[Objective] The composition of symbiotic bacteria associated with Guava fruit fly, Bactrocera correcta（Bezzi）, was investigated to provide the basis for further study on physiological function of the symbionts and co-evolution between bacteria and the host. [Method] 16s rDNA libraries of laboratory population for B.correcta were constructed, and BLAST analysis of bacterial composition and abundance was carried out in this study. [Result] The dominant symbionts in B.correcta male adults were Pseudomonas aeruginosa and Lactococcus lactis, while symbiotic bacteria in female adults were Enterobacter bacteria. [Conclusion] Various bacteria are present in the Guava fruit fly, B.correcta.
