摘要: 昆虫在某些发育阶段可感染不同种类的共生微生物,这些共生物在宿主生长、繁殖、适应环境及进化的过程中起重要作用。大量研究发现,昆虫体内的不同共生微生物并不是孤立存在和发生作用的,而是相互间不同程度地存在某些联系。本文以共生细菌为重点,综述了最近10多年来有关不同种共生细菌之间的关系,及共生细菌与其他昆虫相关微生物(病原细菌、真菌和病毒及昆虫共生真菌)之间相互关系的研究进展。其中,重点回顾了不同细菌在昆虫体内的共存和对宿主功能上的协作,昆虫中已经发生或可能正在发生的细菌取代,以及共生细菌对宿主的病原物敏感性的影响等方面的研究。最后对各种生物学技术大量应用于共生细菌研究的背景下此领域的研究前景进行了讨论。

Abstract: Insects always harbor diverse microbial symbionts at certain development stages, which play significant roles in growth, reproduction, and adaption to environments and coevolution with their hosts. As demonstrated in numerous studies, these symbionts do not stay or work alone but instead have established certain relationships with each other. Here we reviewed the major findings reported in the past decade regarding interactions among symbiotic bacteria of various groups, as well as the relations between symbiotic bacteria and other microbes including bacterial, fungal and virus pathogens and fungal symbionts. We focused on the cooperation between co-infecting symbiotic bacteria that complementarily confer beneficials to hosts, realized or possibly ongoing replacement of bacteria by the ones more recently infecting insects, and effects of bacterial symbionts on the susceptibility of hosts to pathogens. The research prospects on symbiotic bacteria were discussed with the consideration of applying various biotechnology in this field.

Key words: bacteria, symbiotic systems, bacterial replacement, pathogens, biological control
