柞蚕青六号品种幼虫腹足趾钩的研究

Studies on the Crochets on Abdominal Legs of Larvae of Chinese Tusser (Antheraea Pernyi Guerin Meneville)

记述了柞蚕六号品种幼虫腹足趾钩的形态特征和排列方式,对各龄、各对腹足胤钩的数量和长度进行统计分析,发现中国柞蚕与由中国引进的日本柞蚕幼虫腹足趾钩的排列、长度及数量存在着明显的差异,为从形态学方面探讨中国柞蚕地理种分化提供重要线索。

This article describes the morphological characters and pattern of arrangement of crochets on abdominal legs of larvae of the Chinese Tusser Race Qing 6. The length and number of crochets were statistically analysed on each pair of abdominal legs at all instar stages It is discovered that there is significant defference in the arrangement length and number of abdominal legs on larvac between Chinese Tusser and Tusser intrduced from Japan which provides an important clue for studying the differenti- ation of geographical race of Chinese Tusser in its morphological context.
