According to the person in charge of the company, traditional silkworm cocoons are generally white. In recent years, a small amount of colored cocoons have appeared because silkworms eat color feed. Since last year, the company and Zhejiang University have teamed up to transform the genetics of silkworms to produce genetically modified silkworms that can produce natural colors. At present, the market price of this new type of color silkworm is at least twice as high as that of the traditional silkworm cocoon.
