The silkworm, Bombyx mori, is used for sericulture and is one of the most economically important insects in the world (Fig. 1). The species of silkworm usually raised by sericulturists is B. mori (Lepidoptera: Bombycidae). A closely allied species is the mulberry wild silkworm, B. mandarina. Its morphology does not differ markedly that of from B. mori, and hybrids are highly fertile.

Along with Drosophila melanogaster, B. mori larvae have been used as a model for various biological studies for many years. These two insect species have greatly contributed to the progress of research in several scientific fields.
