There are many species of silkworms, which are used for commercial purpose, but the caterpillar of the silkworm, which is domesticated also called as Bombyx Mori is the silkworm which is widely in use.

Starting a silkworm farm is a very important part of sericulture. There should be great care and proper management. Based on the number of broods, they are categorized as below:. The silkworm is very suitable in tropical climates because the mulberry plant will go well in the regions which have tropical climatic conditions and give a good yield all around the year.

Depending on the age of the silkworm, the silkworm rearings are classified into two types. The life cycle of a silkworm will have to go through five instars. It is your choice to choose until which stage you want to rear your silkworm. The environmental conditions should be proper while rearing the silkworm and proper care has to be taken.

By following the above environmental conditions, the hatching would take place in a uniform way with two weeks from the day the eggs were first laid.

The egg will be brushed to the rearing bed as soon as the larva comes out it. Then the leaves should be cut to a size of 1 cm each and should be spread on the bed.

Moulting is nothing but the shedding of the skin, which is old, and the formation of the new skin. When the silkworm gets through the second instar, it goes through the stage of moulting. The third instar is the stage which is the most critical one and it occurs between young age worm rearing and late age worm rearing. This stage starts after the third instar. In this stage, the worms feed on more leaves. Before this stage gets started, the rearing room should be made clean along with the equipment.

The equipment should be cleaned in such a way that it gets rid of all the disinfectants. The leaves which are harvested should have less moisture content and the carbohydrate content of the fibers should also be less. In this late age stage, it should have the environmental conditions which are controlled and you can have a look at those below. From disease-free eggs, there would be a yield of 45 kgs with chowki rearing and a yield of 50 kg with late age worm rearing.

The yield should be having a shape and size, which is uniform and the content of silk should have a good weight of the shell. To complete this process, it takes a month.

This process usually starts with the selection of the cocoon, the next step would be cooking and the final step would be silk reeling. Coming to the selection of cocoon, to reel the silk, this step is very much important. A cocoon that is good will give a very good yield of silk fiber. The cocoon which you opt for should have the below features:.

After selecting the cocoon, you need to steam it so that the insect which is present inside it will die without causing any sort of damage to the cocoon. The insect should be killed when it is inside the cocoon because if it comes out, there would be a discontinuity in the silk fiber and you will not be able to reel the fiber which is lengthy. After this, by using hot water, soak the cocoon.

The temperature of the water, which is used for soaking should be between 93 to 95 degrees Celsius.
