摘要： 目的 了解合肥市某口岸职工食堂储粮间粉螨孳生情况。 方法 采集合肥市某口岸 2 个职工食堂储粮间的地脚粉和地脚米样本,每个储粮间采集 10 份样本,其中地脚米 5 份,地脚粉 5 份。 用直接镜检法分离样本中的粉螨,制作成玻片标本,显微镜下观察其形态特征并进行螨种鉴定及计数。 结果 20 份样本中均检出粉螨,检出率为100%;共检出 5 种粉螨,即腐食酪螨(Tyrophagus putrescentiae)、纳氏皱皮螨(Suidasia nesbitti)、害嗜鳞螨(Lepidoglyphus destructor)、粉尘螨(Dermatophagoides farinae)和屋尘螨(D. pteronyssinus);共分离出粉螨 986 只,平均孳生密度为 4. 93 只 / g,地脚粉样本中粉螨的平均孳生密度高于地脚米样本,腐食酪螨的平均孳生密度最高,为 2. 18 只 / g。结论 合肥市某口岸职工食堂储粮间均有粉螨孳生,应加强对粉螨的防制,预防人体螨病。

Abstract: Objective To understand the breeding status of acaroid mite in the storage room of staff canteen at a port in Hefei City. Methods Five samples of ground dust and 5 aliquots of ground rice were respectively collected from the grain storage rooms of two staff canteens at a port in Hefei. The mites were isolated from the samples by direct microscopy,and prepared into slide specimens,and then observed for the morphology under a light microscope,with the number counted. Results Acaroid mites were detected in the total 20 samples,with a detection rate of 100%. Five species of acaroid mites,including Tyrophagus putrescentiae,Suidasia esbitti,Lepidoglyphus destructor, Dermatophagoides farinae and D. pteronyssinus, were detected. A total of 986 acaroid mites were isolated from the samples. Average breeding density was 4. 93 capita per gram samples,and higher in ground flour than in ground rice. The average breeding density was up to 2. 18 capita of Tyrophagus putrescentiae per gram samples. Conclusion Our findings suggest that acaroid mites are breeding in the storage room of staff canteen at a port in Hefei City,and we should enhance the control measure to prevent incidence of acariasis.
