摘　　要：目的记述两种新蚤的地理分布与宿主关系,丰富生态学数据。方法根据宁夏不同的地理景观和海拔高度,采用媒介昆虫学调查方法,结合历年鼠疫疫源调查及监测结果进行研究。结果二齿新蚤Neopsylla bidentatiformis Wagner,1883,分布在宁夏古北界蒙新区东部草原亚区的草原景观区,海拔1 010~1 480 m,其宿主简单、数量较少;红羊新蚤Neopsylla hongyangensis Li,Bai et Chen,1986,主要分布在古北界华北区黄土高原亚区的森林景观区,海拔1 660~3 200 m,其宿主广泛、数量较多。结论两种新蚤地理分布不同,二者受海拔高度的影响,而形成垂直的区别。Objective To record geographical distribution of two kinds of Neopsylla and relationship with their hosts, to enrich ecological data. Methods According to the different geographical landscape and altitude in Ningxia, vector entomology investigation was carried out by combining with historical investigation and surveillance results of plague foci. Results Neopsylla bidentatiformis Wagner,1883 distributed in Mongolian steppe landscape district, East New District, subdistrict of Ningxia grassland in the Palaearctic, at elevations between 1 010-1 480 m, with simple and less quantity of hosts. While Neopsylla hongyangensis Li, Bai et Chen, 1986 mainly distributed in forest landscape area of the Palaearctic region in North China Loess Plateau subregion, at an elevation between 1 660-3 200 m, with widespread and large number of hosts. Conclusions The geographical distribution of the two species of Neopsylla is different, and affected with the change of altitude to form vertical difference.
