Diversity of flower-visiting beetles associated with primitive plants and its evolution of host utilization and exploration of useful pollinators

首次对苏铁、棕榈、厚朴等原始植物的访花甲虫进行了广泛的调查，并对其有用的传粉者作了如下阐述。在东半球和新大陆的热带地区，象甲(Molytinae)和钟象(Oxycoryninae)分别是苏铁的有效传粉者。针叶象甲和卷叶象甲分别为热带亚洲和世界其他地区的棕榈树所致。Ochyromerine和Ellescine Curculouid象甲分别为北半球包括热带亚洲和南半球的厚朴类象甲。它们中的大多数是未被描述的物种或代表新属的事实表明，尽管有椰子和糖棕榈树等有用的植物，但它们是如何被长期未被开发和认识到它们的存在的。

Flower-visiting beetles of primitive plants such as cycads, palms and magnollids were surveyed extensively for the first time, and their useful pollinators were elucidated as follows. Curculionid (Molytinae) and belid (Oxycoryninae) weevils are useful pollinators for cycads in the Old and New World tropics, respectively. Acalyptine and Derelomine curculionid weevils are for palms in the tropical Asia and other parts of the world, respectively. Ochyromerine and Ellescine curculionid weevils are for magnollids in Northern Hemisphere including tropical Asia and Southern Hemisphere, respectively. The fact that most of them were undescribed species or representing new genera indicates how they have been unexplored and unrecognized their existence for long in spite of the useful plants such as coconut and sugar palms.
