【摘要】:目的了解芜湖市面粉厂地脚粉孳生粉螨的种类及分布情况。方法采集面粉厂不同环境(仓库内、磨粉间、筛粉间、院区内)地脚粉样本,每个生境分别设5个采样点,每个采样点采集地脚粉样本2份,每份10g。采用直接镜检法分离粉螨,制备粉螨的玻片标本,显微镜下直接观察螨体形态特征和测量其大小,对螨种进行鉴定和分类,并计算不同环境粉螨的平均孳生密度和相对丰度。结果从4种生境共采集样本40份(重400g),分离粉螨28730只,平均孳生密度71.83只/g,其中仓库内的平均密度最高,为124.00只/g,院区内的平均密度最低,为26.40只/g。其中以腐食酪螨(Tyrophagus putrescentiae)(7820只)、害嗜鳞螨(Lepidoglyphus destructor)(7220只)和粉尘螨(Dermatophagoi desfarinae)(4590只)居多。共分离鉴定出14种粉螨,隶属于4科10属。其中粉螨科6种,食甜螨科5种,麦食螨科3种,分别为粗脚粉螨(Acarus siro)、腐食酪螨(Tyrophagus putrescentiae)、长食酪螨(Tyrophagus longior)、椭圆食粉螨(Aleuroglyphus ovatus)、食虫狭螨(Thyreophagus entomophagus)、纳氏皱皮螨(Suidasia nesbitti)、家食甜螨(Glycyphagus domesticus)、隆头食甜螨(Glycyphagus ornatus)、米氏嗜鳞螨(Lepidoglyphus michaeli)、害嗜鳞螨(Lepidoglyphus destructor)、棕脊足螨(Gohieria fuscus)、梅氏嗜霉螨(Euroglyphus maynei)、粉尘螨(Dermatophagoides farinae)和屋尘螨(Dermatophagoides pteronyssinus)。仓库、磨粉间、筛粉间和院区内分离粉螨种数分别为10、5、9和4种。结论芜湖市面粉厂仓库内粉螨污染严重,应及时清理地面残留的面粉,减少粉螨孳生;粉螨的种类和分布与温度、湿度、光照、粉螨的食性和人为干扰等因素密切相关,且粉螨的种类和分布是多种因素综合作用的效果。
[Abstract]:Objective to investigate the species and distribution of acaroid mites in ground powder of flour mill in Wuhu city. Methods the samples of ground foot powder in different environment (warehouse, grinding room, sieve room, hospital area) of flour mill were collected. Five sampling points were set up in each habitat, and two samples of ground foot powder were collected from each sampling site, each 10 g. Acaroid mites were isolated by direct microscopic examination, and the glass specimens of acaroid mites were prepared. The morphology and size of mites were observed and measured directly under microscope. The mites were identified and classified, and the average breeding density and relative abundance of acaroid mites in different environments were calculated. Results A total of 40 samples were collected from 4 habitats (weighing 400g / g, 28730 mites were isolated, the average breeding density was 71.83 / g), the average density in warehouse was the highest (124.00 / g), and the average density in hospital was the lowest (26.40 / g). Most of them were Tyrophagus putrescentiae)(7820, Lepidoglyphus destructor)(7220 and Dermatophagoi desfarinae)(4590. A total of 14 species of acaroid mites were isolated and identified, belonging to 4 families and 10 genera. Among them, 6 species of acariidae, 5 species of sweet acariidae, 3 species of wheat eating acariidae, 鍒嗗埆涓虹矖鑴氱矇铻,
