摘　　要：目的调查皖北地区人居环境、工作环境及仓储环境中粉螨孳生情况及多样性。方法采用直接镜检法和水膜镜检法分离粉螨,并进行计数、鉴定及数据分析。结果 720份样本中,416份标本检获粉螨,总孳生率达57.78%;共检获粉螨41种,隶属7科20属,其中腐食酪螨为优势种。仓储环境孳生粉螨的物种数、丰富度指数及多样性指数较高,工作环境中相关指数较低;工作环境孳生粉螨的均匀度指数较高,人居环境相关指数较低。结论皖北地区粉螨种类较多,污染严重,其群落结构及多样性与生境条件有直接关系。Objective including human habitat, working environment, and storage habitat in northern Anhui province, China. Methods Acaroid mites were isolated by direct microscopy and water flotation and then counted and identified; the obtained data were analyzed. Results Acaroid mites were isolated from 416 of 720 samples, with a positive rate of 57.78%, including 41 species belonging to 20 genera and 7 families; Tyrophagus putrescentiae was the dominant species. The species number, species richness, and species diversity of acaroid mites were higher in the storage habitat than in the working environment. The species evenness was higher in the working environment than in the human habitat. Conclusion There are many species of acaroid mites in northern Anhui province, and they breed heavily in this area. The habitat condition directly influences the community structure and diversity of acaroid mites.
