Distinct gut bacterial communities between A. cerana and A. mellifera. The Chao1 richness (a) and phylogenetic diversity (b) of A. mellifera gut bacterial communities were higher than those of A. cerana. (c) Nonmetric multidimensional scaling (NMDS) profiling illustrated distinct gut bacterial communities between A. cerana and A. mellifera. (d) Comparison of gut bacterial similarities within A. cerana, within A. mellifera, and between host species. (e) Phylogenetic tree of the 81 operational taxonomic units (OTUs) with a relative abundance of >0.1% in at least one sample, where the core OTUs within A. cerana and A. mellifera guts were labeled with red and blue circles, respectively. Bars showed the mean relative abundance of the OTUs. (f) The bootstrap consensus tree of the COI-COII haplotypes observed in this study and the correspondence to 100 honeybee samples. Branches with less than 50% bootstrap replicates were collapsed. Numbers on the edges of the tree represent the bootstrap values.
