Our purpose is to reveal the detailed postglacial colonizing routes of broad-leaved evergreen forests from the refugia in the Quaternary. In this study, to obtain results, we used intraspecific variations in mitochondrial DNA (mtDNA) of phytophagous animals for the phylogeographic study of their host plants. The mtDNA of the phytophagous insect Curculio hilgendorfi had a greater amount of intraspecific variation than that of the cpDNA of the plants growing in the same Castanopsis-dominant forests. Minimum spanning network of the mtDNA haplotypes showed that haplotypes of primordial origin were geographically quite widespread; whereas those of recent origin were restricted to one or a few localities. Therefore, the phylogenetic information among the mtDNA haplotypes will be useful for the phylogeographic study of Cu. hilgendorfi. Such patterns were not seen in plant cpDNA haplotypes. The host-parasite relationship between Castanopsis and Curculio hilgendorfi also proved to be very tight in this study. If the phylogeographic congruency between phytophagous insects and their host plants could be demonstrated, information about intraspecific mtDNA variation in the phytophagous insect Cu. hilgendorfi would be very useful for the phylogeographic study of Castanopsis type broad-leaved evergreen forests in Japan.
