摘　　要：薜荔榕小蜂Blastophagapumilae是薜荔的传粉昆虫 ,栖息于薜荔隐头花序中 ,在其生物学行为中以钻入花序产卵或传粉最为关键。研究表明 :薜荔榕小蜂钻入花序平均费时 6 9 48min ,标准差 13 2 6min ;伤残程度很高并能在伤残的情况下完成产卵或传粉 ;卵的尾丝能起标识作用避免重复产卵 ;进入雌花序的小蜂具逃离花序的行为但不能实现 ;1只小蜂平均产5 2 8个卵或为 10 72 4朵雌花授粉。As an insect pollinator of Ficus pumila, Blastophaga pumilae lives in the syconia of this fig. Female wasps of B. pumilae enter syconia of this fig either to oviposit or pollinate. The average time for B. pumilae to enter syconia was 69 .48 min (SD 13 .26 min). Although the injury rate of the wasps that enter syconia was quite high, they can nonetheless complete egg-laying or pollination. The tail fibers of eggs cause females to avoid laying eggs again in the same ovary. Once the wasps have entered female syconia, they try but are unable to escape. Typically, one female wasp can lay 528 eggs or pollinate 1 072 .4 flowers.
