摘要： Simple Summary Interest in large-scale rearing edible insects such as beetles, crickets, and flies has increased significantly in recent years. These insects are now used for various purposes: as food and feed, managing organic and plastic waste, detoxifying environments, producing biofuels, and even in cosmetics and pharmaceuticals. These applications consist of feeding insects with waste materials that are not widely used, transforming them into valuable products like food, feed, and fertilizer. The insect's digestive system is therefore the keystone of these developing processes. Digestion is partly carried out by the insect itself and partly by gut-associated microorganisms. Their respective roles remain a needed research area, and it is now clear that the community of microorganisms can adapt, enhance, and extend the insect's ability to digest and detoxify their feed. Despite this, these species are surprisingly autonomous, with no mandatory association with microorganisms required for digestion. On the contrary, microbiota largely differ for the same species, and are mostly shaped by the host's environment and diet. This natural flexibility offers the prospect of targeting and developing novel associations between insects and microorganisms to create mass-reared strains tailored to manage specific by-products and industrial applications.Abstract The interest in edible insects' mass rearing has grown considerably in recent years, thereby highlighting the challenges of domesticating new animal species. Insects are being considered for use in the management of organic by-products from the agro-industry, synthetic by-products from the plastics industry including particular detoxification processes. The processes depend on the insect's digestive system which is based on two components: an enzymatic intrinsic cargo to the insect species and another extrinsic cargo provided by the microbial community colonizing-associated with the insect host. Advances have been made in the identification of the origin of the digestive functions observed in the midgut. It is now evident that the community of microorganisms can adapt, improve, and extend the insect's ability to digest and detoxify its food. Nevertheless, edible insect species such as Hermetia illucens and Tenebrio molitor are surprisingly autonomous, and no obligatory symbiosis with a microorganism has yet been uncovered for digestion. Conversely, the intestinal microbiota of a given species can take on different forms, which are largely influenced by the host's environment and diet. This flexibility offers the potential for the development of novel associations between insects and microorganisms, which could result in the creation of synergies that would optimize or expand value chains for agro-industrial by-products, as well as for contaminants.
