b) Silkworm rearing on host plants. 1.5). L. Egg incubation system. They are then washed in hot water to remove the alkali, after which they are flattened and dried in the sun. The cocoons are then boiled in alkaline solutions and then worked with fingers for extraction. This Research Article is an effort to study the relative variations in respect of rearing performances and to study the impacts of zonal differences on the productivity and qualities of tasar cocoons of three mutant strains viz; Daba–blue, Daba–yellow and Daba–almond of tasar silk worm, A. mylitta D. Results obtained are indicative of the fact that the three mutant strains of Tasar Silk Worm differ among themselves in respect of their rearing … Silk producers, both rearers of silkworms and artisans of silk fabrics of the region are a badgered lot. In summer they remain in the pupa stage for nearly 3 weeks. Munis Entomology & Zoology, 14 (2): 629-633] ABSTRACT: The rearing performance of sixteen hybrid combinations were evaluated to find out the superior hybrids. The worms require an ambient temperature of around 27°C and relative humidity of around 70%, adequate ventilation with adequate lighting and protection from insects, pests and fires have to be ensured. The worm stays inside the cocoon for about 10 days to finally emerge as an adult moth. BROAD SEGMENTS OF TASAR SUB-SECTOR 1. 6 NON MULBERRY SILKWORM AND MULBERRY REARING REQUIREMENTS Fig. high temperature treatment of the pupae. d) Marketing of Yarn and Fabric. Integrated Package of late age silkworm rearing. It is well-known since the days of ancient Kamarupa – ancient Assam. Muga silk is unique to Northeast India where it originated. As they grow in size, they molt four times bigger. 1. Commercialization of Oak tasar silkworm, Antheraea proylei 2. Therefore, special rearing houses are constructed to ensure that these conditions are met. The thread breaks when this happens. Evaluation of oak tasar silkworm hybrids in different seasons for improvement in productivity. (2013) reported that one of the main constraint in tasar culture is … Only during the egg-laying process, rearing is done indoors on small sticks or sun grasses. There are four varieties of silkworms in India, accordingly sericulture is classified into Mulberry Culture, Tasar Culture, Muga Culture and Eri Culture, and each one is described separately in the worms, ii) rearing of silk worms, and iii) reeling and spinning of silk. Indoor rearing of chawki silkworm larvae was conducted using glass bottles. Sericulture is an art of rearing silkworm for the production of cocoons which is the raw material for the production of silk. Mulberry leaves are harvested and chopped into fine pieces to feed the larvae. The traditional tasar reasers usually utilize the sparsely distributed food plants on the bunds of paddy fields. In this method of silkworm rearing, the last 3 stages of rearing will be conducted by giving mulberry shoots instead of individual leaves. Rearers then collect them and place them in baskets of dry leaves allowing them to complete their cocoon spinning process. 95% of the world’s silk production is mulberry. Silk, the queen of textiles is made from natural fibers secreted by insects of different species. The third and final instar is the ‘blue egg’ stage when the larva excretes all the excreta and turns translucent and yellowish in color. Cultivation of Food-plants: Depending upon the size of the thread desired, the number of cocoons (usually 6 to 10) are taken. The young worms are fed tender leaves. ìb…©¥†i_pòbZO¢ÙªUŸ©_œF•DÎ^5ÁjS&†eòLøkP"ª;eå0î¾Ï>C¨«)Auax?x2ã‚GÎQÎWÌSƒúôØs˜±ÔB³ÙjA…¤Aå…v_MEßóñ÷G^‚¾xƒcÇ«šö¼:Z•-ôvÃ7`]ó1AŸ–x*¥ö?¿çO‚‰H¨. They cut the cocoons themselves or are taken out by hand. Oak tasar silkworm rearing technology J. TEMPERATE (OAK) TASAR – SILKWORM SEED PRODUCTION 1. Concerned about ethics behind a business? Mulberry silk weaving is one of them. Then there is the floor method where the silkworms are reared on a raised platform right on the floor itself. Once the threads are removed of sericin (de-gumming) and the threads are twisted, the raw silk becomes silk yarn which is then made into skeins or hanks. Shorea robusta, Roxb 4. At this stage, the larvae are taken and placed on trays called ‘chandriki’ where they will start forming into cocoons. In winter it can take up to 2 months. Silkworm rearing starts with silkworm egg incubation. Prior to rearing, disinfection of the rearing room was done with 2% Formalin solution. Like other larvae, muga silkworms eat voraciously, 1000 silkworms need one big tree or two medium-sized trees during their entire larval period. This is still a raw silk thread. The Chinese people knew the methods for cultivating silk and of preparing cloth from it for more than 2000 years. The experiment was consisted three different indoor rearing methods for rearing chawki larva. It is renewable, eco-friendly, and durable. In the method of rearing silkworm, the last three stages should be conducted by giving mulberry shoots instead of single leaves. Silk fabrics are unparalleled in luxury; they are the ultimate attractions of Haute-courtier. The skilled weavers can produce designs of any intricacy. As a natural fiber, silk needs no introduction.
