Abstract

Purpose of Review

The invasion of North America by the Asian beetle Agrilus planipennis has caused severe economic and ecological damage to ash (Fraxinus) tree populations. Agrilus planipennis has recently entered eastern Europe and is spreading there. Many other Agrilus species can potentially become invasive pests due to the cryptic nature of their immature stages that can be inconspicuously transported within infested plant material. We review the ecology, economic impacts, and management strategies of Agrilus worldwide and highlight research gaps.

Recent Findings

Much has been learned in recent decades about the basic biology and control tactics for a few Agrilus species, especially A. planipennis.

Summary

The genus Agrilus has over 3,341 described species, making it the largest genus in the Animal Kingdom. Most Agrilus are univoltine and have a narrow host range. Chemical, tactile, and visual cues of host plants are used by adult Agrilus to select suitable hosts for consumption by adults and larvae. Most Agrilus larvae develop within the cambial region, constructing galleries that effectively girdle the host plant. Mechanisms of host plant resistance are being explored. Diverse groups of natural enemies attack all life stages of Agrilus species, with some coevolved specialist parasitoids being introduced successfully to suppress A. planipennis in North America. Climate change, leading to warmer and drier conditions, will influence the distribution and population dynamics of many Agrilus species. Many research gaps still exist in the areas of biocontrol, host plant resistance, and sustainable management strategies for this important group of plant pests.

Agrilus 甲虫的生态、经济和管理

综述目的亚洲甲虫 Agrilus planipennis 入侵北美对白蜡树（Fraxinus）种群造成了严重的经济和生态破坏。Agrilus planipennis 最近已进入东欧，并正在那里蔓延。许多其他 Agrilus 种类都有可能成为入侵害虫，因为它们的幼虫阶段具有隐蔽性，可以在受侵染的植物材料中不显眼地传播。我们回顾了全球 Agrilus 的生态学、经济影响和管理策略，并强调了研究缺口。最近的研究结果近几十年来，人们已经了解了一些 Agrilus 物种（尤其是 A. planipennis）的基本生物学特性和防治策略。大多数 Agrilus 为单伏性，寄主范围狭窄。成虫利用寄主植物的化学、触觉和视觉线索选择合适的寄主，供成虫和幼虫食用。大多数 Agrilus 幼虫在骨皮层区域内发育，构建的虫道可有效地束缚寄主植物。目前正在探索寄主植物的抗性机制。多种多样的天敌攻击 Agrilus 物种的各个生命阶段，一些共同进化的专业寄生虫被成功引入北美，以抑制 A. planipennis。气候变化导致气候更加温暖干燥，将影响许多 Agrilus 物种的分布和种群动态。在生物防治、寄主植物抗性以及针对这类重要植物害虫的可持续管理策略方面，仍存在许多研究空白。

期刊介绍： Current Forestry Reports features in-depth review articles written by global experts on significant advancements in forestry. Its goal is to provide clear, insightful, and balanced contributions that highlight and summarize important topics for forestry researchers and managers. To achieve this, the journal appoints international authorities as Section Editors in various key subject areas like physiological processes, tree genetics, forest management, remote sensing, and wood structure and function. These Section Editors select topics for which leading experts contribute comprehensive review articles that focus on new developments and recently published papers of great importance. Moreover, an international Editorial Board evaluates the yearly table of contents, suggests articles of special interest to their specific country or region, and ensures that the topics are up-to-date and include emerging research.
