摘　　要：[目的]研究大蹄蝠(Hipposideros armiger)的食物组成及其对森林虫害发生的影响。[方法]采用粪便分析和直接观察法分析大蹄蝠捕食食物的组成,并采用样地调查法研究森林虫害发生情况。[结果]鞘翅目(31.59%～37.21%)和鳞翅目(15.38%～22.87%)在大蹄蝠食物组成中所占比例较大,是大蹄蝠的主要食物组成部分;随着大蹄蝠种群数量的锐减,大蹄蝠活动半径区域内森林的虫害正呈逐年上升趋势,在0～4 km半径区域内森林虫害平均发生率由2006年的14.25%上升到2010年的26.93%。[结论]为大蹄蝠的保护工作提供了理论依据。[ Objective I To study the food composition of Hipposideros armiger and its influence on the occurrence of forest pests. [ Method ] The food composition was analyzed by fecal analysis and intuitive method, and the occurrence of forest pests was studied by sample investigation meth- od. [ Result] Coleoptera （31.59% - 37.21% ） and Lepidoptera （ 15.38% - 22.87% ） accounted for larger proportions in the food composition of Hipposideros armiger. Along with the declining population of Hipposideros armiger, the forest pests were increasing year by year in Hipposideros armiger activity radius areas, and average occurrence rate of forest pests rose from 14.25% in 2006 to 26.93% in 2010 within 0 -4 km radius. [ Conclusion] The study provides theoretical basis for the protection of Hipposideros armiger.
