目的了解小颚螨的形态结构特征,创建在我国发现此螨的新纪录。方法采集居民家中储藏的粮食(大米和黑米),分离其中孳生的螨,并参照有关文献制作标本和进行螨种鉴定,并依据Hughes分类方法进行螨种分类。结果在采集的样本中发现了小颚螨。光镜下观察,可见小颚螨躯体卵圆形,雄螨比雌螨更圆,且有膨腹现象,前足体板似三角形,前缘覆盖颚体;足Ⅰ4节,跗节与胫节愈合成为粗短的胫跗节;足Ⅱ~Ⅳ5节,末端有1前跗节,每足具1爪。结论初步了解了小颚螨的形态结构特征,为进一步研究此螨奠定了基础。
Objective To understand the morphological characteristics of the malachite mites and to create a new record of this mite found in China. Methods The grains (rice and black rice) stored in households were collected, the mites were isolated, the specimens were made and the mites were identified with reference to the relevant literature, and the mites were classified according to Hughes classification. Results Small-jaw mites were found in the collected samples. Light microscopic observation, we can see the body of omales Otorii mite, male mites than round female mites, and the phenomenon of bulging abdomen, the former plate like a triangular triangle, the leading edge covering the jaw; foot Ⅳ section, joint and tibia healing Become stubby tibiofibrosis; foot Ⅱ ~ Ⅳ5 section, the end of an anterior section, each with 1 claw. Conclusion Preliminary understanding of the morphological structure of the mite mites laid the foundation for further study of this mite.
