Biological interactions include mutualistic relationships that have a positive effect on the fitness of each other, and parasitic relationships that one species has a negative effect on the fitness of the other species. Furthermore, organisms can be classified into generalists who can relate to various organisms and specialists who can only relate to specific organisms. Plants have evolved various defense functions against feeding damage by herbivores, but specialist herbivores can adapt to their defense functions and feed on the plants. In this thesis, I investigated to clarify the reproductive strategies of the perennial herbaceous plant Sanguisorba tenuifolia var. alba against herbivory of the specialist floral herbivore Phengaris teleius, as well as the variation of defense functions against herbivory among years and among populations. Finally, I also examined the existence of positive contribution of P. teleius such as pollinator besides the floral herbivore.
