白蜡木窄吉丁（Agrilusplanipennis（Fairmaire），鞘翅目：吉丁科）是一种重要的害虫，对北美城市森林中白蜡木的健康和管理起着重要的作用。对管理方案进行了经济分析，以帮助决策者为未来可能发生的虫害做好准备。单独的白蜡树种群估值来自i树街道计划和树木和景观评估师理事会（CTLA）的方法。一个相对的经济分析被用来比较控制选项（什么都不做的方法，只删除灰树，因为他们死了），三个不同的管理选项：1）先发制人的删除所有灰树超过5年的时间，2）先发制人的删除所有灰树和替代可比nonash树，或3）处理整个人口的灰树与杀虫剂，以尽量减少死亡率。对于每一个估值和管理方案，对剩余的白蜡树种群和因绿白蜡虫而损失的种群进行了年度分析。保留白蜡树使用杀虫剂处理通常保留更大的城市森林价值，其次是什么都不做（控制），这是优于先发制人的删除和更换。在20年的模拟中，不更换树木的先发制人的清除是最便宜的管理选择，也提供了最低的城市森林净价值。一个“没有绿白蜡螟”的情况下，建模，以进一步作为每个管理选项的基准，并提供了一个经济合理的监管计划，旨在减缓绿白蜡螟的运动水平。
ABSTRACT Emerald ash borer, Agrilus planipennis (Fairmaire) (Coleoptera: Buprestidae), plays a significant role in the health and extent of management of native North American ash species in urban forests. An economic analysis of management options was performed to aid decision makers in preparing for likely future infestations. Separate ash tree population valuations were derived from the i-Tree Streets program and the Council of Tree and Landscape Appraisers (CTLA) methodology. A relative economic analysis was used to compare a control option (do-nothing approach, only removing ash trees as they die) to three distinct management options: 1) preemptive removal of all ash trees over a 5 yr period, 2) preemptive removal of all ash trees and replacement with comparable nonash trees, or 3) treating the entire population of ash trees with insecticides to minimize mortality. For each valuation and management option, an annual analysis was performed for both the remaining ash tree population and those lost to emerald ash borer. Retention of ash trees using insecticide treatments typically retained greater urban forest value, followed by doing nothing (control), which was better than preemptive removal and replacement. Preemptive removal without tree replacement, which was the least expensive management option, also provided the lowest net urban forest value over the 20-yr simulation. A “no emerald ash borer” scenario was modeled to further serve as a benchmark for each management option and provide a level of economic justification for regulatory programs aimed at slowing the movement of emerald ash borer.
