5. How are silkworms reared according to Chapter 3 of Class 7 Science?
A mother silk moth typically lays approximately a hundred eggs at a time. The silkworm growers buy these eggs, which are carefully preserved on paper or fabric strips. For the eggs to hatch, the farmers maintain an appropriate temperature, humidity, and sanitary environment. The larvae grow in size by eating fresh mulberry leaves throughout the day. The farmers maintain the larvae with the mulberry leaves on bamboo trays with clean, small chambers. After 25-30 days, the larvae stop feeding and enter the small chambers to weave the cocoon. Farmers occasionally supply tiny twigs or racks to such chambers. The pupa grows into the silk moth within the cocoon.
