| Outline of Final Research Achievements |
Focusing on evolution of phytophagous insects associated with the most basal plant group, Bryophyte, we explored biodiversity, morphology, ecology, host-specificity and phylogeny of Micropterigidae and Spaniinae (Rhagionidae). In addition, we discovered the first example of insect gall on bryophytes from Peru. The gall formed on Monoclea thallus was unique in that the gall was neither ornamented nor sclerotized unlike the galls on seed plants. Together with these research, we created a preliminary database of host plants of Japanese leaf-miners. As for mutual plant-herbibore interactions, obligate pollination mutualism has been konwn only from Old World. We discovered an obligate pollination mutualism of Phyllanthaceae from the Neotropics. By compiling the knowledges on the mutualism so far accumulated, we published a treatise entitled "Obligate pollination mutualism".
