摘　　要：目的研究板齿鼠的食物组成,分析食物结构的季节和年际间发生规律,为制定科学的防治对策及可持续治理技术方案奠定理论基础。方法采用野外观察法和胃内容物分析法。结果板齿鼠胃内纤维类食物占(68.68±5.17)%,淀粉类和动物性食物分别占(23.06±4.32)%和(8.26±1.43)%;不同年龄、不同性别、不同季节和年际间鼠胃内容物的成分差异有统计学意义(P<0.01);雌鼠淀粉类和动物性食物的检出率显著高于雄鼠,幼鼠淀粉类和纤维类食物的检出率高于亚成体鼠和成体鼠,但差异无统计学意义(P>0.05),而成年鼠动物性食物的比例明显高于亚成体和幼体,差异有统计学意义(P<0.01);夏秋季淀粉类和动物性食物的检出率显著高于其他季节,而纤维类食物的检出率冬春季明显多于夏秋季。结论自然状态下板齿鼠主要取食纤维类食物,也取食淀粉类和动物性食物,食物构成的差异性与种群繁殖状况、作物生育期和栖息地的植被类型有密切关系。Objective ;Fo analyze the dietary composition of Bandicota indica to unearth the seasonal and annual patterns of the food structure, providing theoretical foundation for the development of scientific control countermeasures and sustainable management. Methods The contents of rat stomachs were analyzed in conjunction with field observation. Results Fibers accounted for （68.68±5.17）% in the gastric contents of the rats, while starch food （23.06±4.32）% and animal food （8.26 ± 1.43）%, respectively. Significant differences were found in the gastric contents of subjects of different age, sex and in different seasons and years （P〈O.01）. The proportion of starch and animal food in females was significantly greater than that in males. No significant differences were found in starch and fiber food consumed by the juvenile versus that by the sub-adults and adults, though the juvenile had higher intake of such kind of food （P〉0.05）. However, the proportion of animal food consumption in adults was significantly higher than that in sub- adults and juvenile （P〈0.01）. Considerable seasonal disparity in the food structure, characterized by higher amount of starch and animal food in summer and autumn and higher amount of fiber food in winter and spring, was also shown in B. indica. Conclusion B. indica were mainly fed on fiber food, as well as starch and animal food, under natural conditions. Diversity of food structure was associated with the reproduction and population growth, growth season of crops and vegetation types of the habitat.
