Abstract: Objective Objective To observe the external morphology of Histiostoma feroniarum hypopus under a light microscope. Methods Methods The samples were collected in a mushroom cultivation base,and the H. feroniarum hypopus was isolated and puri? fied. The slide samples were prepared and observed under an optical microscope. Results Results The back body of the H. 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 H. feroniarum hypopus, providing the basis for identifying and life cycle study.
摘要: 目的 目的 观察洋葱害螨速生薄口螨形态。方法 方法 采集储藏洋葱样本, 采用直接镜检法和水膜镜检法分离其中孳 生的速生薄口螨, 制备玻片标本, 光镜下观察速生薄口螨形态。结果 结果 光镜下可见速生薄口螨成螨近长椭圆形, 体后缘 略凹。颚体小而高度特化。腹面足Ⅰ表皮内突愈合后成为胸板, 足Ⅱ内突伸至中央, 未连接, 向后弯, 有几丁质环2对, 位于足Ⅲ~Ⅳ基节之间的生殖孔前。在足Ⅰ跗节上, 除背毛d外, 所有的刚毛均加粗成刺; 足Ⅰ、 Ⅱ胫节的感棒φ短且不 明显。体背有一条显明的横沟。足Ⅰ~Ⅲ基节有基节上毛。每足末端为粗爪。雄螨生殖感觉器缺失, 可见其阳茎。在两 个几丁质环之间有一横缝为雌螨生殖孔。休眠体通常会有吸盘板, 8对吸盘位于吸盘板上。结论 结论 储藏洋葱存在速生 薄口螨污染, 研究速生薄口螨的形态特征, 对进一步研究其分类和生活史具有重要价值。
