摘要:

目的 调查面粉厂地脚粉中皱皮螨的孳生情况,并进一步对比观察其形态特征。方法 从面粉厂不同的生境中采集样本,用分样筛分离样本,留取碎屑部分。在光镜下从碎屑中挑选出螨进行计数,并制作螨玻片标本进行螨种鉴定。结果 经分离、鉴定,在淮北某面粉厂的地脚粉样本中检出了纳氏皱皮螨和棉兰皱皮螨。共采集地脚粉样本20份,其中13份检出了皱皮螨,检出率为65.0%。共在200 g地脚粉样本中检出皱皮螨2 876只,样本中的皱皮螨平均孳生密度为14.38只/g。结论 皱皮螨在面粉中孳生较普遍,因其可引起人体螨病及螨过敏性哮喘等,故应采取必要的防治措施。

Abstract:

Objective To investigate the Suidasia breeding in the flourmill and further observe its morphological characteristics. Methods The samples were collected from different habitats of a flourmill and then separated, and the chipping was kept. The mites were selected and counted from the chipping under an optical microscope. The mites were made slide samples and identified. Results The mites were identified as Suidasia (including Suidasia nesbitti and Suidasia medanensis). A total of 20 samples were collected in this study, of which 13 were positively detected, with the detection rate of 65%. There were 2 876 mites of Suidasia that were detected from 200 g sample. The average breeding density was 14.38/g. Conclusions It is common that Suidasia breeding in flour, which might cause human acariasis and allergic asthma. Therefore, the effective prevention measures should be taken.
