| 中文摘要: |
| 棕果蝠(Rousettusleschenaulti)在云南西双版纳地区是比较常见的果蝠。本文研究了棕果蝠对当地经济作物龙眼(Dimocarpuslongan)的取食模式和取食时间规律,并在实验室条件下研究了其对龙眼的整夜进食量。野外观察发现:棕果蝠叼取龙眼后不在母树上停留,而是携带龙眼到其他进食地点进食。棕果蝠在19:30～5:30时有3个取食高峰期,分别是在20:30～21:00时、22:00～22:30时和1:00～1:30时之间。此外,室内笼养实验结果表明,棕果蝠对龙眼的取食个数因体重不同而有差异,个数在6～20之间,实际进食量相当于其体重的1.0～1.8倍。 |

| Rousettus leschenaulti is a common fruit-eating bat in Xishuangbanna,Southwest China,its feeding behavior was observed in the field and its food intake on fruit of Dimocarpus longan was estimated in the laboratory. R. leschenaultia usually caught fruits from one tree and took the food to another species of trees to consume them in the study area. During the period of the research,we did not observe the bat consuming the fruit of D. longan in where they got them. There were three foraging peaks at 20:30 - 21:00,22:00 - 22:30 and 1:00 - 1:30 in the night from 19:30 to 5:30 next morning. . We fed the 10 bats with the fruits of D. longan and found that each bat consumed 6 to 20 fruits of D. longan depending on their body weight. The quantity of food took by each bat in one night was as weight as 1 - 1. 8 times of its body mass. |
