Abstract

Purpose of Review

To describe how general prescriptions to protect temperate and boreal forests against pests have been affecting the conservation of insect diversity, (2) to identify potential conflicts between biodiversity conservation actions and pest control, and (3) to provide future directions to reconcile forest pest management with insect conservation.

Recent Findings

Despite dealing with the same habitats and organisms, forest pest management and insect conservation have been separate disciplines, often pursuing conflicting goals. However, there is a large intersection between the two, as interventions to control pests can have repercussions on biodiversity and vice versa. In several regions, forest pest management is shifting from reactive measures to contain on-going outbreaks to proactive strategies to create forest landscapes that are more resistant and resilient against pests in the long-term. These developments suggest a possible convergence between pest management and insect conservation objectives.

Summary

Several reactive measures adopted to control pests can cause negative impacts on non-target insects, although effects are sometimes localized and often context-dependent. Following ecological, economic, and social considerations, pest management has been evolving towards diversifying forests across multiple spatial scales to reduce the severity of outbreaks and the risk of damage. Such strategies concur with multiple conservation goals to increase insect diversity across intensive forest landscapes. Insect conservation has traditionally targeted saproxylic organisms, neglecting the conservation of other insect guilds and seldom assessing side effects on pests. Despite some important knowledge gaps, we propose complementary approaches to combine multiple diversification strategies at the landscape scale to reconcile pest management with insect conservation.

协调温带和北方森林害虫管理与昆虫保护的战略与障碍
综述目的描述保护温带和北方森林免受害虫侵害的一般规定如何影响昆虫多样性的保护,(2) 识别生物多样性保护行动与害虫控制之间的潜在冲突,(3) 为协调森林害虫管理与昆虫保护提供未来方向。然而,这两者之间存在很大的交叉,因为控制害虫的干预措施会对生物多样性产生影响,反之亦然。在一些地区,森林害虫管理正从遏制虫害持续爆发的被动措施转变为积极主动的战略,以创造长期而言对害虫更具抵抗力和复原力的森林景观。这些发展表明,害虫管理与昆虫保护目标之间有可能趋于一致。摘要为控制害虫而采取的一些被动措施可能会对非目标昆虫造成负面影响,尽管影响有时是局部的,而且往往取决于具体情况。出于生态、经济和社会方面的考虑,害虫管理正朝着在多个空间尺度上实现森林多样化的方向发展,以降低虫害爆发的严重程度和损害风险。这种策略与多种保护目标一致,即在密集的森林景观中增加昆虫多样性。昆虫保护历来以脂腺昆虫为目标,忽视了对其他昆虫类群的保护,也很少评估对害虫的副作用。尽管存在一些重要的知识差距,我们还是提出了在景观尺度上结合多种多样化策略的互补方法,以协调害虫管理与昆虫保护之间的关系。

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.
