what is sericulture in science

The silk gland is very simply organized as a one-cell layered glandular epithelium that comprises two distinct types of secretory cells, the one that produces fibroin and the other that synthetizes sericins, the two components of silk. It flies after its wings are completely dry. Interactions among different components of a farming system. Among the four varieties of silk produced, as in 2012–2013, Mulberry accounts for 79% (18,715 MT), Tasar (tropical and temperate) 7.3% (1729 MT), Eri 13.2% (3116 MT), and Muga 0.5% (119 MT) of the total raw silk production of 23,679 MT. To cook in water, just below boiling temperature. Farming systems in India and other developing countries are mostly subsistence in nature. ... Sericulture is the process of raising silkworms for their silk. Conceptually, IFS involves a blend of inter alia crops, animals, poultry, pisciculture, bee keeping, sericulture, mushroom cultivation, and agroforestry. Directorate of Sericulture and Weaving of Meghalaya helps in promotion and management of Sericulture Serico in Greek means Silk, and Culture in English means Rearing which together makes Sericulture.

The species of silkworm usually raised by sericulturists is B. mori (Lepidoptera: Bombycidae). Silk farming, i.e. Lesions form on intersegmental membranes, causing them to swell and look like bamboo segments. Minute powdery scales cover the entire body. what do you mean by sericulture respiration in organisms. The by-product of dairying (cow dung) forms a major raw material for bio-gas plants. Sericulture is both an art and science of raising silkworms for silk production. The duration of … The enterprises exist mainly in natural form based on their complementarity. In this process the silkworms are rare and cultured so as to obtain silk fibers from them. The Indian Institute of Natural Resins and Gums, Ranchi (Jharkhand), and the All India Coordinated Research Project on honeybees and crop pollinators have time-tested contributions in the promotion of these two important rural enterprises. It is used in the insulation coil for telephone, wireless receivers and tyres of racing cars. Pasteur showed that the disease could be passed by contact with diseased caterpillars, by contaminated food, and even from mother to offspring through the egg. Meaning of sericulture. FIRST SEMESTER PAPER – 1: GENERAL SERICULTURE AND MORICULTURE Objectives: (i) To introduce the concepts of origin, growth and study of Sericulture as science. Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Hence sericulture or silk production is dependent on moriculture. It neither feeds nor moves and if permitted to live, it undergoes active metamorphosis and becomes an adult in about 10-12 days. As a general term, it covers all forms of garden management, but in ordinary use it refers to intensive commercial production. An apiary, apart from providing a wholesome food product such as honey, plays a role in improving pollination. In sericulture, nosotoxicosis occurs when silkworms consume or are exposed to insecticide-contaminated mulberry leaves, a common problem during the summer-to-autumn rearing period. During the last larval stage (fifth instar), the silk gland produces the silk for the cocoon from a pair of curved glands found on the ventral side of the digestive tube. Larvae may die halfway through the molting process or without molting. The concept of conservation and recycling of energy and mineral matter in the soil-plant-animal-atmosphere continuum is followed. He also studied a second disease, flacherie, which he thought to be caused by a bacterium. Amongst species of silkworms, Bombix mori is the most widely used. The body is divided into head, thorax and abdomen. Pupa is completely inactive. Share with your friends. This has resulted in the rearing of silkworms and cultivation of mulberry trees generally forming a single enterprise. B.Sc. A cocoon is an oval- to football-shaped object made by a mature silkworm larva by spinning silk proteins; the silkworm larva develops into a pupa inside it. The thread can then be twisted into silk yarn or woven into silk cloth (fabric). Digested slurry from bio-gas production forms a useful feed for pisciculture by increasing plankton growth, as well as supplying valuable manure to raise the productivity of field crops and enrich the soil. How to say sericulture. The head bears a pair of compound eyes and a pair of feathery antennae. Strains of B. mori have been bred specifically for mass-rearing under sterile conditions using artificial diet, and can be used to harvest expressed proteins directly from the hemolymph before the virus kills the host. Properly the sericulture deals with the mulberry cultivation, rearing of silkworms, production of cocoons, extraction and reeling of silk fibres. Science Secondary School +5 pts Answered What is sericulture? In cold, the eggs don’t hatch for a long time and the increase in temperature causes them to hatch faster. Both male and female silkworms digest and absorb about two thirds of the nitrogen in the mulberry leaves they consume, and high percentages of the digested and absorbed nitrogen (66% in females and 70% in males) are utilized in the production of cocoon protein. Agriculture is the process of producing food, feed, fiber and many other desired products by the cultivation of certain plants and the raising of domesticated animals (livestock).
