摘　　要：目的调查安徽省宣城地区居室环境中粉螨的群落组成和多样性。方法于2006年6—7月,选择100户家庭进行了样本采集,每居室环境中取4个采样点,分别采集地面灰尘、床面灰尘、家具灰尘及衣物灰尘,采用振筛分离、直接镜检等方法进行灰尘样本中粉螨的分离、鉴定及计数,并进行数据分析。结果共检获粉螨3 386只,隶属于6科12属,共14种。对4类居室灰尘中粉螨群落多样性分析表明:它们的丰富度指数为0.73～1.75,多样性指数为1.36～1.87,均匀度指数为0.70～0.92。结论粉螨群落的结构及多样性与其生境条件直接相关,人类活动的干扰也是不可忽视的影响因素。Objective To investigate the composition and diversity of acaroid mite community in the house in Xuancheng area in Anhui province. Methods The dust samples from 4 sites selected in each house were collected in June-July, 2006, acaroid mites were isolated, counted and identified. Results 3 386 acaroid mites were obtained, belong to 6 families, 12 genera and 14 species. The species richness index Rmargalef for the four habitats ranged from 0.73 to 1.75, while the species diversity index （Shannon-Wiener index） ranged from 1.36 to 1.87 and Pielou index ranged from 0.70 to 0.92. Conclusion The results of the present paper show that the habitat Condition is the main factor that can directly influence the community structure and diversity of acaroid mites in the houses and the human activity is also an influencing factor to be reckoned with.
