通辽市啮齿动物体表寄生蚤多样性研究
Study on the Diversity of Ectoparasitic Fleas on Rodents in Tongliao City
摘要
Abstract
To investigate the diversity characteristics of ectoparasitic fleas on rodents in Tongliao City,Inner Mon-golia,a survey was conducted from April to October 2023.Twelve representative sampling sites were selected in Jarud Banner,Horchin Left Wing Middle Banner,and Horchin District within Tongliao City,covering three main habitats types:grassland,farmland,and sandy land.The results showed that a total of 1 247 rodents belonging to 8 species were captured,and 2 856 parasitic fleas belonging to 12 species,9 genera,and 4 families were collected.Among them,Citel-lophilus tesquorum and Neopsylla bidentatiformis were the dominant species,accounting for 31.2%and 24.7%respec-tively.The overall Shannon-Wiener diversity index was 2.14,and the Simpson dominance index was 0.78.Among the different habitats,grassland exhibited the highest diversity(H'=2.31),while sandy land showed the lowest(H'=1.67).The parasitic flea communities demonstrated significant seasonal dynamics,with the peak occurrence period from May to July.Meriones unguiculatus and Spermophilus dauricus were the primary hosts,jointly harboring 78.3%of the para-sitic fleas.Vegetation coverage,soil moisture,and host density were the main environmental factors influencing the di-versity of parasitic fleas.关键词
