Bombyx mori the molecular identification of the first known pheromone, bombykol, which required extracts from 500,000 individuals, due to the very small quantities of pheromone produced by any individual worm. Currently, research is focusing on genetics of silkworms and the possibility of genetic engineering. Many hundreds of strains are maintained, and over 400 Mendelian mutations have been described. Another source suggests 1,000 inbred domesticated strains are kept worldwide. One useful development for the silk industry is silkworms that can feed on food other than mulberry leaves, including an artificial diet. Research on the genome also raises the possibility of genetically engineering silkworms

Kambei Mori Kambei Mori or , also known as Mōri Kambei Shigeyoshi , was a Japanese mathematician in the Edo period. Some 16th-century sources suggest that Mori studied in China, but such claims are inconclusive or rejected by historians. What is known with certainty is that he started a school in Kyoto and he wrote several influential and widely discussed books which dealt with arithmetic and the use of the abacus. One of his students was Yoshida Mitsuyoshi the author of "Jinkōki," which is
