What is the scientific name of the moth responsible for most commercial silk production?

• A. Bombyx mandarina
• B. Bombyx mori
• C. Antheraea pernyi
• D. Samia ricini

Answer: (B)

The main idea here is identifying the moth species that has been domesticated and bred specifically for producing silk on a large scale. The moth responsible for most commercial silk production is Bombyx mori. This domesticated silkworm has been cultured for thousands of years for its ability to spin long, uniform silk cocoons and for traits that make farming practical, such as a calm temperament and high silk yield. The silk we trade commercially comes almost entirely from its cocoons, which are processed to obtain raw silk fiber. Bombyx mandarina is the wild ancestor of Bombyx mori, but it is not the source of the bulk silk used in industry. Antheraea pernyi produces tussar silk, and Samia ricini produces eri silk—both are other types of silk with different fibers and commercial scales, not the dominant silk in global production.
