摘　　要：目的调查安徽省粉螨的物种组成多样性。方法对每个城市选取储藏环境中的储粮、经济作物和干果等进行粉螨标本的采集、鉴定、计数及数据分析。结果共检获粉螨31种,隶属于7科20属。自北而南的淮北平原、江淮丘陵、皖中平原、皖南山地中,皖南山地平均孳生密度最高为46只/g,物种丰富度指数为1.38,物种多样性指数为2.7,物种均匀度指数为0.92。结论安徽省粉螨污染储藏物的情况较为严重,粉螨群落组成较为多样化,应采取有效防螨措施。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.
