Distinct assembly processes of intestinal and non-intestinal microbes of bark beetles from clues of metagenomic insights.

ABSTRACT: Ips (Curculionidae: Scolytinae) bark beetles (BBs) are ecologically and economically devastating coniferous pests in the Northern Hemisphere. Although the microbial diversity associated with these beetles has been well studied, mechanisms of community assembly and the functional roles of key microbes remain poorly understood. This study investigates the microbial community structures and functions in both intestinal and non-intestinal environments of five Ips BBs using a metagenomic approach. The findings reveal similar microbial community compositions, though the α-diversity of dominant taxa differs between intestinal and non-intestinal environments due to the variability in bark beetle species, host trees, and habitats. Intestinal microbial communities are predominantly shaped homogenizi
