title: [Investigation on species and community ecology of cheyletoid mites breeding in the stored traditional Chinese medicinal materials].
abstract: OBJECTIVE
  To investigate the species of Cheyletoid mites breeding status in the stored traditional Chinese medicinal materials and the relationship between its community and habitats.
  
  
  METHODS
  A total of 60 samples of the traditional Chinese medicinal materials were collected from Huainan, Wuhu and Xuancheng in China. The mites were isolated with shakesieve shock, directicopy, Tullgren funnel, waternacopy and redricopy, and identified and counted under the light microscope.
  
  
  RESULTS
  Cheyletoid mites were represented in 48 of the 60 samples, and the breeding rate accounted for as high as 80.0% (48/60). Totally, 6 species of Cheyletoid mites were identified, which belonged to Cheyletus, Acaropsis, Cheletomorpha, Eucheyletic and Pseudocheyles genera under the family of Cheyletidae. In the three investigated areas, the average breeding density of Cheyletoid mites was 109.75 heads/g, and average richness index was 1.54. The index of species diversity was 2.55 and the number of evenness was 0.95.
  
  
  CONCLUSIONS
  This result entails positive prevention and control of the mite breeding in storage and processing of herbal materials.
