Impact of the insect gut microbiota on ecology, evolution, and industry

Insects harbor diverse microorganisms in the gut, providing their host with physiological and ecological advantages. For example, gut symbionts contribute to detoxification in phytophagous insects, degradation of lignocellulose in xylophagous insects, and in many insects, protection from pathogens by producing antimicrobial compounds. Furthermore, an unexpected function of the insect gut microbiota has been discovered-plastic degradation. Based on these diverse abilities of the insect gut microbiota that have been sophisticated under the natural environment, recent studies have aimed at applying the potential of gut microbes in the medical, engineering, and industrial fields.
