摘要: 本文对粗叶榕(Ficus hirta Vahl)的外部形态、花序结构以及寄主和传粉者的繁殖特性作了比较详细的观察和研究, 讨论了它们互惠共生关系的一些基本特征。它的专性传粉者是榕小蜂科(Agaonidae)榕小蜂亚科(Agaoninae)的爪哇榕小蜂(Blastophaga javana Mayr)。观察发现粗叶榕还存在两种非授粉小蜂Sycoscapter sp.和Philotrypesis sp.,它们在榕果外产卵。

Abstract: Morphology and syconium structure of Ficus hirta Vahl, the reproductive traints of host and its symbiotic wasps, and some basic features of their mutualism system, are discussed. In gall figs, there are 3 species of fig wasps (Chalcidoidea: Hymenoptera), one of which is a legitimate pollinator, Blastophaga javana of Agaoninae, the other two are nonpollinators, Sycoscapter sp. and Philotrypesis sp. (Sycoryctinae) which oviposit outside syconium.
