Heavy metal pollution in the environment is mostly manifested as a multi-elemental compound pollution. The effect of long-term exposure to heavy on gut microbes insects has remained unknown. For current work, population Eucriotettix oculatus living mining areas around Diaojiang River with history hundreds years pollution, was selected along similar species non-mining conduct comparative study their microbes. microbial communities were analyzed using 16S rRNA amplicon sequencing. results showed Proteobacteria be dominant among E. oculatus, but abundance significantly increased when exposed symbiotic bacteria belonging genus Wolbachia found insect from area group, while pathogenic Aeromonas group. diversity analysis that community reduced habitat. differences and metabolic pathways two groups caused increase which might have negative impact health host. At same time, probiotics beneficial metabolism also enhance, helping host resist damage by stress. This one strategies used adapt
