摘　　要：内共生菌(Endosymbionts)与其昆虫宿主的生物学特性联系非常密切。近年来,昆虫内共生菌水平传播的途径及机制已经成为昆虫学研究的热点之一。越来越多的研究表明,亲缘关系相距甚远的昆虫可以感染有相同或相似的内共生菌,说明昆虫内共生菌的水平传播在自然界中普遍存在。植物介导的昆虫内共生菌水平传播便是其中的一条途径,即同种或不同种类的昆虫可以通过取食,获得供体昆虫传入植物组织中的内共生菌,形成内共生菌从供体昆虫-寄主植物-受体昆虫传播的路径。本文主要以植物介导的昆虫内共生菌水平传播途径为对象,介绍了昆虫内共生菌的水平传播途径,以及内共生菌传入后对新宿主生物学、生态学特性的影响,以期为昆虫内共生菌水平领域的研究提供更多有价值的参考。Endosymbionts are closely adapted to the biology of their insect hosts.In recent years,the routes and mechanisms involved in the horizontal transmission of insect endosymbionts has been an important topic in entomological research.A growing number of studies have revealed that insects with no close taxonomic affinity are infected with the same,or similar,endosymbionts.This indicates that horizontal transmission of insect endosymbionts is ubiquitous in nature,and that plant-mediated horizontal transmission of insect endosymbionts is a pathway for this.Recipient insects either of the same,or different,species can acquire endosymbionts from infected host plants;i.e.endosymbionts are transmitted from source insects to recipients via host plants.This paper reviews the mechanisms and processes involved in the plant-mediated horizontal transmission of insect endosymbionts,as well as the biological and ecological effects of endosymbionts on recipient hosts.We hope this review will provide a valuable reference for research on insect endosymbionts and pest control.
