无花果和它们的传粉黄蜂是专性互利共生的一个典型例子。此外，无花果被一套非互惠的黄蜂寄生，其基本生态基本上没有描述。榕小蜂亚科（Epichrysomallinae）榕小蜂属（Sycophilomorpha）榕小蜂是一种以胚珠为寄主的小蜂，该属仅有1个已知种。在西双版纳发现一种寄生于高山榕上的未描述的管蚜蝇属昆虫。观察到黄蜂在仍然隐藏在总苞下的小的未成熟的无花果上产卵。一个Sycophilomorpha黄蜂产卵超过1无花果，花了很长的时间，奠定了一个单一的无花果大的离合器。黄蜂自然发生在所有7个采样的树木，但黄蜂的发生是显着不同的树木，作物和月份。这些黄蜂能够防止未授粉的无花果被流产，它们的后代能够在没有传粉黄蜂或种子的无花果中发育。榕小蜂对榕-榕小蜂共生关系有不利影响。存在Sycophilomorpha黄蜂的无花果产生的种子、传粉者和骗子显着减少。然而，在无花果中的Sycophilomorpha的丰度仅显着负相关传粉者生产，而不是种子或骗子生产。我们的研究说明了一个以前未知的无花果小蜂生态位，并扩大了我们的理解，可以影响无花果-无花果小蜂的相互作用的因素。
SUMMARY Figs and their pollinating wasps are a classic example of an obligate mutualism. In addition, figs are parasitized by a suite of non-mutualistic wasps whose basic ecology is largely undescribed. Sycophilomorpha (subfamily Epichrysomallinae) fig wasps are ovule gallers and the genus contains only 1 described species. An undescribed Sycophilomorpha species parasitized Ficus altissima at Xishuangbana, Southwestern China. The wasp was observed ovipositing on the tiny immature figs that were still concealed beneath the involucral bracts. A Sycophilomorpha wasp oviposited on more than 1 fig and spent long time-periods to lay large clutches on a single fig. The wasps naturally occurred on all 7 sampled trees, but the occurrence of wasps was significantly different among trees, crops and months. These wasps were able to prevent unpollinated figs from being aborted, and their offspring were able to develop in the figs that otherwise had no pollinator wasps or seeds. The Sycophilomorpha wasp had a detrimental effect on the fig–fig wasp mutualism. Figs in which Sycophilomorpha wasps were present, produced significantly fewer seeds, pollinators and cheaters. However, the abundance of Sycophilomorpha in a fig was only significantly negatively correlated with pollinator production and not seed or cheater production. Our study illustrates a previously unknown fig wasp niche and expands our understanding of factors that can affect the fig–fig wasp interaction.
