Silkworms and mulberry leaves placed on trays (Liang Kai's Sericulture c. 13th century) Silkworms were first domesticated in China more than 5,000 years ago. [28] [29] Pupae Silkworm cocoons weighed and sorted (Liang Kai's Sericulture) Silkworm breeding is aimed at the overall improvement of silkworms from a commercial point of view.

The silkworm Bombyx mori is fed on mulberry leaves cultivated in plantations. Silkworms are also found wild on forest trees, e.g Antheraea paphia which produces the tasar silk ( Tussah ). Antheraea paphia feeds on several trees such as Anogeissus latifolia , Terminalia tomentosa , T. arjuna ( Terminalia arjuna ), Lagerstroemia parviflora and ...
