Sericulture
Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, ''Bombyx mori'' (the caterpillar of the domestic silkmoth) is the most widely used and intensively studied silkworm. Silk was believed to have first been produced in China as early as the Neolithic Period. Sericulture has become an important cottage industry in countries such as Brazil, China, France, India, Italy, Japan, Korea, and Russia. Today, China and India are the two main producers, with more than 60% of the world's annual production. History According to Confucian text, the discovery of silk production dates to about 2700 BC, although archaeological records point to silk cultivation as early as the Yangshao period (5000–3000 BC). In 1977, a piece of ceramic created 5400–5500 years ago and designed to look like a silkworm was discovered in Nancun, Hebei, providing the earliest known evidence of sericulture. Also, by careful a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silk
Silk is a natural protein fiber, some forms of which can be woven into textiles. The protein fiber of silk is composed mainly of fibroin and is produced by certain insect larvae to form cocoons. The best-known silk is obtained from the cocoons of the larvae of the mulberry silkworm ''Bombyx mori'' reared in captivity (sericulture). The shimmering appearance of silk is due to the triangular prism-like structure of the silk fibre, which allows silk cloth to refract incoming light at different angles, thus producing different colors. Silk is produced by several insects; but, generally, only the silk of moth caterpillars has been used for textile manufacturing. There has been some research into other types of silk, which differ at the molecular level. Silk is mainly produced by the larvae of insects undergoing complete metamorphosis, but some insects, such as webspinners and raspy crickets, produce silk throughout their lives. Silk production also occurs in hymenoptera ( bee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Silkworm
The domestic silk moth (''Bombyx mori''), is an insect from the moth family Bombycidae. It is the closest relative of ''Bombyx mandarina'', the wild silk moth. The silkworm is the larva or caterpillar of a silk moth. It is an economically important insect, being a primary producer of silk. A silkworm's preferred food are white mulberry leaves, though they may eat other mulberry species and even the osage orange. Domestic silk moths are entirely dependent on humans for reproduction, as a result of millennia of selective breeding. Wild silk moths (other species of ''Bombyx'') are not as commercially viable in the production of silk. Sericulture, the practice of breeding silkworms for the production of raw silk, has been under way for at least 5,000 years in China, whence it spread to India, Korea, Nepal, Japan, and the West. The domestic silk moth was domesticated from the wild silk moth ''Bombyx mandarina'', which has a range from northern India to northern China, Korea, Japan ...

Morus (plant)
''Morus'', a genus of flowering plants in the family Moraceae, consists of diverse species of deciduous trees commonly known as mulberries, growing wild and under cultivation in many temperate world regions. Generally, the genus has 64 identified species, three of which are well-known and are ostensibly named for the fruit color of the best-known cultivar: white, red, and black mulberry (''Morus alba'', '' M. rubra'', and '' M. nigra'', respectively), with numerous cultivars. ''M. alba'' is native to South Asia, but is widely distributed across Europe, Southern Africa, South America, and North America. ''M. alba'' is also the species most preferred by the silkworm, and is regarded as an invasive species in Brazil and the United States. The closely related genus ''Broussonetia'' is also commonly known as mulberry, notably the paper mulberry (''Broussonetia papyrifera''). Description Mulberries are fast-growing when young, and can grow to tall. The leaves ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yangshao
The Yangshao culture (仰韶文化, pinyin: Yǎngsháo wénhuà) was a Neolithic culture that existed extensively along the middle reaches of the Yellow River in China from around 5000 BC to 3000 BC. The culture is named after the Yangshao site, the first excavated site of this culture, which was discovered in 1921 in Yangshao town, Mianchi County, Sanmenxia, western Henan Province by the Swedish geologist Johan Gunnar Andersson (1874–1960). The culture flourished mainly in the provinces of Henan, Shaanxi and Shanxi. Recent research indicates a common origin of the Sino-Tibetan languages with the Cishan, Yangshao and/or the Majiayao cultures. Economy Subsistence The main food of the Yangshao people was millet, with some sites using foxtail millet and others proso millet, though some evidence of rice has been found. The exact nature of Yangshao agriculture, small-scale slash-and-burn cultivation versus intensive agriculture in permanent fields, is currently a matter ...

Kingdom Of Khotan
The Kingdom of Khotan was an ancient Buddhist Saka kingdom located on the branch of the Silk Road that ran along the southern edge of the Taklamakan Desert in the Tarim Basin (modern Xinjiang, China). The ancient capital was originally sited to the west of modern-day Hotan ( zh, c=和田) at Yotkan (Chinese: 约特干; pinyin: Yuētègàn). From the Han dynasty until at least the Tang dynasty it was known in Chinese as Yutian ( zh, t=于闐, , or ). This largely Buddhist kingdom existed for over a thousand years until it was conquered by the Muslim Kara-Khanid Khanate in 1006, during the Islamicisation and Turkicisation of Xinjiang. Built on an oasis, Khotan's mulberry groves allowed the production and export of silk and carpets, in addition to the city's other major products such as its famous nephrite jade and pottery. Despite being a significant city on the silk road as well as a notable source of jade for ancient China, Khotan itself is relatively small – the circumference ...

Byzantine Silk
Byzantine silk is silk woven in the Byzantine Empire (Byzantium) from about the fourth century until the Fall of Constantinople in 1453. The Byzantine capital of Constantinople was the first significant silk-weaving center in Europe. Silk was one of the most important commodities in the Byzantine economy, used by the state both as a means of payment and of diplomacy.Laiou, Angeliki.Exchange and Trade". In Laiou (2002), p. 703 Raw silk was bought from China and made up into fine fabrics that commanded high prices throughout the world. Later, silkworms were smuggled into the Empire and the overland silk trade gradually became less important. After the reign of Justinian I, the manufacture and sale of silk became an imperial monopoly, only processed in imperial factories, and sold to authorized buyers. Byzantine silks are significant for their brilliant colours, use of gold thread, and intricate designs that approach the pictorial complexity of embroidery in loom-woven fabric.Scho ...

Smuggling Of Silkworm Eggs Into The Byzantine Empire
In the mid-6th century CE, two monks, with the support of the Byzantine emperor Justinian I, acquired and smuggled living silkworms into the Byzantine Empire, which led to the establishment of an indigenous Byzantine silk industry that long held a silk monopoly in Europe. Background Silk, which was first produced sometime during the third millennium BCE by the Chinese and/or Indus Valley Civilisation, was a valuable trade commodity along the Silk Road. By the first century CE, there was a steady flow of silk into the Roman Empire. With the rise of the Sassanid Empire and the subsequent Roman–Persian Wars, importing silk to Europe became increasingly difficult and expensive. The Persians strictly controlled trade in their territory and would suspend trade in times of war. Consequently, the Byzantine Emperor Justinian I tried creating alternative trade routes to Sogdiana, which at the time had become a major silk-producing centre:Clare, Israel (1906), Library of Universal Histor ...
