In order to open Eri silk in its original, fluffy form, it is either boiled with soap water or through scouring (cleaning) it in a large tank through the process of hydro-extraction. Phylosamia ricini, the Eri silkworm (Lepidoptera: Saturnidae), which feeds on castor (Ricinus communis) is raised in Assam, Madhya Pradesh, Rajasthan and Orissa commercially. It is most famous for silk drapes and silk saris remain the most significant output of Eri Silk. Eri silk is a popular silk item made from the Samia Cynthia Ricini caterpillar. Resultantly, the eri cocoons are open-mouthed and are spun. The eri silkworm is easier to keep than the mulberry silkworm (that produces common silk and feeds on mulberry leaves only) because it eats many types of leaves. Eri silkworms are reared indoor. It is the only domesticated silk produced in India, as the process doesn’t involve any killing of the silk worm, also naming Eri silk as ‘Ahimsa (ahinsa) silk or fabric of peace. cocoons to the Company, which then processes the cocoons and sells to other companies [4]. The eggs or ovoid, candid white. Eri silk is heavier compared to other types of silk. The silk is not reelable like Bombyx mori, the mulberry silkworm, so it is spun into a yarn which is both soft and durable.In their native lands, they are hand-fed mostly castor bean and tapioca leaves, but will also eat ailanthus and ligustrum. Castor (Ricinus communis) and Kes-seru (Heteropanax fragrans) are considered as the primary food plants where as Tapioca (Manihut utilisima), Jatropa (Jatropa curcus), papaya (Carica papaya), Borpat (Ailanthus Muga silkworm (Antheraea assama): It also belongs to the family saturnidae and semi-domesticated in nature. In sericulture, the eggs are collected and stored in a cold place when the food (mulberry leaves) are not abundant to feed the larvae. A coating of ‘sericin’ gum on the filament of the cocoon prevents it from opening with ease. Eri Silk is one of the purest forms of Silk that is a true and genuine product of the Samia cynthia ricini worm.

The Samia cynthia butterfly has a brown wing color in different shades of brown and has a beautiful purple stripe along the wings. Eri silkworms feed on castor plant, and mulberry silks feed mulberry leave in all sites. Eri silkworm (Samia ricinii) is a traditional source of food in northeast India, where it is grown primarily for silk and food uses.Nutrient analysis showed that the proximate composition of eri silkworm prepupae and pupae grown on either castor or tapioca were comparable and it was a good source of protein (16 g%), fat (8 g%) and minerals. Eri Silk. It is unwound from the cocoons and reeled into threads of commercial silk. They also have yellow spots and lines on the wings. It flies after its wings are completely dry. Manual cutting is inefficient, hence the ‘twin blade cutter’, modified for eri silk cutting is suitable. They grow very fast and undergo four moltings (changing the skin) to change into different instars. Eri silk is the product of the domesticated silkworm that feeds mainly on castor leaves. Ericulture is a household activity practiced mainly for protein rich pupae, a delicacy for the tribal. It is a natural fiber which is soft, shiny, strong and durable. The thread becomes wrapped around its body forming a pupal case known as the cocoon. Sushil Humagain The bulk of Eri Silk production gives Assam the name of Eri Silk state. In Nepal, two types of silkworm are reared for the commercial production of raw silk. The silk is extremely durable, but cannot be easily reeled off the cocoon and is thus spun like cotton or wool. Eri silkis also known as endi or errandi in India. Newborn silkworms must be fed young mulberry leaves because they are more tender than the older leaves; their mouths will not be able to eat the older leaves right away. A study was undertaken to evaluate different castor genotypes for the rearing performance of The Eri silk (also known as Endi or Errandi silk) is white or brick-red silk in color and is produced more in Assam and the adjacent North Eastern states. The male silkworms die after copulation and female silkworms die after laying eggs. The newly hatched caterpillar is 6mm long, brownish in color and moves in a characteristic looping manner. Rearing of eri silkworm: It is highly elastic and has long threads. One cocoon yields about 1000 feet of silk thread. Silkworms complete their life cycle in about 45 days. The eri silkworm feeds on various plants, but mainly castor bean leaves (Ricinus communis). The cocoons are open mouthed, tapering at one end and flat rounded at the open end. Eri silk combines the elegance of silk with the comfort of cotton and the warmth of wool. Typically, silk cocoons are boiled with the worm inside in order to produce one continuous silk filament from the cocoon. The native place of this species is Assam where it has now become a good source of cottage industry. It neither feeds nor moves and if permitted to live, it undergoes active metamorphosis and becomes an adult in about 10-12 days. into two groups of 24 animals each (12 males and 12 females) and fed the diet containing either 10% sunflower oil (Control) or eri silkworm oil (Experimental). Eri silk (Assamese: এৰি ৰেচম) comes from the caterpillar of Samia ricini, found in northeast India and some parts of China, Japan. In cold, the eggs don’t hatch for a long time and the increase in temperature causes them to hatch faster. In China, the Eri silkworms feed on a different host plant called Borkesseu, Ailanthus excelsa and the silk thus produced is called Ailanthus silk. The silkworms give the Eri Silk a dull yellow, gold like sheen. The body is divided into head, thorax and abdomen. Prominently found in the south Asian regions these Silk moths are predominantly found over the wild trees and shrubs of shorea Robusta and Terminalia. In the early spring, with the enough supply of food, the eggs are hatched inside the incubator at the temperature of 18-25. Castor (Ricinus communis Linn.) The primary food plant of this polyphagous insect is castor Ricinus communis L. Eri silkworms were successfully acclimatized in America and Europe, but could not take firm hold. Eri Silk has become the face of Indian Silk. Besides Bombyx Mori, this is the only silkworm species that is completely domesticated. This artificial silkworm feed was fed to the Eri-silkworm (philosamia cynthia ricini) in the following way: The feed was soaked in water (the volume of water was … Biologically named as Ailanthus Silk moth, this silkworm or known as a caterpillar is generally found in China and Japan. Pupa is completely inactive. This process is thus known as degumming. It is being bred on a massive industrial scale in Asia for silk production, and is also very populair with hobbyists that like to breed insects, and reptile owners that use them as convenient feeder animals. Silkworm farms and manufacturers that keep the worms have the option to feed their worms a special artificial mulberry diet. Also known as Endi or Errandi, Eri is a multivoltine silk spun from open-ended cocoons, unlike other varieties of silk. Eri silkworms that feed on caster leaves and seri silkworms that feed on mulberry leaves are two types of silkworms that are reared in Nepal. There is a subspecies, S. cynthia ricini in India and Thailand that feeds upon the leaves of castor bean, and is known for the production of eri silk, and is often referred to by the common name eri silkmoth. Eri silk is the product of the domesticated silkworm, Philosamia ricini that feeds mainly on castor leaves. The tassar silkworm resembles the Eri but the caterpillars feed upon Dalbergia, Shorea, and Terminalia, etc. The unique thing in Eri silk is the type of cocoon. It's fiber is not reeled.
