Abstrakt: Wolbachia is a ubiquitous endosymbiotic bacterium that manipulates insect reproduction. A notable feature of Wolbachia is male killing (MK), whereby sons of infected females are killed during development; however, the evolutionary processes by which Wolbachia acquired the MK ability remain unclear. The tea tortrix moth Homona magnanima (Tortricidae) harbours three non-MK Wolbachia strains (wHm-a, wHm-b and wHm-c) and an MK strain wHm-t. Although wHm-t and wHm-c are closely related, only wHm-t has an MK-associated prophage region. To understand the evolutionary processes underlying the emergence of MK wHm-t, we examined Wolbachia infections and phenotypes in 62 tortricid species collected from 39 localities across Japan, Taiwan, Vietnam and Indonesia. PCR assays detected wHm-c relatives in 51 species and triple infection of wHm-a, wHm-b and wHm-c in 31 species. Apart from Taiwanese H. magnanima, no species exhibited the MK phenotype and were positive for the wHm-t-specific prophage. While wHm-t infection was dominant in Taiwanese H. magnanima, wHm-a, wHm-b and wHm-c were dominant in Japanese H. magnanima populations. These results suggest that wHm-a, wHm-b and wHm-c strains descended from a common ancestor with repeated infection loss and that wHm-t evolved from the wHm-c acquiring MK ability in allopatric populations of H. magnanima.
