Abstract:
Fleas are considered as the most common and important external parasites on small mammals , which can spread a variety of viral, bacterial and rickettsial diseases to humans, such as bubonic plague and typhus.Investigation of flea fauna is an important work in natural landscape area for their biting on visitors which may raise the risk of spreading vector-borne diseases.To investigate the flea fauna and distinguish the differences among different natural landscape areas, researches were performed during autumn of 2005 in five main mountain areas: Hutiao Gorge, Haba Snow Mountain, Baishuitai Terraces, Qianhu Mountain and Red mountain.The results showed: (1) A total of 633 fleas identified as 34 species belonging to 4 genera and 19 families were collected from small rodents trapped , including 10 new recorded species (subspecies) in Shangri-La, among which Stenoponia and Stenoponia himalayana are first trapped in Yunnan province, implying that there existed abundant species of fleas in natural landscape areas in Shangri-La.(2) Both the species richness and Shannon-Wienor index of fleas increased along with the increase of altitude, which were highest in Red mountain with an altitude of 3 500-4 200 m, and lowest in Hutiao Gorge with an altitude of 1 800-1 900 m.(3) The 5 natural landscape areas were classified into two groups based on the Jaccard indexes and cluster analysis, one is Hutiao Gorge, Haba Snow Mountain and Baishuitai Terraces, another one is Qianhu Mountain and Red mountain.It is indicated that, compared with the vegetation and humidity , human disturbance may play a more important role in flea diversity of natural landscape areas . (4) Both the species richness and Shannon-Wienor index of fleas showed no relation with that of small mammal, the Spearman's rank correlation coefficients were 0.24 and 0.60, respectively.
