Question

Apart from silk, there are several other bye-products from sericulture. The

mulberry fruits are rich in minerals and vitamins and from the roots, barks

and mulberry leaves several ayurvedic and herbal medicines are prepared.

Some of the woody mulberry trees provide timber which are resistant to

termites and the timber is used for making sports items, toys etc. The

mulberry branches after silkworm feeding are generally dried and used as

fuel particularly in the villages. The foliage of mulberry is used as a fodder

for cattle. The mulberry trees are also planted in the embarkment area for

protection of the soil to prevent soil erosion, and mulberry trees are

planted as avenue trees. The silkworm pupae are rich in oil content and

pupal oil is used in cosmetic industry and the remaining pupal cake is arich source of protein suitable for poultry and fisheries. In some tribal

population, the people eat eri pupa as a source of protein and

nourishment. The silkworm litter is used for bio-gas production and used

as a fuel for cooking in the rural area. Thus sericulture not only provides

silk for fashionable clothings, it also provides several very useful bye

products to the human society. Therefore, sericulture development

provides opportunities to improve the living standards of people in the

rural area in developing countries.
