Outline of Final Research Achievements

To investigate the ecological significance of dipteran pollinators at a community scale, we compared plant-pollinator communities where the proportion of dipteran pollinators differs. In general, diversity of flower colors, as well as the diversity of flower morphology, appeared to decrease as the rate of dipteran pollinators in pollinator community increase. Differences in the composition of flower color and morphology between communities are due to differences in the pollinator fauna in these communities. We also found that color preference of dipterans differed between species. Our survey further revealed that rate of conspecific pollen grains to the total pollen grains on the stigma of the dipteran pollinated plants was large as much as those of the hymenopteran pollinated plants. Our results suggest that dipteran pollinators play a significant role in maintenance of plant community.
