Since its accidental introduction from Asia, emerald ash borer (EAB), Agrilus planipennis Fairmaire (Coleoptera: Buprestidae), has killed millions of ash trees in North America. As it continues to spread, it could functionally extirpate ash with devastating economic and ecological impacts. Little was known about EAB when it was first discovered in North America in 2002, but substantial advances in understanding of EAB biology, ecology, and management have occurred since. Ash species indigenous to China are generally resistant to EAB and may eventually provide resistance genes for introgression into North American species. EAB is characterized by stratified dispersal resulting from natural and human-assisted spread, and substantial effort has been devoted to the development of survey methods. Early eradication efforts were abandoned largely because of the difficulty of detecting and delineating infestations. Current management is focused on biological control, insecticide protection of high-value trees, and integrated efforts to slow ash mortality.
自从 Emerald Ash Borer（EAB）意外地从亚洲引入以来，它已经杀死了北美的数百万棵灰树。随着它的继续传播，它可能会在功能上根除灰树，造成毁灭性的经济和生态影响。2002 年首次在北美发现 EAB 时，人们对它知之甚少，但自那时以来，对 EAB 生物学、生态学和管理的理解已经取得了实质性的进展。原产于中国的灰树种类通常对 EAB 具有抗性，并且最终可能为北美物种的基因渗入提供抗性基因。EAB 的特点是由于自然和人为传播而导致的分层扩散，并且已经投入了大量的努力来开发调查方法。早期的根除努力基本上因为难以检测和划定虫害而被放弃。目前的管理重点是生物防治、杀虫剂保护高价值树木以及综合努力减缓灰树死亡率。
