Wolbachia pipientis is an endosymbiotic alpha-proteobacterium that is found in numerous insects and arthropods. Only a few studies have been made on Wolbachia in blood-sucking midges. In this study, we identified and determined the molecular characteristics of Wolbachia strains in Forcipomyia taiwana (Shiraki), a blood-sucking midge found in Taiwan and southern China. Our results indicate that all F. taiwana individuals captured in Nantou County, Taiwan were infected with Wolbachia strains closely related to the A-supergroup wAlbA. Moreover, 2 individuals captured at low-abundance locations were also infected with a B-supergroup Wolbachia strain. We observed that 63% F. taiwana individuals captured at the low-abundance locations harbored the wAlbA-like strain which has a particular substitution pattern (D51G, T84A, and A85V) in the Wolbachia surface protein. Taken together, our results indicate that distinct Wolbachia strains exist in F. taiwana populations in the field.
