添加维生素C对4龄柞蚕幼虫的影响

Effects of Vitamin C Supplementation on 4th Instar Larvae of Antheraea pernyi

维生素C(Vitamin C)是柞树叶添加营养剂和柞蚕人工饲料中的重要成分,本文通过添食和注射两种方式,研究维生素C对柞蚕生长发育的影响。试验结果表明,添加维生素C能提高柞蚕抗性,但剂量太高会引起代谢紊乱;添食时间在4龄起蚕较为适宜,最佳剂量均为每克体重0.2mg;注射比添食效果更直接,注射后6～12h是促进维生素C代谢的主要时间段,最佳剂量为每克体重0.02mg。

Vitamin C （Vitamin C） is an important component of oak leaves supplemented with nutrients and artificial diet for tussah. In this paper, the effects of vitamin C on the growth and development of tussah are studied by feeding and injection. The results show that adding vitamin C can increase the resistance of tussah silkworm, but too high dosage would cause metabolic disorder. The suitable feeding time is the 4th instar, and the best dosage is 0.2mg/g body weight; it is more effective to do injection than feeding ; vitamin C is metabolized mainly after 6 12h of injection , and the best dosage is 0. 02mg/g body weight.
