头细蛾属昆虫协同进化模式与形成机制的研究概况

Evolutionary diversity of symbiosis in obligate pollination mutualisms promote species richness strenuously. Since the mutualism between Epicephala and Phyllanthaceae came under observation, researches on co-evolutionary patterns and mechanisms guided the development direction of this field. More and more exceptions of the one-to-one rule were provided in recent years. These different categories of patterns extend the thinking about symbiotic diversity greatly. In this paper, we review on the currently known symbiosis models of mutualisms between Epicephala and Phyllanthaceae and do analysis and discussion directing at some special ones.
