Symbiotic microbiomes play important roles in hosts’ adaptation and evolution. Here, the gut bacterial communities in Cephalcia chuxiongica , a key pest of pines in China, were studied for the first time by using 16S rRNA amplicon sequencing. The composition of gut bacterial communities differed in different C. chuxiongica geographic populations but interestingly, the phylogeny and diversity of gut microbiota correlated with host geographic/genetic distance, that is the microbiota was more similar as the geographic/genetic distance decreased, and vice versa. The various microbes performed similar functions and showed functional complementation, in which most of identified KEGG pathways were shared by different populations with metabolism being the most dominant functional pathway and the function of major microbes associated with host dietary specialization (pine needles), such as cellulose degradation. In addition, some microbes also associated with host biological characteristics, such as Wolbachia with parthenogenesis and Serratia with the long‐term larval diapause in C. chuxiongica . Therefore, the synergy of environmental and host factors shapes the structure of gut microbiota and gut microbiota play essential roles in host physiology and adaptation, suggesting some kind of symbiosis and coevolution. These results demonstrate the important contribution of gut microbiota and provide a sound foundation for developing control strategies for this pest.
