Isolation and identification of bacteria in the intestinal tract of adult Bactrocera tau(Walker)(Diptera:Tephritidae)

21 strains of bacteria were isolated and identified from the intestinal tract of sexually matured female Bactrocera tau which were reared in the laboratory using traditional isolation and 16 S r DNA( V6- V8 hypervariable region) sequencing technique. All bacteria strains belonged to the Gamma-proteobacteria phylum,which included Enterobacter( 7 strains),Raoultella( 3 strains),Serratia( 2 strains),Providencia( 2 strains),Acinetobacter( 1 strain),Citrobacter( 1 strain),Cedecea( 1 strain) and uncultured bacteria( 4 strains). Similarly,20 bacteria strains were isolated and identified from male B. tau and they also belonged to Gammaproteobacteria phylum,which consisted of bacteria( 7 strains),Klebsiella( 4 strains),Enterobacter( 3 strains),Providencia( 2strains),Serratia( 1 strain),Morganella( 1 strain),Pseudomonas( 1 strain) and gamma Proteobacterium( 1 strain). Bacteria genus which both females and males had in common were Enterobacter,Providencia and Serratia,which all belonged to Enterobacteriaceae. To summarize,Enterobacteriaceae was the dominant bacterium in intestinal tract of B. tau.
