Muga silkworms are mostly wild unlike the mulberry silkworm, which is completely domesticated. Due to the high incidence of disease and natural enemies, and variations in climatic conditions, the production of muga silk has recently declined dramatically.

The silkworm is generally reared outdoor and is thus prone to vari-ous infections caused by microorgan-isms2. Muga silkworm (Antheraea assamensis Helfer) is endemic to Assam and adjoining areas in North-Eastern India, and naturally produces golden silk. These silkworms feed on the leaves of Som and Soalu plants and the silk produced from them is known for its glossy texture and durability. It is unique in being transmitted to offspring by transovarial/ transovum means from other moths. The muga silkworm rearing is conducted throughout the year (six times / year) on som and soalu plantations. of muga silk. During day time and night time, some predator attacks on 3rd to 4th instar of muga silkworm. Thus, from the present study it has been observed that, by conducting indoor rearing of muga silkworm for first two instars it is possible to reduce early instar loss of muga silkworm which is reported to be more than 30% [8 8. Several works have been done on nutritional values of Muga and Eri host plants through biochem-ical analysis for improving the diet of the silkworm.

One tree can be utilized for two rearing in a year alternately during spring and autumn, thus one full grown tree can yield 1000 cocoons in a year and 5 trees are required to produce 5000 cocoons which yield one kg. Large-scale production of muga silk is a daunting task due to insufficient yield of seed. �����_$y�K�\�����;w��dLz���#�gI��K�S["��7oָ��a��ׂ=z���&zf�Q+}��ݯh�>k�Ʊ�����KWV�ZR��E�̷lsH�a�-��|�!���V�;%�.��>uhCڇ� ������ ����P�R�R�_ �|����Y��bƳS��6����[�q#`P:L��b;��R�:�����f| &n݇b����}B��x��ބs%����?j��vS��f�lDjLjT���,8G�ȎZ>���S-D�Ms��=l�X����믅W�;Y|W�a}b0`�7��#�|[qI�T����1QBe����C����RP6��ٽ�,��0 �!���K�����B� Muga silk, which is mainly produced by the Garo community of Assam, is obtained from semi-domesticated multivoltine silkworm, Antheraea Assamensis.
