The widespread fig species usually
possessed a large number of individuals of
pollinators. However, the number varied in
each season [18, our observation]. There were
many syconia of some figs without pollination
e.g. F. ischnopoda and F. subincisa. Almost figs
dropped in a few weeks. Perhaps there was
small population of pollinators in nature. In
dioecious fig tree, male tree bear fig wasp
offspring in its syconium. If there is less male
tree population in the area, fig wasps cannot
survive without syconium. Thus the status
of synchronous crops both within tree and
among tree can solve this problem. Fig wasps
can immerge the new receptive fig in the same
tree or other tree. In the study, synchronous
crops was usually occur in dioecious fig except
a big syconium monoecious fig as F. rasemosa.
It bears lots of syconium and fig wasps,
sometime the new generation pollinators
immerge to the same tree again.
