摘　　要：Microorganisms prov ide many physiological functions to herbivorous hosts.Spider mites(genus Tetranychus)are important agricultural pests throughout the world;however,the composition of the spider mite microbial community,especially gut micro-biome,remains unclear.Here,we investigated the bacterial community in five spider mite species and their associated feces by deep sequencing of the 16S rRNA gene.The composi-tion of the bacterial community was significantly different among the five prevalent spider mite species,and some bacterial symbionts showed host-species specificity.Moreover,the abundance of the bacterial community in spider mite feces was significantly higher than that in the corresponding spider mite samples.However,Flavobacterium was detected in all samples,and represent a"core microbiome".Remarkably,the maternally inherited endosymbiont Wolbachia was detected in both spider mite and feces.Overall,these results offer insight into the complex community of symbionts in spider mites,and give a new direction for future studies.
