Uninheritable but Widespread Bacterial Symbiont Enterococcus casseliflavus Mediates Detoxification of the Insecticide Chlorantraniliprole in the Agricultural Invasive Pest Spodoptera frugiperda

Host-symbiont interaction plays a crucial role in determining the host's fitness under toxic stress, as observed in numerous insect species. However, the mechanism of the symbionts involved in the detoxification of insecticides remains poorly known. In this study, through microbiome, proteomic, and genomic analysis, we identified a prevalent symbiont,
