摘要: 在西双版纳热带地区,研究了不同时间里对叶榕传粉榕小蜂的自然种群数量变化规律,并结合控制性放蜂实验获得了实验种群的变化规律。结果表明,在不同年的同月份和同年不同月份,对叶榕传粉榕小蜂自然种群数量变化主要受气候因素的影响,低温的1月和干热的4月对传粉榕小蜂种群繁殖和生长均不利,导致种群数量最低。在人为控制情况下放蜂,不同月放蜂对后代产生雌蜂数量影响非常明显,而对雄蜂数量则无明显差异。在同月相近的不同日放蜂时,对叶榕传粉榕小蜂繁殖的后代种群数量无显著差异。

Abstract: In this paper, fig-pollinating wasp (Ceratosolen solmsi marchali) was collected from the fig Ficus hispida in the Xishuangbanna tropical area at different time to study the temporal dynamics of its population within a natural fig, and three foundresses were introduced to a single fig in different periods to know the temporal dynamics of the population size of the fig-pollinating wasp in controlled experiments. The results showed that the population sizes of the fig-pollinating wasp were varied in different years, months and days, and the numbers of female had a greater change than those of male. Some significant differences in the means of pollinators within a single fig were observed in different years and months, and the possible limiting factors were the development status of fig trees, climate, and non-pollinating fig wasp. But, there was no significant difference in the means of pollinators within a single fig in different days of a month, which was thought to be the adjustment of the vitality and lifespan of foundresses, and the figs of different spaces. This study could provide scientific basis for controlling experiments in the future.
