A genus of silkworm MOTHS in the family Bombycidae of the order LEPIDOPTERA. The family contains a single species, Bombyx mori from the Greek for silkworm + mulberry tree (on which it feeds). A native of Asia, it is sometimes reared in this country. It has long been raised for its SILK and after centuries of domestication it probably does not exist in nature. It is used extensively in experimental GENETICS. (From Borror et al., An Introduction to the Study of Insects, 4th ed, p519)
A serine-rich sticky protein secreted by MOTHS. Generally, the term refers to silkworm silk gum protein secreted in the middle section of silk gland cells of SILKWORMS, Bombyx mori. Sericin acts as a cement and coating for the two fibroin filaments in a silk strand and is readily soluble in mild alkaline solution.
Arthropods of the class ARACHNIDA, order Araneae. Except for mites and ticks, spiders constitute the largest order of arachnids, with approximately 37,000 species having been described. The majority of spiders are harmless, although some species can be regarded as moderately harmful since their bites can lead to quite severe local symptoms.
