对叶榕传粉榕小蜂在时间格局上的种群动态

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。

Temporal dynamics of Ceratosolen solmsi marchali population on Ficus hispida

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.
