摘要
目的调查海南省文昌市境内地脚米粉螨的孳生程度。方法采用直接镜检法分离地脚米样本中孳生的粉螨,将检出的螨制成玻片标本,置于光学显微镜下观察其形态并进行螨种鉴定和计数。结果从采集的20份地脚米中共分离出12种粉螨(5 885只),分别隶属于4科10属。总体平均孳生密度为29.43只/g,其中热带无爪螨和腐食酪螨孳生率较高。结论海南省文昌市地脚米中粉螨孳生密度较高,应采取控制措施。
Objective To investigate the breeding of acaroid mites in the stored grains in Wenchang area, Hainan Province,China. Methods The breeding mites from the samples were separated by a shake-sieve and microscope directly. The isolations were used for slide preparation based on previous literature, and then under a light microscope, the identification and counting of the acaroid mites were performed. Results Twelve species of mites were identified from 20 categories of grains. They belonged to 10 genera of 4 families. Among the 12 grain samples, the breeding rates were higher of Blomia tropicalis and Tyrophagus putrescentiae. Among the 20 samples collected, a total of 5 885 mites were found, with an average breeding density of 29.43/g.Conclusion The infestation of acaroid mites appears serious in the stored grains in Wenchang area, which should be taken measures to prevent and control.
