红脂大小蠹是我国重要的外来入侵害虫,给我国林业生产和国土生态安全带来巨大危害。包括红脂大小蠹在内的小蠹科昆虫与真菌之间存在着广泛的共生关系,伴生菌在协助昆虫建立种群、协同克服寄主抗性等方面起到重要作用。对北美原发地红脂大小蠹伴生菌的研究进行综述,以期探讨引起灾害发生的多重因素,并为灾害的控制提供思路。红脂大小蠹记载与10种长喙壳类真菌伴生,其中黑脂小蠹细帚霉、长梗细帚霉、温菲尔德细帚霉和瓦格纳长喙壳等与红脂大小蠹有着较为紧密的共生关系。对这些主要伴生菌的形态特征、系统发育关系、生活习性和致病性进行详细比较。应当警惕这些重要森林病原物对我国森林生态系统的入侵和危害。并对今后包括红脂大小蠹伴生菌在内的我国小蠹虫伴生菌的研究进行讨论。
Red beetle beetle is an important invasive pest in our country, which brings great harm to our country’s forestry production and national ecological security. There is a wide symbiotic relationship between the moth and the fungus, including the red beetle, and the accompanying bacteria play an important role in assisting the insect to establish the population and collaborating to overcome host resistance. In this paper, the primary research on the companion bacteria of Rhododendron gossypii in North America is reviewed in order to explore the multiple factors that cause the disaster and provide ideas for the control of the disaster. The red beetles were recorded with 10 species of long-beaked shellfish fungi, of which, the black gypsophila spp., The long slender gilts, the slender wenflinger wagner and Wagner’s long-beaked shell and the red beetles have a relatively close Symbiotic relationship. Morphological characteristics, phylogenetic relationships, living habits and pathogenicity of these major companion bacteria were compared in detail. We should be wary of the invasion and damage to these forest ecosystems by these important forest pathogens. In the future, we will discuss the research on the associated beetles in our country, including the companion bacteria of Red Beetle.
