Abstract Background The interaction between gut bacterial symbionts and Tephritidae became the focus of several studies that showed bacteria contributed to nutritional status reproductive potential its fruit fly hosts. Anastrepha fraterculus is an economically important pest in South America. This currently controlled by insecticides, which prompt development environmentally friendly methods such as sterile insect technique (SIT). For SIT be effective, a deep understanding biology sexual behavior target species needed. Although many have this direction, little known about composition role A. symbiotic bacteria. In study we tested hypothesis contribute success males. Results AB affected community digestive tract , particular belonging Enterobacteriaceae family, was dominant group control flies (i.e., non-treated with AB). negatively parameters directly related mating laboratory males their status. also males’ survival under starvation conditions. effect on behaviour depended two additional factors: origin presence proteinaceous source diet. Conclusions Our results suggest contain organisms are able exert positive contribution fitness, although physiological mechanisms still need further studies.
