मुगा रेशम उत्पादकता में सुधार के लिए मुगा रेशम कीट के मेजबान पौधे (सोम) मे रोग व कीट प्रबंधन Sericulture is a viable cottage industry catering to the economically small and marginal families and hence this enterprise is well. accepted as an instrument for rural development. India has the unique distinction of being the only country in the world producing all the four varieties of natural silk viz. mulberry, tasar, eri and muga on a commercial scale. Among them, Antheraea assamensis, (Helfer) bears special significance for production of golden yellow muga silk which is endemic to North East India.  The muga silkworm is a multivoltine and polyphagous insect. 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. The food plants (Leaves) have significant effect on health and survival of silkworms. Better the quality of leaves greater the possibility of obtaining good quality cocoons. Diseases make the leaf unpalatable for the silkworms and cause...

सिल्‍क कीट के मेजबान पौधे अरण्डी की खेती  Northeastern region of India is rich in diversity of sericigenous insects and their host plants, out of which, four types namely Muga (Antheraea assamensis), Eri (Samia ricini), Oak tasar (Antheraea proylei) and Mulberry (Bombyx mori) silkworm have been commercially exploited for silk production.  The Eri silkworm is multivoltine and polyphagous sericin producing insects. Eri culture is a traditional agro-based small scale industry, primarily practiced to meet the partial need of warm clothing. Moreover, eri pupae are popular as delicacy among the tribal people of this region. Proximate analysis of pupa showed that it contains 55-60% protein, 25-30% lipid, 4.96% fiber, and other substances, e.g. hormones, trace elements and vitamins, thus indicating that it could be a good protein source-for various purposes (Sharma, 2010). Eri silkworm significantly contributes to the Indian commercial silk production which is mostly confined to the Brahmaputra valley of Assam in the tribal inhabited districts. Approximately, 1.3 lakh families with plantation area of 26000 hectares are involved in ericuluture in northeastern region of this country. Annual production of eri raw silk has significantly increased from 974 MT in 1999-2000 to 2460.50 MT in 2009-10. It is also practiced in few districts of the neighbouring states mainly Meghalaya, Nagaland, Manipur and Arunachal Pradesh....
