Sericulture, or silk farming, is the cultivation of silkworms to produce silk. Although there are several commercial species of silkworms, the caterpillar of the domestic silkmoth is the most widely used and intensively studied silkworm. This species of silkmoth is no longer found in the wild as they have been modified through selective ...
Silkworms are the larvae of silk moths. The silkworm is of particular economic value, being a primary producer of silk. The silkworm's preferred food are the leaves of white mulberry, though they may eat other species of mulberry, and even leaves of other plants like the Osage orange. Domestic silk moths are entirely dependent on humans for ...
The production of silk originated in China in the Neolithic period, although it would eventually reach other places of the world (Yangshao culture, 4th millennium BC). Silk production remained confined to China until the Silk Road opened at some point during the latter part of the 1st millennium BC, though China maintained its virtual monopoly over silk production for another thousand years.
Silkworms produce silk when undergoing larval to adult metamorphosis. Raspy crickets produce silk to form nests. Honeybee and bumblebee larvae produce silk to strengthen the wax cells in which they pupate. [1] Bulldog ants spin cocoons to protect themselves during pupation. [1] Weaver ants use silk to connect leaves together to make communal ...
French production of fresh silkworm cocoons. Though highly regarded for its quality, Italian silk cloth was very expensive, both due to the costs of the raw materials and the production process. The craftsmen in Italy proved unable to keep up with the needs of French fashions, which continuously demanded lighter and less expensive materials. [51]
Mature Silkworm before Spinning. Dragon silk is a material created by Kraig Biocraft Laboratories of Ann Arbor, Michigan from genetically modified silkworms to create body armor. Dragon silk combines the elasticity and strength of spider silk. It has the tensile strength as high as 1.79 gigapascals (as much as 37%) and the elasticity above 38% ...
The cocoons of eri silkworms are open-ended, meaning the grown larvae can leave via the opening. This has led to eri silk being termed "peace silk" or ahimsa silk as its production harms no living organisms. Mulberry silkworms, on the other hand, make a hole in the cocoon when emerging as moths, thus damaging the silk.
Bombyx is the genus of true silk moths or mulberry silk moths of the family Bombycidae, also known as silkworms, which are the larvae or caterpillars of silk moths. The genus was erected as a subgenus [ 2 ] by Carl Linnaeus in his 10th edition of Systema Naturae (1758).
