【摘要】：目的分析云南省居民区室内蚤类及其宿主动物的关系。方法 2009-2013年,在云南省5个不同动物地理小区内43个县(市、区)的山地及坝区居民区室内,采用笼夜法捕获鼠形动物,并收集体表寄生蚤。利用Levins生态位宽度和Shannon-Wiener多样性指数公式,测定动物地理小区蚤类的宿主生态位和蚤类及其宿主的多样性指数。结果共采获蚤类5科11属13种1 925匹,宿主动物3目5科10属14种1 582只。在13种蚤中,绒鼠怪蚤、野韧棒蚤、猫栉首蚤、不等单蚤和缓慢细蚤的寄主生态位宽度较高,分别为0.252 5、0.252 5、0.252 3、0.214 5和0.202 3。14种宿主动物中,寄生蚤多样性指数以大足鼠最高(1.517 9),其次为小家鼠(1.352 2)和褐家鼠(1.116 6)。各动物地理小区居民区室内蚤类多样性为:Ⅰ.横断山中部小区Ⅴ.滇南山地小区Ⅲ.滇东高原小区Ⅱ.横断山南部小区Ⅳ.滇西高原小区;宿主动物多样性指数为ⅠⅢⅤⅡⅣ。结论蚤类多样性与宿主动物多样性、丰富度和密度的关系不密切;蚤类的寄主生态位宽度能一定程度反映蚤类成虫对宿主动物选择的特异性关系。
[Abstract]:Objective to analyze the relationship between indoor fleas and their host animals in residential areas of Yunnan Province. Methods from 2009 to 2013, rodent animals were captured and parasitic fleas were collected by cage night method in mountainous and dam residential areas of 43 counties (cities, districts) in 5 different zoogeographic areas of Yunnan Province. Using Levins niche width and Shannon-Wiener diversity index formula, the host niche and diversity index of fleas and their hosts in zoogeographic plots were determined. Results A total of 1 925 fleas belonging to 11 genera and 5 families were collected, and 1 582 species and 14 species belonging to 10 genera and 3 orders of host animals were collected. Among the 13 species of fleas, the host niche widths of the three species were higher, which were 0.252 50.2520.2520.2520.2125, and 0.202 3.14 host animals, respectively, of the 13 species of fleas, Ctenopsylla tenuifolia, Ctenophora tenuiformis, Diopsylla unequalis and Daphnia slowus, respectively. The diversity index of parasitic fleas was the highest (1.517 9), followed by mice (1.352 2) and Rattus norvegicus (1.116 6). The diversity of indoor fleas in various zoogeographic areas is as follows: 鈪，
