| Outline of Final Research Achievements |
M. Shimada, T. Kato and M. Ito conducted molecular phylogenetic analyses of Mexican bruchine seed beetles. The pattern of tree showed that beetles infesting Caesalpinoidea and Mimosoidea were located on the base and beetles infesting Papiliopoidea were at descendent positions. Seed beetles that are tolerant and utilize seeds with a poisonous substance canavanine are located in clumped clades. Y. Fujii investigated poisonous substances and effects in many legume plants extensively in Iran, Yunnan Province in China, Caucasas in Russia, and so on. M. Tuda and Y. Toquenaga carried out AMOVA to determine origin and processes of clade diversity of Callosobruchus maculatus, whose place of origin is the western Africa. Factors of genetic diversification are due to allopatric, sympatric and anthropogenic migration through trades. They analyzed statistically relative importance of the three factors of C. maculatus in each continent.
