Mulberry silk weaving is one of them. Once the silkworms have completed their larval cycles they turn into chrysalises or pupae, wrapping themselves up with fine threads in cocoons. Rearing of eri silkworm: Disease-free seed cocoons are obtained from grainages or agencies and reared fully indoors. Success has been achieved in this regard to some extent. Pre-cocoon Segment: a) Laying (egg) preparation. Leaves should not be wet and younger worms need more tender leaves. Silk is natural, health-friendly, and eco-friendly. Cultivation of Food-plants: As soon as the worms hatch they begin feeding. Munis Entomology & Zoology, 14 (2): 629-633] ABSTRACT: The rearing performance of sixteen hybrid combinations were evaluated to find out the superior hybrids. Sericulture is an art of rearing silkworm for the production of cocoons which is the raw material for the production of silk. Besides more than two dozens of secondary food plants. This method is the most economical method of rearing, as it helps to save about 40% of rearing labour. Terminalia tomentosa, W & A (Fig. Mulberry leaves are harvested and chopped into fine pieces to feed the larvae. In later stages, the leaves are adjusted according to the maturity of the worms. Egg incubation system.  Â. Mulberry silkworm rearing needs space, equipment, the right temperature, and stable humidity conditions. Before the pupae emerge out of the cocoon and metamorphose into a silk moth, they are stifled by boiling or heating to prevent them from cutting the cocoons. Lagerstroemia parviflora, Roxb.

Rearing of Silkworms: Life Cycle and other details on Silkworms. ], conducted indoor rearing of muga silkworm by cellular method and found that rearing in Soalu plants was suitable during different seasons for improvement in ERR, but female cocoon weight and fecundity were found significantly higher on ‘Som' plant. In India, the import demand for silk is so high and is the second largest producer after China. The rearing is done indoors where certain conditions are maintained. The rearers have their hands full all the time. The important reasons for low production are attributed to traditional method of silkworm rearing on tall trees ctcle natural habitat, which exposes the larvae to a number of predators, parasites and diseases apart from natural vagaries.

Only during the egg-laying process, rearing is done indoors on small sticks or sun grasses. The rearing room and equipment should be disinfected. Commercialization of Oak tasar silkworm, Antheraea proylei 2. Under these conditions eggs are expected to hatch within 10 - 12 days. c) Marketing of cocoons. Sericulture is the practice of rearing silkworms for the production of raw silk. Raising silkworms involves feeding the larvae with leaves from food plants that they like to eat. The glass bottles were disinfected with 0.04% Sodium hypochlorite (NaOCl) solution. Placed at the foot of the trees, the larvae then crawl up and start eating the tree leaves. They cut the cocoons themselves or are taken out by hand. In summer they remain in the pupa stage for nearly 3 weeks. The next process is weaving which follows in sequence when cocoons are processed further. Even today muga is the monopoly of Northeast India, particularly Assam and Meghalaya. In order to stabilize tasar silk production and increase income from tasar culture, tasar silkworm rearing methods need considerable improvement, as outdoor rearing of wild silkworm exposes the larvae to the vagaries of climatic conditions and also make them more vulnerable to pests and diseases. The first instar or the ‘pinhead stage’ occurs as soon as the egg hatches. Ensure disinfection two days before brushing of worms. It is great for winter clothing while remaining cool in the summer. worms, ii) rearing of silk worms, and iii) reeling and spinning of silk.

The moths are therefore killed before they could come out to obtain the maximum and continuous length of the thread. The harvesting process is called rearing. The other advantages of shoot rearing include the following list: During the remaining larval in stars the losses from diseases and pets … The weavers use mostly single-ply twisted yarn for the warp and single or double-ply twisted yarn for the weft. Since they are voracious eaters, larvae have to continually shed their skin as they grow bigger and bigger. The farmers, who practiced Tasar sericulture as a complementery source of income to agriculture, had slowly abandoned silkworm rearing. Then there is the floor method where the silkworms are reared on a raised platform right on the floor itself. At this stage, the threads are untwisted and still contains sericin, a protein that coats the thread. Package for Chawki (young age) silkworm rearing. 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. Post-cocoon Segment: a) Yarn production. This gives a patterned design to a plain weave, with an elegance of its own. b) Weaving of Fabric. d) Marketing of Yarn and Fabric. In winter it can take up to 2 months.

Typically, 300 … In the method of rearing silkworm, the last three stages should be conducted by giving mulberry shoots instead of single leaves. A technique of “controlled rearing” has been evolved by the Central Tasar Research Station, Ranchi. Silver is then extracted from the cocoons by unwinding or spinning the filaments, twisting them into threads and finally weaving the silk yarn into fabrics. Int.J.Curr.Microbiol.App.Sci (2017) 6(4): 2421-2425 2424 Table.2 Mortality rate of tasar silkworms due to various pest and disease on direct rearing method in host plants under block plantation and chawki methods Fig.1 Larva weight of tasar silkworm on direct rearing method in host plants under block plantation and chawki rearing methods When the larvae are fully matured they excrete their last excreta and began searching for a place to start the cocooning process. T. arjuna, W&A (Fig. Â. Rearing muga silkworms is fraught with problems like weather, temperature, predators such as birds, lizards, and disasters like forest fires and cyclones. Tasar Keet Oushad against silkworm diseases. Depending upon the size of the thread desired, the number of cocoons (usually 6 to 10) are taken.
