Som (Persaea bombycina Kost) and Soalu (Litsea monopetela (Roxb.) Pers are the primary food plants of muga silkworm (Choudhury, 1970). Som leaves improves silk producing ability where as, soalu leaves enhances egg laying capacity of muga silkworm (Thangavelu, et. al. 1986). Som plants grow up to an altitude of about 600 metres while Sualu up to 1000 metres above  sea level. The nutrition of silkworm entirely depends upon the quality of leaves.

This unusual colour and strong nature of the thread produced from the cocoon of this silkworm are the two important features for which this silkworm is termed unique. Muga silkworm is multivoltine in nature, with six broods per year, including two crops each of pre-seed, seed and commercial. ‘Chotua’ (reared during March-April) and ‘Bhodia’ (reared during August-September) are seed crops, ‘Jethua’ (May-June) and ‘Kotia’ (October-November) are commercial crop while ‘Jarua’ (December-January) and ‘Aherua’ (June-July) are pre seed crops. Jethua and Kotia are the only crops used for commercial production while the rest of the crops are meant only for obtaining seeds for supplying and continuing rearing in favorable seasons. Antherea assama is confined to only Brahmaputra Valley of India in the world. The Primary Host plant of Muga silkworm is Som (Persea bombycina) and Soalu (Litsea polyantha). Accounting to the State Sericulture Department, the State has produced 114.56 MT Muga Raw Silk, during the year 2011-12 as against 113.28 MT Muga Raw Silk, produced in the State during the year 2010-11.
