Abstract:

Objective Objective To observe the external morphology of Histiostoma feroniarum hypopus under light microscope. Methods Methods The samples were collected in a mushroom cultivation base，and the Histiostoma feroniarum hypopus was isolated and purified. The slide samples were prepared and observed under an optical microscope. Results Results The back body of the His? tiostoma feroniarum hypopus was flat with tiny bristles，the epidermis was of significant ossification，the ventral had four pairs of slender feet stretched，the sucker plate was prosperous in the end of the body，and the sucker plate had eight suckers. The gnathosoma was thin，long and highly specialized. Conclusion Conclusion The light microscopy shows the morphological characteristics of Histiostoma feroniarum hypopus，providing the basis for identifying the hypopus.

摘要：

目的 目的 光镜下观察食用菌速生薄口螨休眠体形态。方法 方法 采集某食用菌栽培基地的食用菌样本， 分离其中的速生薄口螨休眠体， 纯化并洗净。制备玻片标本， 光镜下观察速生薄口螨休眠体形态。结果 结果 光镜下可见速生薄口螨休眠体背面躯体扁平， 有细小刚毛， 表皮有明显骨化； 腹面可见4对前伸细长足， 躯体末端吸盘板发达， 板上有8个吸盘， 颚体细而长且高度特化。结论 结论 光镜下观察了速生薄口螨休眠体的形态特征， 为其休眠体鉴定和生物学分类提供了参考依据。
