摘要:本研究通过全年对福州地区的 30 株笔管榕进行的定时、定点、定株观察与采集,结
果表明笔管榕榕果内有 7 种小蜂,隶属于小蜂总科中的 6 个科(亚科)7 个属,其中榕小蜂
科的 Platyscapa ishiiana 为传粉小蜂,其余 6 种为非传粉小蜂,分别属于金小蜂科、广肩小
蜂科、姬小蜂科及隐针榕小蜂亚科。笔管榕榕果内的榕小蜂种类在不同月份、不同季节没有
明显变化,但不同种类榕小蜂的数量变化明显。在笔管榕榕小蜂群落结构中通常是传粉小蜂
占优势,非传粉小蜂的数量和传粉小蜂总数呈极显著负相关。非传粉小蜂对传粉小蜂的负面
影响。

Abstract: 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 obv
