Vollenhovia emeryi chosenica (Wheeler) (Hymenoptera: Myrmicinae) is an ant species frequently found in forests. In nature, two phenotypically distinct forms are found e.g. long winged and short winged. Unlike other hymenopteran insects, the ant is unique in its mode of reproduction. In this species, queens are clonally reproduced from unfertilized eggs. On the other hand, workers develop from fertilized eggs. Strikingly, haploid males are reproduced from fertilized eggs after destroying the maternal half of the genome e.g. maternal genome loss (MGL) consequently only with the paternal half of the genome. We collected the ant colonies nationwide in 2011. In this study, we demonstrate that the ant is infected with Wolbachia, the bacterial reproductive manipulator in various insects. Interestingly, only the long winged morphs seem to be infected. Furthermore, most colonies are mulitple-infected except two colonies collected from Chuncheon and Mt. Deogyu. We will discuss potential interactions among the Wolbachia infection polymorphism and wing morphology, and evolution of clonal reproduction and MGL.
