AAB massively colonized the insect gut with infection rates of 90 and 92% in fruit-fed and artificial diet-fed individuals, respectively. 16S rRNA gene pyrosequencing showed a differentiation of the bacterial microbiota of guts from insects fed with the two diets. The exclusion of AAB-related OTUs from the analysis showed a lack of the clustering pattern, suggesting that the diet-based diversification of the community is primarily reflected on AAB components. AAB alpha-diversity was also influenced by diet. Data suggested an AAB role in the gut response of D. suzukii to diet modification
