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.
