Facultative intracellular symbionts like the α-proteobacteria influence their insect host phenotype but little is known about how much they affect their host microbiota. Here, we quantified the impact of infection on the bacterial community of the cabbage root fly by comparing the microbiota of -free and infected adult flies of both sexes. We used high-throughput DNA sequencing (Illumina MiSeq, 16S rRNA, V5-V7 region) and performed a community and a network analysis. In both sexes, infection significantly decreased the diversity of bacterial communities and modified their structure and composition by reducing abundance in some taxa but increasing it in others. Infection by was negatively correlated to 8 bacteria genera ( was the most impacted), and positively correlated to and . We suggest that might antagonize for being entomopathogenic (and potentially intracellular), but would favor and because they might protect the host against chemical plant defenses. Although they might seem prisoners in a cell, endocellular symbionts can impact the whole microbiota of their host, hence its extended phenotype, which provides them with a way to interact with the outside world.
