Abstract:

Objective To investigate the breeding of acaroid mites in room air conditioners in Wuhu, China. Methods Dust was collected from the dust screens of the cabinet air conditioners and wall-mounted air conditioners used by Wuhu residents from June to October 2012. The mites breeding in the dust were classified and identified, and the mites of each species were counted. The mite breeding rates were compared by chi-square test. Results A total of 202 dust samples were collected from the dust screens of air conditioners; 3265 mites, including 2796 acaroid mites, were detected from the dust samples, and they were identified as 18 species, 14 genera, and 6 families. The mean breeding density was 10.39 mites/g of dust, and the breeding rate was 70.79%. The mite breeding rate for the cabinet air conditioners was 58.73%, versus 76.26% for the wall-mounted air conditioners (χ²=6.442, P<0.05). Pyroglyphidae, Acaridae, and Glycyphagidae were commonly seen and accounted for 53.47%, 20.96%, and 18.13% of the total tmites, respectively. Conclusion In Wuhu, acaroid mites breed heavily in the dust screens of cabinet air conditioners and wall-mounted air conditioners, with high species diversity.

摘要：

目的 了解芜湖地区居室内空调粉螨的污染情况。方法 于2012年6－10月采集芜湖市居民家用柜式空调和壁挂式空调隔尘网的灰尘,对孳生的螨类进行分类鉴定,并按种统计个体数。率的比较采用χ²检验。结果 共收集202份空调隔尘网积尘样本,检出螨类3265只,其中粉螨2796只,隶属6科14属18种;平均孳生密度为10.39只/g,孳生率为70.79%;柜式空调隔尘网积尘中螨类孳生率为58.73%,壁挂式空调螨类孳生率为76.26%,二者差异有统计学意义(χ²=6.442,P<0.05)。麦食螨科、粉螨科和食甜螨科构成比较高,分别为53.47%、20.96%和18.13%。结论 芜湖地区柜式空调和壁挂式空调隔尘网粉螨孳生情况严重,物种多样性丰富。
