Composition and diversity of Acaroid mites community in stored food in Anhui area

Objective To investigate the composition and diversity of Acaroid mite community in stored food in Anhui area. Methods Samples were collected from stored food, economic crop and dry fruits in every city in Anhui area. Then the Acaroid mites were isolated,identified and counted;the data was analysed. Results 31 species of Acaroid mites were found,which belonging to 7 families and 20 genera. In those area including Huaibei Plain, Jianghuai hills, Wanzhong Plain and Wannan moutainous region, Wannan showed the highest average breeding density of Acaroid mites of 46/g, with the species richness index being 1.38, the diversity index being 2.7, and the evenness index being 0.92. Conclusion The compsition of Acaroid mites community in stored food of Anhui takes on diversification. The pollution was serious and more effective measures shound be taken.
