    北海道大学->首都大学東京->北海道大学Extent of genetic differentiation between two sympatric ladybird beetles, Henosepilachna niponica and H. yasutomii, which are thought to be reproductively isolated from each other by their host preferences alone, was assessed using microsatellite markers established in this project. The analyzed data revealed that the genetic variation both within and between species were very low. These results suggest that the speciation of two species would have occurred so recently with short time that there is little genetic differentiation between them, except for a number of genes associated with the...

    首都大学東京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 kno...

    北海道大学Effects of host change on the reproductive isolation of phytophagous specialists were studied using phytophagous ladybird beetles and leaf beetles. Host shift has resulted in nearly complete reproductive isolation between two pairs of specialist species/populations by ecological isolation. In addition, in temperate regions, phenological differences between two potential host plants affected oviposition and/or diapause schedules of phytophages. Examples were also given for parallel host shift, rapid host shift, beetle plasticity in ability to utilize various potential host plants, and effect...
