中文摘要:共生菌参与昆虫宿主的多种生理活动,而昆虫则为共生菌提供了良好的增殖环境,两者互利共生。共生菌的种类、丰度和功能均因昆虫种类和发育阶段的不同而有所差异。该文总结了昆虫共生菌研究概况及已报道的昆虫共生菌种类,重点介绍了共生菌调控昆虫宿主生长发育和生殖的研究进展,包括共生菌通过协助宿主营养代谢及抵御病原菌来调控宿主的生长发育速率;胞内共生细菌沃尔巴克氏体Wolbachia通过胞质不亲和、雌性化、雄性致死以及诱导孤雌生殖调控宿主的生殖力;胞外共生细菌则通过参与宿主营养代谢、改变宿主生殖行为和影响宿主生殖细胞来调控昆虫宿主的生殖力,以及共生菌调控宿主生殖的可能分子机制。同时,该文还在深入探讨共生菌功能、拓宽研究宿主种类及共生菌在抗菌防虫中的应用等方面进行了展望。共生菌对昆虫宿主生长发育和生殖调控作用的研究有助于进一步揭示昆虫与共生菌的协同进化机制,并为进一步利用共生菌进行害虫治理奠定理论基础。

Abstract:Symbionts can take part in multitudinous physiological activities in insect hosts, and the insects can provide symbiotic microorganisms proper multiplication conditions. They are mutually beneficial. The species, abundance and function of symbiotic bacteria vary with the species and developmental stage of insects. In this review, the research advances in and the reported species of the insect symbiotic microorganisms were summarized, with emphases on the research progress in the symbiotic microorganisms regulating the growth, development and reproduction of insect hosts. Symbionts can regulate the growth and development of host insects by assisting host nutritional metabolism and resisting pathogenic bacteria. Wolbachia regulates host fecundity through cytoplasmic incompatibility, feminization, male death and parthenogenesis induction. Extracellular symbiotic bacteria regulate the fecundity of insect hosts by participating in host nutritional metabolism, changing host reproductive behavior and influencing host germ cells. The possible molecular regulatory mechanisms of host reproduction by symbiotic bacteria were also introduced. At the same time, the functions of symbionts, the broadening of host species and the application of symbionts in insect control were also discussed. The research on the regulation of insect host growth, development and reproduction by symbionts help to further reveal the mechanism of co-evolution between insects and symbionts, and lay a theoretical foundation for further use of symbionts in pest management.
