No Wolbachia infection was detected in Drosophila elegans collected from the wild in the Ryukyu Islands, Japan

Flower breeding, tropical and subtropical Drosophila elegans is distributed in the Ryukyu Islands and Taiwan (black morph) and in southern China, Philippines, Indonesia, and New Guinea (brown morph). Although reproductive and behavioral manipulations by Wolbachia are reported in many insect taxa, Wolbachia infection in D. elegans is unclear. There is only a report of no Wolbachia detected in a laboratory strain of brown morph. This PCR diagnosis study revealed no Wolbachia infection in D. elegans males collected from the wild in the Ryukyu Islands. We concluded that D. elegans black morph in the Ryukyu Islands is not infected with Wolbachia .
