| Research Abstract |
This project aims to develop a new cooperative study on the evolutionary biology of drosophilids in the Asian region. During the term of this project, field surveys at many nature reserves in southeastern China, Indonesia, Vietnam and Malaysia were performed. By studying phylogenetic relationships of some Asian drosophilid groups, it was revealed that the largest genus Drosophila in the family Drosophilidae and its subgenus Sophophora including Drosophila melanogaster are paraphyletic, suggesting the necessity of revising the classification system of the whole family. Moreover, many new knowledge for speciation process of several closely related species groups of Drosophila were obtained from taxonomic, cytogenetic, population genetic and molecular phylogenetic studies.
