Relationships Between Ficus erecta var beecheyana and Two Sycophilus Wasps

Abstract: Ficus erecta var.beecheyana is dioecious,and each forms either female syconia with female flowers or male ones with male and gall flowers.Both Blastophaga silverstriana and Sycoscatper sp.live in male syconia.The former is the only mutual pollinator,and can enter the syconia cavity to pollinate for the female syconia and lays eggs in most gall flowers ovaries of the male syconia.The latter can neither enter syconia not pollinate,but lays eggs into partial gall flowers ovaries from the outside of the male syconia by its long ovipositor.Results counting the wasps flying off syconia showed that:average 208.2 B.silverstriana flew off each syconium,the fly off process mainly lasted for 3 days,and 86.65% of the total fly off occurred on the second day;average 64.2 S.sp.flew off each syconium,the fly off process lasted for 4 days,and 66.51% of the total fly off occurred prior to the peak in B.silverstriana flying off;when the syconium ostiole was sealed artificially,B.silverstriana could not get into the syconium to lay eggs and only S.sp.laid eggs in gall flowers ovaries,and then average 165.6 S.sp.flew off each syconium,which was 2.5 times as many as that in the natural state.Obviously S.sp.is a vegetarian parasite of Ficus erecta var.beecheyana and competitor of pollinating wasps.In the meantime,it is also a destroyer of fig tree-pollinator mutualism system.
