二齿新蚤的研究现状

Current research on Neopsylla bidentatiformis

二齿新蚤广泛分布于古北界的东北亚界和中亚亚界。在我国,其主要分布于北方地区的12个省(自治区);在国外,韩国、俄罗斯和以色列等地也有该蚤分布的报道。二齿新蚤是鼠疫的重要传播媒介之一,医学意义较大。该文在收集国内外二齿新蚤相关研究文献的基础上,对其分类地位、鉴别特征、与近缘蚤种的区别、地理分布、媒介地位和生态习性等方面的研究现状进行了综述。

Neopsylla bidentatiformis is widely distributed in the northeastern region and the region of Central Asia in the Palaearctic Realm.In China,it is mainly distributed in 12 provinces or autonomous regions in the northern part,and it has also been observed in other countries such as Korea,Russia,and Israel.Neopsylla bidentatiformis is an important plague vector,which is of great medical significance.Based on relevant domestic and foreign literature,this paper reviews the taxonomic status,identification characteristics,distinction from closely related species,geographical distribution,vector role,and ecological habits of this flea.
