Ficus superba Miq. var. japonica Miq. (Ficus, Moraceae) is a kind of deciduous and monoecious trees. From July 2011 to July 2012, thirty plants of Ficus superba Miq. var. japonica Miq. in Fuzhou were observed, collected at regular intervals. Seven fig wasp species were collected in its syconia, consisting of 6 families, 7 genera, 7 species of fig wasps. Platyscapa ishiiana was the unique pollinator, whereas the others were non-pollinating fig wasps. The non-pollinators were classified into 3 families: Pteromalidae, Eurytomidae, Eulophidae and one subfamily Epichrysomallinae. The species of fig wasps in Ficus superba have no obvious change among different months and different seasons, but the the number of different species of fig wasps varies obviously. In community structure of wasps in Ficus superba was usually dominanted by pollinating wasps. The number of non-pollinators has an obvious negative correlation with the number of pollinators. Non-pollinating wasps have negative impact for pollinating wasps.
