Abstract: Objective To investigate habitat and diversity of storage mites and dust mites community from 3 different motors in Anhui province. Methods Collection, isolation, counting and identification of the mites from buses, private cars and taxis was conducted in Anhui province during May to October. Data were analyzed statistically. Results From 600 samples, mites were detected in 335 samples with the positive rate of 52.2%. Twenty species of mites were founded, attached to 16 genera and 6 families. The analysis of diversity demonstrated that the average breeding density ranged from(11.85?5.01)to(33.60?8.49), the richness index (Margalef index) fluctuated from 0.532-1.525, the diversity index (Shannon-Wiener index) changed from 2.264-3.035, the Pielou index ranged from 1.050-1.264, the species domination index (Simpson index) ranged from 0.296-0.414, Jaccard index were 0.381, 0.211, 0.385. Conclusion The highest average breeding density, richest species, highest diversity indexes and lowest Simpson index were all observed in the habitat of private cars. However, we get the opposite results in those from taxis and buses, and the lowest similarity between those from private cars and buses. The reasons of the contrasting findings may be related to the difference of storage objects, temperature, humidity and human disturbance in various habitats of motors
