Objective: To investigate the ecological niches of sucking lice (Phthiraptera: Anoplura) on the body surface of small mammal hosts and the co-evolutionary relationship between lice and mammal hosts in Yunnan Province.

Method: Thirty species of small mammals were captured and used as 30 resource sequences. The distribution and composition of the dominant 22 species of sucking lice on the body surface of the 30 species small mammal hosts were analyzed as the utilization proportion for each resource sequence. The niche breadth and proportional similarity were measured. SPSS 13.0 statistical software was used for analyzing the niche overlap matrix of sucking lice by hierarchical clustering analysis, and a dendrogram was made.

Results: The niche breadth was narrow for most species of sucking louse. Among the detected species, Hoplopleura pacifica showed the widest niche breadth, but only 0.1536. Indices of niche proportional similarity of most sucking lice were relatively small from 0.0005 to 0.4695. The 22 species of sucking lice were classified into 16 niche overlap groups, by lambda = 5.5, through a hierarchical clustering analysis for the niche overlaps, and the clustering process of most sucking lice was late.

Conclusion: The sucking lice have a high specificity for hosts, of which different species show an apparent niche divergence on host selection. The results reveal a high coevolution between sucking lice and the mammal hosts.

Brief summary: Sucking lice are exclusively hematophagous ectoparasites of eutherian mammals, and are world-wide distribution. The results show that 96 species belonged to 22 genera, 11 families of Anoplura have been described in China, accounting for 64.71 % , 45.83%, 17.14% of known sucking lice secies, general and families in the world, respectively.

There are 27 endemic sucking lice species in China.Each family (genus) of sucking louse has the corresponding host animal and parasites on the specific family (genus) host animal. The results indicate that the fact there is a high host specificity of sucking lice and also represent the ecology phenomenon of coevolutionary relationship between sucking lice and their mammal hosts.

The paper provided a list of names of the host animals and sucking lice in China and a comparison of known genus of the lice in China with the rest of the world.
