The intracellular endosymbiont bacterium Wolbachia is currently considered the most abundant in arthropods. Many Wolbachia manipulate host reproductive systems, it lead to male-killing, cytoplasmic incompatibility, parthenogenesis and feminization of genetic males with large impact on host ecology and evolution in arthropods. In this study, we investigated the distribution of Wolbachia infection in Ae. albopictus according to geographical distribution. We selected 9 areas and collected Ae. albopictus, these areas were distinguished with mountain chain and waterway. Whole genomic DNA were extracted from collected specimens and PCR analysis were accomplished in each specimen using Wolbachia specific primers such as 16S and WSP genes. As a results, we collected 730 Ae. albopictus at least 30 specimens in each area. Wolbachia infection rate showed different patterns between geographical region. Cheonbook, Cheonnam and Yeongdong showed 100% infection rate followed by Jeju (97%), Chungchung (88%), and Gyungnam (85%) with two Wolbachia marker genes. Our results indicated that Ae. albopictus are commonly infected with Wolbachia, it is possible that Wolbachia may act as endosymbiont in Ae. albopictus regardless of geographical region. Although, low infection rate of Wolbachia, we need continuous survey for the evaluation of Wolbachia strain within Ae. albopictus as a vector of dengue fever.
