  • In addition to pollinator fig wasps, there are several non-pollinating fig wasps associated with monoecious Ficus sp. In order to understand how pollinator fig wasps and non-pollinating fig wasps are distributed across the same syconium, the spatial distribution of fig wasps associated with Ficus altissima and F. benjamina were compared using the pedicle lengths of galls containing each species. The results indicate that in Ficus altissima, the average pedicel length of galls containing Eupristina sp. is longer than that containing E. altissima. Average pedicel length of galls containing Sycobia sp., Micranisa ralianga and Sycoscapter sp. two did not show significant difference. The range of pedicel lengths of galls containing Sycobia sp., M. ralianga or Sycoscapter sp. two is narrower than that of galls containing E. altissima,indicating these non-pollinating fig wasps and pollinator have partially separated spatial niches. In F. benjamina, E.koningsbergeri was distributed in galls from the outer layer to inner layer, while most Walkerella sp. were found in outer layer galls, indicating E. koningsbergeri and Walkerella sp. have partially separated spatial niches.
