摘要：昆虫作为媒介传播的林木病害在全球范围广泛分布,并造成毁灭性的危害。害虫和病原物对林木形成复合危害,因其发生机理复杂和危害症状隐蔽,以及二者间通过跨界互惠共生提高单个物种的适生度、增强对环境变化的缓冲适应能力和维持特定的生态功能等特点,使得对这类病虫复合危害的控制难度极大。小蠹虫(象甲科Curculionidae小蠹亚科Scolytinae)与真菌在长期协同进化过程中,形成了稳定的体外共生关系,这些真菌被称为小蠹虫的伴生真菌(associated fungi),其中许多种类能引起严重的森林病害,并与小蠹虫表现出密切的互惠共生关系。本文主要围绕小蠹虫和伴生真菌中了解最深入的长喙壳类真菌形成的伴生体系,从伴生真菌多样性、长喙壳类真菌生态功能和病虫复合危害防控展望3个方面,介绍相关领域的最新研究进展,为认识这类危害的作用机理积累科学基础,并为森林病虫害的有效控制提供新思路。
Insect-borne diseases are a class of major forest diseases that occur globally in epidemic proportions.Both insect pests and pathogens form synergetic infection to forest trees,which are extremely difficult to control due to the complexity of their mechanisms of occurrence,the insidious nature of damage symptoms,and mutualistic symbioses between insect pests and pathogens,which increase the fitness of each individual species,enhancing the buffering and adaptive capacity of species to environmental change,and maintaining specific ecological functions.Bark beetles(Curculionidae Scolytinae)and fungi have formed stable ectosymbiosis during the long-term co-evolution process.These fungi are called associated fungi of bark beetles,many of which can cause serious forest diseases and show close mutualistic symbioses with beetles.The present paper focuses primarily on the bark beetle-ophiostomatoid fungi companion system,which is the most well understood associated fungi,and provides an overview of the latest research progress in related fields from three perspectives,namely,the diversity of associated fungi,ecological functions of ophiostomatoid fungi,and prospect of strategies for prevention and control of the synergetic infection of insect pests and pathogens.It is hoped that the findings summarized in this review can aid in building a scientific basis for understanding the mechanisms of action of such damage and offer novel ideas for effective control of forest insect pests and pathogens.
