摘要
2004年在西双版纳热带地区,统计了对叶榕隐头果接受的传粉榕小蜂数量,以及所生产的种子和传粉小蜂繁殖后代数量。结果表明:对叶榕具有执行不同繁殖功能的雌果和雄果,在性别间和性别内单果接受的传粉小蜂数量都不一样,进入榕果内传粉和产卵的榕小蜂中,仅有34.71%传粉榕小蜂进入到雄果果腔内产卵繁殖;有52.06%的传粉榕小蜂进入雌果果腔内传粉,其他榕小蜂被夹死在苞片通道里。果腔内小蜂数量分布格局雌果是2.72只/果,雄果是2.08只/果。雌果单果平均生产的种子数量1891.63粒/果,雄果内平均繁育榕小蜂的数量630.21只/果。
Ficus hispida L. is dioecious, which female figs produce seeds and male figs reproduce fig wasps and pollen. We researched on the distribution of foundresses found in single female and male figs of Ficus hispida L. in Xishuangbanna tropical area. The results showed that the distribution of foundresses was different between female and male figs, and it was different among male or female figs too. When foundresses entered fig, a lot of foundresses were trapped in the ostiole, only 34.71% foundresses oviposited inside male fig, and 52.06% foundresses pollinated inside female fig. the distribution of foundresses inside cavity of fig was that female fig had 2.72 individuals and mean 2.08 foundresses inside male fig. Finally, we counted the number of seeds and fig wasps per fig. a female fig produced more seeds （ 1891.63） than a male fig reproduced fig wasps （630. 2 ）.
