Describe the rearing of silkworm?
Answers
In the beginning, the female silk moth lays hundreds of eggs. These eggs are stored over a clean paper or piece of cloth. These eggs are then sold to the silkworm farmers. The farmers then keep the eggs under the accurate temperature and humidity at a clean place. They are warmed to the most appropriate temperature to hatch eggs to produce larvae or caterpillar. This process is done when the mulberry trees have fresh crop of leaves. The caterpillar eats this mulberry leaves day and night and it grows in size. Bamboo trays are used to keep these caterpillars and some freshly chopped mulberry leaves are kept in the tray. After 30-40 days approximately the caterpillars stop eating the leaves and then it moves inside the small chambers in the bamboo trays to spin cocoons. These are produce by the secretion of liquid protein from their salivary glands. Small racks are given in the trays so that the cocoons get attached to those racks. Silk moths are developed inside the cocoons.
