摘要
本文论述薜荔榕小蜂（Ｗｉｅｂｅｓｉａｐｕｍｉｌａｅ）从薜荔（ＦｉｃｕｓＰｕｍｉｌａ）的隐头花序中出飞的节律和光因子对此节律的影响。实验结果表明了光线是小蜂建立昼夜律的决定性因素之一，清晨漫射迸花序的第一束＊光线是节律起始点，在实验条件下，小蜂的节律可以补颠倒，但是节律一旦启动则不再改变．每个隐头花序平均出飞１１９０只雌蜂，持续８ｄ，以第３天为最多，一天中的出飞高峰９：００前后．
A study on the female fig wasps(Wiebesia pumilae, Agaonidae) dispersal (flyingout) from the syconia (Ficus pumila, Moraceae) and on the ecological effects of light was conducted. The experiment shows that light was the determining factor for female of fig wasps toestablish their circadian rhythm of flying out. The time of first bundle of diffused light passingthrough the ostiole into syconia was the starting point of the rhythm. The reversal circadianrhythm experiments show that the fig wasps were able to establish a reversal circadian rhythmand that it could not be changed by reversing daily cycle once the rhythm established. The average number of female fig wasps flew out from each syconium was 1190. The flying out continued for & days. The dispersion reached the highest peak on the third day. The time atwhich most female fig wasps flew off was round 09: 00 am.
