【摘要】：目的调查齐齐哈尔市地脚粉中纳氏皱皮螨孳生情况。方法从齐齐哈尔市一所高校食堂和15个家庭采集地脚粉共16份,每份样本10 g,分离其中螨类,制成玻片标本,光镜下直接观察螨的形态特征,并进行螨种鉴定、分类。结果从16份样本中检出粉螨的样本有15份,检出率为93.8%,共分离出粉螨7种,隶属于3科6属。160 g地脚粉中检出粉螨561只,平均孳生密度为3.51只/g,纳氏皱皮螨检出率最高。结论齐齐哈尔市地脚粉中有多种螨类孳生,其中纳氏皱皮螨的孳生密度最高,应采取有效防制措施,以降低粉螨污染带来的危害。
[Abstract]:Objective to investigate the breeding of Dermatophagoides natrii in ground foot powder of Qiqihar City. Methods 16 samples of ground foot powder were collected from a university canteen and 15 families in Qiqihar City. The mites were isolated from each sample and made into glass slides. The morphological characteristics of mites were observed directly under light microscope, and the species of mites were identified and classified. Results there were 15 samples of acaroid mites detected from 16 samples, the detection rate was 93.8%, and 7 species of mites were isolated. 561 mites were detected in 3 families, 6 genera, .160g ground foot powder, the average breeding density was 3.51 / g, and the detection rate of Dermatophagoides natrii was the highest. Conclusion there are many species of mites in ground foot powder of Qiqihar city, among which the breeding density of Dermatophagoides natrii is the highest. Effective control measures should be taken to reduce the harm caused by acaroid mites pollution.
