Sericulture and Apiculture
India is an agro-based country. Agriculture, animal husbandry and dairy farming arethe core occupations of the country’s inhabitants. Besides this, many farmers perform sericulture and apiculture.
Sericulture is the practice of rearing of silkworms artificially on mulberry farms to produce raw silk. In sericulture, a moth species Bombyx mori is cultivated and raised under controlled environmental conditions.to obtain silk from the silk worm, first silkworms are fed on mulberry leaves. Cocoon produced from silkworm are put in frames. Before the moth comes out, cocoons are put into boiling water. At this stage pupa dies and silk threadsare obtained.
Life cycle of silkworm includes four stages;that are egg, larvae, pupa and moth.Silk is obtained from cocoon (or pupa stage).The important varieties of silk fibre produced in India are Mulberry, Tassar, Eri and Mugga.Silkworms may be affected by various protozoans, viral, bacterial, fungal diseases. These diseases are pebrine, bacterial oacherie, flacherie disease andmuscardine.
Therefore, proper cleanliness and hygiene in the rearing area is required.
Apiculture is the rearing of honey bees for the production of honey and other useful products on a commercial scale. Some indigenous species of honey bee areapisdorsata, apisindica and apis florae.Honey can be cultured artificially in a man-made behive or apiary. Based on roles, the three castes of honey bees are workers, drones and queen. Products obtained by apiculture are honey and beewax. They serve as important ingredients in pharmaceutical and cosmetic industry. Honey obtained from bees is of high nutritive value and is easily digestible.Honey bee may suffer from various bacterial, viral, fungal or protozoan diseases.Besides, honey bee may be affected by enemies such as wasps, mites, wax moths, crows, tits, fly catchers, sparrows, bee eater, etc.
