Symbiotic Microorganisms Associated with Pentatomoidea 655
FIGURE 14.2 Phylogenetic tree based on the sequence of the 16S rRNA gene (neighbor-joining analysis). Bacterial
phyla/classes are shown on the right side. Symbiotic bacteria of pentatomomorphan species are represented in boldface,
and stink bug families are shown in parentheses. Abbreviations: GS, gut symbiont; IS, intracellular symbiont. Asterisks
indicate symbiotic bacteria of other insect groups. Several symbionts of stink bugs and other insects have been microbio-
logically characterized and named, whose host insects are informed in brackets. Bootstrap supporting values higher than
60% are depicted at the nodes. The scale bar represents 0.05 changes per base.
