Tracing of Evolution in Silkworm, Bombyx mori L., on the Basis of Molecular Studies



Pure Mysore and Nistari are known oldest races of India. Both are multivoltine races which produce colored cocoons. The origin of these races is obscure. Pure Mysore was supposed to have originated from the race that Mysore King Tippu Sultan brought from China in 1875 and established in Karnataka State. Nistari is the well-known race also believed to have brought from China and established in West Bengal area. However, the wild sericigenous species of Bombyx, Theophila, and Ocinara are naturally distributed in the Himalayan ranges of Indo-China range and also in the Andaman Islands in India, besides Jawa, Sumatra, Borneo, and Malay Peninsula (Barlow, An introduction to the moths of South East Asia, 1982). Apart from these, there are wild relatives of silkworm, B. mandarina, which have been collected from Kedarnath. It is believed that the silkworm, Bombyx mori L., has evolved from B. mandarina in China and spread across the globe. There are many theories about the pattern of silkworm evolution and spread. In this article, the theories are discussed on the molecular basis.
