目的研究辽宁省蚤类区系及其分布特征。方法于2008-2015年对辽宁省境内不同自然地理区开展蚤类调查,对采集到的蚤类标本进行系统分类;运用动物地理学和自然地理学原理及方法,研究辽宁省蚤类在不同动物地理区的分布规律。结果辽宁省发现蚤类47种,隶属于6科23属。其中干草原蚤种19种、林区蚤种17种、世界广布种6种和世界局部广布种5种。在世界区系分布中与东洋界共有蚤种16种,共有成分最多,关系最密切;其次是新北界9种;与其他界别共有蚤种全部为世界广布种,关系疏远。在古北界区系分布中分布东北亚界、中亚亚界、西伯利亚亚界、欧洲亚界和地中海亚界蚤种分别为46、42、35、9和7种。因此,辽宁省与西伯利亚共有蚤种数量最多,关系最密切,其次是欧洲亚界,与地中海亚界联系较少;国内区系分布中东北区、华北区、蒙新区、青藏区、华中区、西南区和华南区分布蚤种分别为41、42、38、15、15、10和9种。结论蚤类与其他自然要素是环境不可分割的组成部分;辽宁省蚤类在各动物地理区的分布是与自然地理环境相适应的结果。
Objective To study the flora and distribution of fleas in Liaoning Province. Methods Fleas were surveyed in different natural geographical areas in Liaoning Province from 2008 to 2015 and systematically classified fleas specimens. Using the principles and methods of animal geography and physical geography, the study was conducted to investigate the effects of fleas in different animals Geographical distribution of the law. Results 47 species of fleas were found in Liaoning Province, belonging to 6 families and 23 genera. Among them, there are 19 species of fleas in the steppe, 17 species of flea species in the forest, 6 species widely distributed in the world, and 5 species widely distributed in the world. There are 16 species of flea species in the world fauna distribution, with the most common components and most closely related species; followed by 9 species in the New Beijiao; and the flea species shared with other fields are all widely distributed in the world, with a distant relationship. Distribution of the Palaearctic fossils in the distribution of Northeast Asia, Central Asia, Siberia, Europe, Europe and the Mediterranean sub-sector flea were 46,42,35,9 and 7 species. Therefore, Liaoning Province and Siberia share the largest number of flea species, the closest relationship, followed by the European sub-community, with less contact with the Mediterranean sub-sector; the domestic distribution of Northeast China, North China, Mongolia, Xinhua, Qinghai- The distribution of fleas in Southwest China and South China were 41, 42, 38, 15, 15, 10 and 9, respectively. Conclusion The fleas and other natural elements are inseparable parts of the environment. The distribution of fleas in each animal geographical area in Liaoning Province is the result of adapting to the natural geographical environment.
