The first and the second generations of female fig wasps ( Wiebesia pumilae (Hill) Wieb., Agaonidae) start flying out of the gall flowers in the gall syconia at the time when the male flowers are in bloom. Such synchronism ensures that the female flowers can be pollinated and bear fruit, and provides good conditions for the wasps to complete the life cycle.展开更多

The best conditions to extract total flavonoides are: 1∶40 ethanol solution of 70%, at 70～75℃ for four hours. Under the same condition, more total flavonoides can be extracted from leaves than receptacle of inflorescence. The effects of different reagents on total flavonoid extracting are also reported.展开更多
