树皮甲虫爆发和野火是北美西部森林变化的主要驱动力，近年来两者的严重程度和范围都有所增加。这两种干扰因素以复杂的方式相互作用，形成森林结构和组成。例如，山松甲虫，Dendroctonus ponderosae霍普金斯，流行病改变森林燃料的频率和强度的野火的后果，相反，火灾对树木的伤害可以促进树皮甲虫的攻击和增加甲虫种群。鉴于这些过程对森林生态系统的巨大影响，需要更好地了解树皮甲虫和火灾如何相互作用，以更好地管理森林，预测和管理野火。在这里，我们回顾目前的知识火和树皮甲虫相互作用，重点是山松甲虫。我们突出研究如何减少燃料处理和野火影响树皮甲虫和树皮甲虫如何通过修改燃料的水分含量，化学和结构来影响野火。最后，我们讨论了这些研究结果对消防管理和消防员安全的影响。
Bark beetle outbreaks and wildfires are principal drivers of change in western North American forests, and both have increased in severity and extent in recent years. These two agents of disturbance interact in complex ways to shape forest structure and composition. For example, mountain pine beetle, Dendroctonus ponderosae Hopkins, epidemics alter forest fuels with consequences for the frequency and intensity of wildfires and, conversely, fire injury to trees can promote bark beetle attack and increase beetle populations. Given the great influence these processes have on forest ecosystems, a better understanding of how bark beetles and fires interact is needed to better manage forests and to predict and manage wildfires. Here we review current knowledge on how fire and bark beetles interact, focusing on the mountain pine beetle. We highlight research on how fuel reduction treatments and wildfires affect bark beetles and how bark beetles can affect wildfires by modifying the moisture content, chemistry, and structure of fuels. Last, we discuss the implications these findings have for fire management and firefighter safety.
