储藏小麦中发现小粗脚粉螨休眠体

Acarus farris hypopus found in stored wheat

目的观察小粗脚粉螨休眠体形态特征。方法采集小麦样本,采用振筛分离法和直接镜检法分离小麦样本中孳生的螨,并制成玻片标本,于光镜下进行形态观察和螨种鉴定。结果在所采集的小麦样本中发现了小粗脚粉螨休眠体。镜下观察显示,该休眠体前足体与后半体分界明显,后半体刚毛较短,腹部具有一吸盘板。结论储藏小麦中孳生有小粗脚粉螨休眠体,其形态特征与粗脚粉螨休眠体相似。

Objective To observe the morphological characteristics ofAcarusfarris hypopus. Methods The breeding mites from stored wheat samples were separated by a shake sieve and direct microscope. The isolations were used for slide preparation, and then the slide was observed under a light microscope for mite identification. Results The A. farris hypopus was found in the collected wheat samples. Under the microscope the boundary between the propodosoma and hysterosoma of the hypopus was obvi- ous. The bristles on the hysterosoma were short, and the abdomen had a sucker plate. Conclusion There is A. farris hypopus breeding in the storage wheat, and its morphological characteristics is similar with the characteristics of A. siro hypopus.
