帕尔马市议会（西班牙马洛卡岛）对凤凰城公众进行了预防，治疗和破坏性治疗手掌。一年后，提高意识运动的重点是每一个掌主，以控制鼠疫。我们估计了侵扰的可能性，并评估了缓解措施，意识运动和依赖棕榈的协变量的效率。我们的结果表明，上一年被侵染的棕榈的侵扰概率要比健康的棕榈高，并且由于缓解措施和提高意识的运动，侵扰概率随时间的推移而显着下降。与未经处理的棕榈树（即，在开展意识运动之前实施的私人棕榈树）所围绕的棕榈树相比，被经过处理的棕榈树所包围的棕榈树出没的可能性更低。我们的研究结果突出了意识活动和公众参与对入侵物种控制的关键作用。
