伯氏嗜木螨休眠体光镜下形态观察

Morphological observation on hypopus of Caloglyphus berlesei by optical microscope

目的了解伯氏嗜木螨休眠体(第二若螨)的结构特征。方法从地鳖虫培养料中采集伯氏嗜木螨的休眠体,将其制作成常规玻片标本,光镜下观察其外部形态特征。结果光镜下可见伯氏嗜木螨休眠体的生殖板、足及胫节毛和膝节毛等结构特征,足的前跗节发达,足爪明显,生殖板明显骨化。结论研究伯氏嗜木螨休眠体形态的细微特征,对进一步研究该螨的分类和生活史具有重要价值。

Objective To understand the structure characteristics of hypopus of Caloglyphus berlesei. Methods The hypopus of C. berlesei was collected from the feed of Chinese Polyphaga, and was made into the conventional glass specimens. The structure characteristics of hypopus of C. berlesei were observed by an optical microscope. Results The hypopus of C. berlesei had 4 pairs of legs, and the foot claws and tarsus were well-developed. The structural features were shown, such as the seae of tibia and setae of genu. Genital plates were obviously ossified. Conclusion The research on hypopus of Caloglyphus berlesei provides the reference for its further scientific classification and research on the life cycle.
