रेशम कीट का जीवन चक्र | Silkworm life cycle | resham keet ka jeevan chakra |Bombyx mori |Sericulture

In this video, I have told about silkworm moth-Bombyx mori in which this kite survives only for two-three days. In the same time, every moth makes intercourse by planting 300-400 eggs on mulberry leaves. A small caterpillar larvae emerge from each egg in about 10 days. In 30–40 days, as a result of active growth, the larva is first elongated and then becomes sluggish and chubby. Now, for three days, by continuously moving its head, it makes a shell of the same long thread, which is called coya or cocoon, from the matter secreted by its salivary glands around it. On contact with air, this thread becomes dry and becomes silk thread, which is about 1000 meters long. #Silkwormlifecycle#Sericulture#Bombyxmori#
