龙蛓(ci)天蚕 Rhodinia togax Butler 是在大别山区发现的一个野生蚕种。经鉴定,在昆虫分类学上属鳞翅目 Lepidoptera 大蚕蛾科 Saturniidae。通过系统研究掌握了它的生态特征、形态特征及生物学习性。茧丝物理性能测定,纤度1.26D,干断裂强度6G/D,干断裂伸长率为45%。茧丝化学成分中的氨基酸总量为82.75%,各种氨基酸的比例不同于其它蚕种。茧丝蛋白质分子结构的红外光谱出现3300cm~(-1)、1650cm~(-1)、1520cm~(-1)、1235cm~(-1)、960cm~(-1)、600～700cm~(-1)谱峰。这些工作为野蚕驯化饲养和茧丝开发利用提供了理论依据。填补了国内龙蛓天蚕研究的空白。
Dragonfly (ci) silkworm Rhodinia togax Butler is a wild silkworm species found in the Dabie Mountains. It has been identified as belonging to the order Lepidoptera Lepidoptera Saturniidae in insect taxonomy. Through systematic research it has mastered its ecological characteristics, morphological characteristics and biological learning. The physical properties of the silk yarn were measured, with a fineness of 1.26 D, a dry breaking strength of 6 G/D, and a dry breaking elongation of 45%. The total amount of amino acids in the chemical composition of silk is 82.75%, and the proportion of various amino acids is different from other silkworm species. The infrared spectrum of silk protein molecular structure appears 3300cm-1, 1650cm-1, 1520cm-1, 1235cm-1, 960cm-1, 600-700cm. 1) Spectrum peaks. These work provide the theoretical basis for the domestication of wild silkworm and the development and utilization of silk. Filled up the gaps in the research of the Chinese dragon larvae.
