Abstract

Wolbachia is a widespread endosymbiont of insects with a diverse range of biological effects on its hosts. We studied the prevalence of Wolbachia in some important species of tephritids in Iran. Among different populations of five fruit fly species, Dacus ciliatus (cucurbit fly), Rhagoletis cerasi (cherry fruit fly), Ceratitis capitata (Mediterranean fruit fly), Myiopardalis pardalina (melon fly) and Carypomya vesuviana (jujube fly), two species, R. cerasi and C. vesuviana, showed infection with separate Wolbachia strains, namely wCer6 and wVes1, respectively. C. vesuviana is introduced here as a novel host for Wolbachia. Genotyping of Wolbachia strains in 12 populations of five fruit fly species, using multilocus sequence typing (MLST) and the wsp gene sequence showed the occurrence of two new strains as well as a new strain type (ST) belonging to the A supergroup. On the basis of the results of this study, 12 barcodes under five species of Iranian tephritids have been added to the database of DNA barcodes. Inter- and intra-specific differences among COI sequences showed a clear gap in barcoding among most fruit flies.
