  • 摘要:   目的  分析鼠形动物特征和环境因子与鼠形动物寄生蚤的关系,明确影响云南剑川鼠疫疫源地野外鼠形动物寄生蚤丰盛度和丰富度的因素。  方法  选取剑川县作为采样点,分别在4个季节不同海拔梯度进行鼠形动物、寄生蚤、环境因子取样。使用跨栏模型分析环境因子(季节、生境、海拔)和鼠形动物特征指标(种类、性别、年龄、体长、体重等)与鼠形动物寄生蚤丰盛度和丰富度的关系。  结果  寄生蚤丰盛度跨栏负二项回归模型多因素分析结果显示:相比于春季,夏季、秋季、冬季的染蚤率分别降低了68%、78%、45%。与耕地相比,林地中野外鼠形动物染蚤数量减少了35%。与齐氏姬鼠相比,大绒鼠的染蚤率增加了0.41倍,中华姬鼠的染蚤率降低54%,其他种类的鼠形动物染蚤率降低了39%;中华姬鼠的染蚤数量降低60%。雌性鼠形动物染蚤率降低了25%。成年的鼠形动物染蚤数量降低了44%。体长>100 mm、耳高>13 mm的鼠形动物染蚤率分别增加了0.48、0.53倍。尾长>13 mm的鼠形动物的染蚤数量降低了49%。寄生蚤丰富度跨栏Poisson回归模型多因素分析结果显示:相比于春季,夏季、秋季、冬季的染蚤率显著降低,分别降低了68%、78%、45%。林地比耕地染蚤种类降低了47%。与齐氏姬鼠相比,大绒鼠染蚤率增加了0.41倍,中华姬鼠的染蚤率降低54%,其他鼠形动物种类染蚤率减低了39%。雌性鼠形动物染蚤率降低了25%。体长>100 mm、耳高>13 mm的鼠形动物染蚤率分别增加了0.48、0.53倍。  结论  影响寄生蚤丰盛度的因素包括季节、生境,以及鼠形动物种类、性别、年龄、体长、尾长、耳高。影响寄生蚤丰富度的因素包括季节、生境,以及鼠形动物种类、性别、体长、耳高。
