Abstract: Objective To investigate the composition and diversity of acaroid mite community in Huainan City. Methods Dust samples were collected from storage circumstances, human dwellings and working places. Acaroid mites were isolated, counted and identified. 30 sampling spots from each of the three environments were selected, and 2 samples, each with 10 g, were collected from each sampling spot. Results 26 species of acarid mites were identified from the three environments. These acarid mites belonged to 19 genera, 7 families. Diversity analysis showed that the average breeding density ranged from 15.35±6.13 to 31.27±8.34, the number of species ranged from 11 to 14, the values of the species richness index Rmargalef for the three circumstances raged from 1.99 to 4.35, the species diversity index (Shannon-Wiener index) ranged from 2.27 to 3.13, and Pielou index ranged from 0.95 to 0.96. Conclusion The composition and diversity of acaroid mite community in three different circumstances are different significantly, which might be relevant to temperature, humidity and human interference.
