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
Nicolas Mori programmes were headed by the grim device of a death's head and the legend Memento Mori. As a performer 'Mori's attitude had the grace of manly confidence. His bow arm was bold, free, and commanding, and the tone he produced was eminently firm, full, and impressive. His execution was alike marked by abundant force and fire, by extraordinary precision and prodigious facility, but lacked niceties of finish and the graces and delicacies of expression' (Quarterly Mag. Music, iii. 323). He left behind him a son, Francis Mori (1820-1873), the composer of a cantata, entitled 'Fridolin;' an operetta, with words by
