Artificial diet rearing system for the silkworm Bombyx mori (Lepidoptera: Bombycidae): effect of vitamin C deprivation on larval growth and cocoon production

摘要: An artificial diet containing 2% L-ascorbic acid was given to silkworm (Bombyx mori) larvae throughout larval life, or only in some instars order make a comparison of fed on without life. Obtained results show that, when complete deprivation is done during the cycle, it affects growth and cocoon production. Furthermore, absence from food, particularly first last instars, generates beneficial effects production affecting survival rate delaying cycle.
