菩提树传粉小蜂的形态学及其性比特征研究

he pollinator wasps of F. religiosa, Platyscapa quadraticeps (Mayr) whose morphological characters have been described, was observed in Fuzhou area for the first time, but did not find its non-pollinating wasps. The sex ratio of pollinating fig wasps was 0.10±0.06. Compared with other small fruit type monoecious Ficus trees, the sex ratio showed extremely female-biased sex ratio. This may be attribute to the short time of foundress wasps distribution, resulting in enough figs but insufficient female wasps in generall, especially insufficient female wasps in per fig, which further resulting in high intense local mate competition.
