摘要：
本文运用动物地理学方法, 研究蚤类在宁夏不同动物地理区划的分布规律.对文献中动物、昆虫区系调查资料及现有蚤类标本统计分析整理, 结果显示, 宁夏地区共发现蚤类9科39属116种 (亚种), 其数量约占我国蚤类的1/6,其中古北界的蚤类89种 (亚种), 占76.72%; 东洋界3种, 占2.59%; 两界兼有17种 (亚种), 占14.66%; 广布种7种, 占6.03%.古北界中亚亚界蒙新区西部荒漠亚区贺兰山地省,记录4科13属14种 (亚种), 占宁夏蚤种的12.07% (14/116), 其中古北界的种类占78.58%, 东洋界7.14%, 两界兼有种7.14%, 广布种7.14%.东部草原亚区宁中间山盆地缓坡丘陵及北部平原省, 记录7科24属52种 (亚种), 占宁夏蚤种的44.83% (52/116), 其中古北界的种类占78.52%, 东洋界1.92%,两界兼有种11.54%, 广布种7.69%.古北界东北亚界华北区黄土高原亚区宁南黄土丘陵省, 记录7科26属53种 (亚种), 占宁夏蚤种的45.69% (53/116), 其中古北界的种类占77.36%, 两界兼有种16.98%,广布种5.66%.六盘山地省, 记录8科29属59种 (亚种), 占宁夏蚤种的50.86% (59/116), 其中古北界的种类占79.66%,东洋界1.69%, 两界兼有种13.56%, 广布种5.09%.%To study the fauna and distribution of fleas in Ningxia Hui Autonomous Region. Zoogeographical method was employed to study the flea distribution in Ningxia zoogeographic division, and the previous investigation information of natural focus diseases such as plague and zoonosis-borne diseases, as well as the data of animal and insect fauna and existing specimens of fleas, were statistically analyzed and collated. A total of 116 species and subspecies of fleas were found belonging to 39 genera and 9 families, and accounted for about 1/6 of the fleas species in China. Of which 89 species and subspecies (76.72%) were found in palaearctic realm, 3 (2.59) in oriental realm, 17 species (14.66) in the both realms and 7 species ( 6.03%) were widespread species. Four families, 13 genera and 14 species and subspecies of fleas distributed in the Helan mountain province of Western desert subregion of Mongolia-Xinjiang region of Central asia subrealm of Palaearctic realm, accounted for 12.07% ( 14/116) of Ningxia flea species, including 78.58% Palaearctic species, 7.14% Oriental species, 7.14% the both realms species and 7.14% widely distributed species. Seven families, 24 genera and 52 species and subspecies of fleas distributed in the Ningxia middle mountain basin gentle slope hillock and the northern plains province of eastern prairie subregion, accounted for 44.83% (52/116) of Ningxia flea species, among them 78.52% were Palaearctic species, 1.92% were Oriental species, 11.54% the both realms species and 7.69% widely distributed species. Seven families, 26 genera, 53 species and subspecies of fleas distributed in the Southern Ningxia loess hillock province of northeast subrealm of Palaearctic realm, accounted for 45.69% (53/116) of Ningxia flea species, and more than 77.36% were Palaearctic species, 16.98% the both realms species and 5.66% widely distributed species. Eight families, 29 genera 59 species and subspecies of fleas distributed in the Liupanshan province, accounted for 50.86% (59/116) of Ningxia flea species, among them 79.66% were Palaearctic species, 1.69% Oriental species, 13.56% the both realms species and 5.09% widely distributed species. Fleas are distributed in various zoogeographic regions of Ningxia Hui Autonomous Region, and the relationship between hosts and fleas is a result of long-term adaptation and evolution in nature.
