![]() Diet supplements containing fatty acids and carbohydrates were shown to have a regulatory effect on fatty acid synthesis in larval stages of B. The presence of casein in a diet has enhanced the growth rate of Manduca sexta caterpillars and was observed to stimulate the feeding efficiency of B. Casein contains fatty acids, cholesterol, sugars, vitamins, and minerals ( Vanderzant 1966). 2011).Īrtificial diets rich in amino acids are required for optimal growth of an insect, and casein has been widely used as it contains all amino acids ( Panizzi and Parra 1991). The growth and development of larvae, and subsequent cocoon production, are greatly influenced by the nutritional quality of mulberry leaves ( Masthan et al. Mulberry leaves enriched with nickel chloride and/or potassium iodide have increased cocoon weight at low concentrations ( Islam et al. Different combinations of mineral nutrients were found to improve larval growth and silk production ( Ahmad 1993). The protein content of the silk gland, fat body, and muscles was found to increase significantly when larvae were fed with ascorbic acid ( Quraiza et al. mori has been studied ( Khan and Saha 1995 Nirwani and Kaliwal 1998 Radjabi 2010 ). The effect of mulberry leaves enriched with amino acids on the growth of B. In order to make sericulture more economically viable, it has become important to study and analyze various factors that improve growth, yield, fiber quality, and larvae's resistance to pathogens.Įnriching mulberry leaves by nutrient supplementation is one of the ways to improve growth rate in B. Many people in India are involved in sericulture, which involves a great deal of labor and intensive care. (Rosales: Moraceae), and serves as an excellent model system because of its life cycle, it is inexpensive, and there are no ethical issues involved ( Hiroshi et al. mori feeds on the leaves of the mulberry tree, Morus L. (Lepidoptera: Bombycidae), which is native to Asia and spins a cocoon of fiber that is the source of commercial silk. Silkworms are larvae of the moth Bombyx mori L. mori larvae can be fed mulberry leaves treated with bovine milk for better growth rate and increased silk production. In addition, cocoon weight increased by 8% when milk was added compared to when it was not. The larvae fed with milk-treated leaves gained 310% weight from day 1 to day 7 of the fifth instar, while the larvae fed with fresh leaves gained 153% weight in the same timespan. The results showed that larvae gained 82.5% more weight by the end of fifth instar larval when fed with mulberry leaves dipped in milk than when fed with fresh mulberry leaves without milk. Cocoon weights were measured, as the weight indicates the approximate amount of silk that can be reeled. Treatments were given on alternate days, and the silkworms were weighed every day to determine whether milk had any role in enhancing the weight of the larvae. (Rosales: Moraceae), leaves and mulberry leaves dipped in milk from the first day of the fifth instar. The larvae were treated with fresh mulberry, Morus L. mori eats voraciously and shows maximum growth among all its larval stages. mori larvae because the fifth instar period is when B. The treatment was given to fifth instar B. Bovine milk contains several components that aid in healthy growth. In this study, the effect of bovine milk on B. mori because it's larvae, silkworms, are vital in the production of silk. Many scientists have placed importance on enhancing the economic traits of B. (Lepidoptera: Bombycidae) is a well-studied Lepidopteran model system because of its morphology, life cycle, and economic importance.
