Bombyx mori, commonly known as the domestic silk moth, is a moth species belonging to the family Bombycidae. It is the closest relative of Bombyx mandarina , the wild silk moth. Silkworms are the larvae of silk moths.
The best-known species is Bombyx mori , or domestic silk moth, native to northern China and domesticated for millennia. Another well-known species is Bombyx mandarina , also native to Asia. Taxonomy
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).
A silkworm, Bombyx mori, feeding on a mulberry tree. Mulberry leaves, particularly those of the white mulberry, are ecologically important as the sole food source of the silkworm (Bombyx mori, named after the mulberry genus Morus), the cocoon of which is used to make silk. [27] [28] The wild silk moth also eats mulberry.
Sericin is a protein created by Bombyx mori (silkworms) in the production of silk. [1] Silk is a fibre produced by the silkworm in production of its cocoon. It consists mainly of two proteins, fibroin and sericin. Silk consists of 70–80% fibroin and 20–30% sericin; fibroin being the structural center of the silk, and sericin being the gum ...
Bombyx mandarina and the domesticated Bombyx mori constitute two of the currently identified eight species of the genus Bombyx, the true or mulberry silk moths. The origin of the domestic silk moth is enigmatic. It has been suggested that it is the survivor of an extinct species that diverged from the ancestors of Bombyx mandarina millions of ...
In Bombyx mori, the biosynthesis is activated diurnally by pheromones through a neurohormone, the so-called pheromone biosynthesis-activating neuropeptide (PBAN). [40] The pheromone biosynthesis-activating neuropeptide (PBAN) is a neurohormone. The hormonal mechanisms of pheromone production vary considerably from species to species. [41]
(Bombyx mori) 56 This is for the species mulberry silkworm, B. mori (2n=56). Probably more than 99% of the world's commercial silk today come from this species. [91] Other silk producing moths, called non-mulberry silkworms, have various chromosome numbers. (e.g. Samia cynthia with 2n=25–28, [92] Antheraea pernyi with 2n=98. [93]) [94] 145
