Abstract Microbes can be an important source of phenotypic plasticity in insects. Insect physiology, behaviour, and ecology are influenced by individual variation the microbial communities held within insect gut, reproductive organs, bacteriome, other tissues. It is becoming increasingly clear how microbiome for fitness, expansion into novel ecological niches, environments. These investigations have garnered heightened interest recently, yet a comprehensive understanding intraspecific assembly function these insect-associated shape insects still lacking. Most research focuses on core associated with species ignores variation. We argue that among driver evolution, we provide examples showing such influence fitness health insects, invasions, their persistence new environments, responses to global environmental changes.
