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。
Objective To investigate the Suidasia nesbitti breeding status in the ground dust flour collected in Qiqihaer City. Methods Totally,16 aliquots of ground dust flour were respectively collected from a college canteen and 15 households in Qiq-ihaer City. Then 10 g dust flour was taken from individual sample for isolation of the mites that were made of slide specimen,and the mites were identified and classified under a microscope. Results Acaroid mites were found in 15 of the 16 aliquots of sam-ples（detection rate being 93.8%）,and 7 species,belonging to 6 genera under 3 families,were identified. A total of 561 heads of mites were isolated from 160 g samples,with an average breeding density of 3.51 heads/g. The most breeding mite was associ-ated with S. nesbitti. Conclusions Various species of mites are breeding in the ground dust flour in Qiqihaer City,and S. nesbit-ti occurs the most. These findings indicate that effective measures should be taken to prevent and control the harm associated with acaroid mite contamination.
