Abstract: Objective To understand the species and distribution of sucking lice on small mammals in Dali,Yunnan Province,China.Methods The small mammals are captured by mouse traps.The sucking lice on the body surface of small mammals were all collected.Every individual of the sucking lice was made into slide in a conventional way and then identified.Results 636 individuals of 22 species of small mammals were captured and 8 051 individuals of sucking lice from the hosts were collected.The collected lice are identified as 14 species of five genera of four families.There are only one or two species of lice on most small mammals body surface and few hosts have three or four louse species.The louse communities on small mammal hosts are quite simple with lower species richness and diversity and with a high dominance index.Conclusion Small mammals usually have fewer species(one or two species) of sucking lice on their body surface with less species diversity.Most species of sucking lice usually have a high host specificity.
