摘　　要：对福州市区27株笔管榕的雄花期榕果进行定时定点采集、观察与鉴定,在802个榕果内采集到小蜂标本48 990只,隶属于小蜂总科中的5个科(亚科)7个属的7个种,其中榕小蜂科的Platyscapa ishi-iana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.单个榕果中的榕小蜂通常有1～3种,最多5种,传粉小蜂在榕果中普遍存在,数量由几十只到上百只不等,约占82.75%.非传粉小蜂中Philotrypesis sp.、Acophila mikii、Otitesella ako所占的比例较高,分别为5.89%,5.61%,3.17%.Sycophila sp.、Sycobiomorpha sp.所占比例较低,分别为1.94%,0.65%,这5种小蜂全年几乎各个月份都可采集到,属常见种.Aprostocetus sp.全年仅收集到3只,为偶见种.对福州笔管榕榕果中小蜂的形态特征进行了描述,并编写了分种检索表.In order to study the wasp species of F. superpa Miq. var. japonica Miq. in Fuzhou, male-phase syconia from 27 fig trees in Fuzhou urban area were collected, observed and identified at regular intervals. About 48 990 specimens were collected from 802 syconia, consisting of 5 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. In general, there were 1 - 3 wasp species in a single syconium, a maximum of 5. Pollinating fig wasps existed widely in the syconia in numbers by the dozens to hundreds of range, accounting for about 82. 75%. Philotrypesis sp. , Acophila mikii, Otitesella ako have a higher proportion of the total, were 5.89%, 5.61% and 3.17% respectively. Sycophila sp. , Sycobiomorpha sp. have a lower proportion of the total, were 1.94%, 0. 65% respective. These kinds of fig wasps were common species, can be collected almost all year round. Aprostocetus sp. were rarely found in syconia, since we collected only three samples throughout the year. Morphological characteristics of wasp in syconia of F. superpa Miq. var. japonica Miq. in Fuzhou were described, and the classification key of fig wasp species was prepared.
