高山榕传粉小蜂的出飞形式

Fly-out Style of Pollinating Wasps of Ficus altissima

[目的]为榕树-榕小蜂协同进化研究提供科学依据。[方法]对高山榕传粉小蜂形态结构进行观察,对其出飞通道进行比较。[结果]高山榕传粉小蜂的雄蜂既能撕咬苞口苞片开掘苞口通道,也能在果壁上开掘非苞口通道。它是小峰出飞通道的开掘者。[结论]非苞口通道的形成有利于雌蜂出飞,避免了出现通道堵塞雌蜂大量死于果内的现象,非苞口通道是榕-蜂协同进化的产物。

[Objective] The research aimed to provide scientific basis for the fig-fig wasps symbiosis system.[Method] The morphological structure of pollinating wasps for Ficus altissima were observed and the fly-out channels were compared.[Result] The pollinating male wasps for F.altissima could both bite bracts and the wall of fruit to open fly-out channel.[Conclusion] The formation of the non-bud mouth channel was more conducive to female wasps＇ flying out.Consequently it could avoid large numbers of female wasps died in fruits for channel blockage.The non-bud mouth channel on the fruit wall was the product of fig-fig wasp co-evolution.
