A significant-source of allergens come from house dust that contain particles derived from arthropods, molds, and pet dander. This study evaluated mite and booklouse fauna from vacuumed dust samples in Beijing China (a temperate zone). Our survey was carried out in Beijing in the homes of mite allergic patients who visited our Allergy Department. In total, 38 homes were selected for the collection of dust samples by vacuuming, from December 2008 to January 2010. The flotation method was used to isolate mites from house dust. Permanent slides were prepared for mite specimens and mites were identified and counted under a microscope. In total, 1,798 separate mite and insect specimens were found in 345 dust samples taken from 38 homes. A total of 95 individual Dermatophagoides (D) siboney were detected in 35 dust samples from 19 homes (representing 5.3% of all mite and insect species found in house dust); in addition, this mite was found to co-exist with D. farinae (Hughes, 1961) in 33 dust samples. Our results demonstrated the presence D. siboney that co-existed with D. farinae in house dust in Beijing China (a temperate zone).
过敏原的一个重要来源是屋尘，其中含有节肢动物、霉菌和宠物皮屑的颗粒。本研究评估了来自中国北京（温带地区）真空吸尘尘样中的螨和书虱区系。我们的调查是在北京对来我院变态反应科就诊的螨过敏患者的家中进行的。从 2008 年 12 月至 2010 年 1 月，共选择了 38 户家庭进行吸尘采集尘样。采用漂浮法从屋尘中分离螨。为螨标本制备永久载玻片，并在显微镜下对其进行鉴定和计数。从 38 户家庭的 345 个尘样中总共发现了 1,798 个单独的螨和昆虫标本。从 19 户家庭的 35 个尘样中总共检测到 95 个单个的鳞足螨（D）siboney（占在屋尘中发现的所有螨和昆虫种类的 5.3%）；此外，还发现这种螨与粉尘螨（D. farinae（Hughes，1961））共存于 33 个尘样中。我们的结果表明，鳞足螨与粉尘螨在中国北京（温带地区）的屋尘中共同存在。
