Current Trends in Biotechnology and Pharmacy

The effect of dietary L-glycine (gly) on the growth and production of pupa and cocoon of the Nistari variety of silk worm Bombyx mori was investigated. Different treatment schedules (2% and 3% gly smeared on the mulberry leaves with once and twice supplementation from 1^st and 2^nd day of V^th instar larvae) were performed with suitable controls. The growth of the larvae and silk gland weight were significantly increased with gly supplementation. L-gly supplementation also enhanced the cocoon and pupa production. However, gly was found to have specific effects on the growth and production of pupa and cocoon of Bombyx mori.
