Study on the Food Composition of Great Leaf-nosed Bats (Hipposideros armiger) and Its Impact on the Occurrence of Forest Pests
[Objective] 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 method. [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.
