Abstract: Objective To investigate the breeding status and diversity of acaroid mites in the ground dust flour in some areas of Xuzhou, Jiangsu province, China. Methods Ground dust flour was collected from steamed bun shops, pancake shops, and baked wheat cake shops in a food market in Xuzhou; acaroid mites were isolated from the samples via direct microscopy method and were made into slide specimens for mite species identification and statistical analysis. Results A total of 58 647 acaroid mites were detected from 460 grams of ground dust flour, which belonged to 9 species of 8 genera of 4 families. The dominant species was Tyrophagus putrescentiae. The mean breeding densities of acaroid mites in the ground dust flour of the steamed bun shops, pancake shops, and baked wheat cake shops were 151.70, 116.28, and 71.28 mites/g, respectively, and the mean breeding density was 127.49 mites/g. The species richness, species diversity, and species evenness were highest in the pancake shops, followed by the baked wheat cake shops and steamed bun shops; the species dominance was highest in the baked wheat cake shops, followed by the steamed bun shops and pancake shops; the species similarity of acaroid mites was relatively high between the two of the three sites. Conclusion The ground dust flour in Xuzhou is heavily infested with acaroid mites, which should be given enough attention. Meanwhile, prevention and control measures should be strengthened to reduce mite-induced risks to humans.

摘要: 目的 调查江苏省徐州部分地区地脚粉中粉螨孳生情况及其多样性。方法 采集徐州市某菜市场馒头铺、烙饼铺和烧饼铺的地脚粉,直接镜检法分离粉螨,制成玻片标本,进行螨种鉴定及统计分析。结果 共采集地脚粉460 g,检出粉螨58 647只,隶属4科8属9种,优势种为腐食酪螨。馒头铺、烙饼铺和烧饼铺地脚粉粉螨平均孳生密度依次为151.70、116.28和71.28只/g,平均孳生密度为127.49只/g。物种丰富度、物种多样性、物种均匀度均为烙饼铺>烧饼铺>馒头铺;物种优势度为烧饼铺>馒头铺>烙饼铺;3种场所地脚粉中粉螨物种相似性较高。结论 徐州地区地脚粉有大量粉螨孳生,应予以重视,加强防制措施,降低粉螨危害人类的风险。
