中文摘要：

在西双版纳地区,观察和测量了对叶榕（Ficus hispida）的结果特点、果实特征以及取食该果实的犬蝠（Cynopterus sphinx）的形态特征,并通过飞行笼实验考察了对叶榕果实提供的视觉和嗅觉信息及犬蝠取食时视觉和嗅觉的应用情况.结果表明：犬蝠利用视觉系统能成功地分辨出完整和破碎的果实,每小时访问完整果实的次数为（15.5±1.61）次,访问浆状果实的次数为（10.5±1.45）次;在访问有果实和没有果实的盒子时,每小时访问前者的次数为（37.4±7.62）次,显著高于后者（1.1±0.88）次.对叶榕果实的生物和生态学特征与犬蝠的行为学特征建立起了较好的相互适应性.

英文摘要：

Figs are very important food resource for many animals in Xishuangbanna,Southwest China,and there is mutually beneficial relation between figs and their frugivore.Observed the hung position fruits of Ficus hispida,and measured some morphological characters of fruits of F.hispida and Cynopterus sphinx,which is regular forager to their fruits.Moreover,tried to find out the relation between the information of vision and olfaction offered by fruits of F.hispida and the use of sensory system of fruit bats when they foraged the figs in flight cage.C.sphinx could successfully distinguish the whole fruit of F.hispida（15.5±1.61 times/h,n=8）from the meshed fruit（10.5±1.45 times/h,n=8）with their vision;When they visited the boxes with and without fruit,C.sphinx preferred to visit the former box（37.4±7.62 times/h,n=8）rather than to pay visits to the other box（1.1±0.88 times/h,n=8）.The results showed that F.hispida and fruit bat adapted to each other very well.
