Population and community ecology of the brown spruce longhorn beetle

随着全球贸易的增加，外来入侵森林昆虫已成为北美森林生态和经济严重干扰的因素。祖母绿灰螟（原产于远东）和棕色云杉长角甲虫（原产于东欧）是最近在加拿大东部建立的两种树木杀手昆虫。这些昆虫在其原生范围内不是害虫，但由于缺乏监管控制和允许种群爆炸的新生态相互作用，导致加拿大的树木死亡。我的研究调查的生态和行为的树木杀人昆虫，他们的宿主树木和天敌，了解为什么以及如何地方性种群转变为流行病的目标。

With increasing global trade, invasive alien forest insects have become agents of severe ecological and economic disturbance in North American forests. The emerald ash borer (native to the Far East) and the brown spruce longhorn beetle (native to Eastern Europe) are two examples of tree-killing insects that have recently established in Eastern Canada. These insects are not pests in their native range but cause tree mortality in Canada as a result of novel ecological interactions that lack regulatory controls and permit population explosions. My research investigates the ecology and behaviour of tree-killing insects, their host trees and natural enemies with the goal of understanding why and how endemic populations transition into epidemics.
