摘要
目的调查不同环境中粉螨群落的物种组成和多样性。方法选取仓储环境(储藏物和/或地尘)、人居环境(卧室或学生宿舍中的床尘及地尘)和工作环境(纺织厂或制药厂工作车间中的地尘)等3类不同环境各30个采样点,每个采样点各采集样本2份,每份10g,过筛后留取尘渣,进行粉螨的采集、分类、鉴定及计数以及数据分析。结果3类不同环境共检获粉螨26种,隶属于7科19属。多样性分析结果表明:3类环境的粉螨平均孳生密度为15.35±6.133～1.27±8.34,物种数为112～6,物种丰富度指数(Rmargalef)为1.994～.35,多样性指数(Shannon-W iener指数)为2.273～.13,均匀度指数(Pielou指数)为0.950～.96。结论3类不同环境中粉螨的孳生密度及多样性差异较大。
Objective To investigate the composition and diversity of aearoid mite community in Huainan City. Methods Dust samples were collected from storage circumstances, human dwellings and working places. Aearoid mites were isolated, counted and identified. 30 sampling spots from each of the three environments were selected, and 2 samples, each with 10 g, were collected from each sampling spot. Results 26 species of acarid mites were identified from the three environments. These acarid mites belonged to 19 genera, 7 families. Diversity analysis showed that the average breeding density ranged from 15.35±6.13 to 31.27±8.34, the number of species ranged from 11 to 14, the values of the species richness index Rmargalef for the three circumstances raged from 1.99 to 4.35, the species diversity index （Shannon-Wiener index） ranged from 2.27 to 3.13, and Pielou index ranged from 0.95 to 0.96. Conclusion The composition and diversity of aearoid mite community in three different circumstances are different significantly, which might be relevant to temperature, humidity and human interference.
