[Research on the area distribution and host selection of Leptotrombidium scutellare in 19 counties of Yunnan Province].

In order to investigate the area distribution and host selection of Leptotrombidium scutellare in Yunnan Province, a field survey was carried out during 2001 to 2009, based on different geographic location, topography, climate and ecological characteristics. A total of 16 491 L. scutellare were captured from the body surface of 9 838 small mammal hosts of 7 families, 18 genera, and 30 species in 4 orders, accounted for 17.

[Preliminary analysis of chigger mite community on Eothenomys miletus in 19 counties of Yunnan province].

Eothenomys miletus were captured in 19 counties of Yunnan Province. The distribution of species-abundance and the species-plots relationship between E. miletus and chigger mites were analyzed by using ecological statistic method.

[Preliminary survey on the distribution of Leptotrombidium deliense in some areas of Yunnan province].

Objective: To investigate the distribution of Leptotrombidium deliense among different small mammal hosts in some areas of Yunnan province.

Methods: A field survey was carried out in some counties of Yunnan province and the small mammal hosts were captured, using mouse cages and traps with baits. Chigger mites on the surface of two auricles were scraped off by a bistoury, and then preserved in 70% ethanol.

Host selection and niche differentiation in sucking lice (Insecta: Anoplura) among small mammals in southwestern China.

Understanding factors that shape host selection has been a classic issue in ecology, evolutionary biology, and epidemiological investigation. During the survey from 2000 to 2009, a total of 11,216 individuals of small mammals were captured from Yunnan Province in southwestern China. The captured small mammalian hosts belong to five orders, ten families, 35 genera, and 65 species and from their body surface, 38,885 individuals of ectoparasitic sucking lice were collected, which represent five families, seven genera, and 31 species.
