A new microsporidian isolated from Lamerin breed of Bombyx mori L.
Shabir A. Bhat, B. Nataraju, Ifat Bashir and K.A. Sahaf

Sericulture has been recognized as a women-friendly enterprise and over 53% of its workforce is women.  The author dwells upon various issues concerning women empowerment through sericulture. Microsporidian spores surviving within Lamerin breed of silkworm Bombyx mori L. are not able to cause much damage during production of silkworm seed and cocoon. This was isolated by centrifugation. Lamerinbreed isolated microsporidian (Lbms) shows clear differences when compared with standard strain Nosema bombycis in shape, polar filament number, germination percentage, larval/pupal mortality and rate of infection. The authors suggest further studies to establish its identification.

M.R. Nirmala and R. Sugun

In view of detrimental impact of use of chemicals and fertilizers for practicing sustainable agriculture as in case of India, the need for introduction, practice and promotion of organic farming becomes all the more important, meriting a balanced approach. The article discusses the various interventions like, generation of green bio-mass through intercultivation in mulberry, bio-control of pests and diseases in mulberry and silkworms besides biological inputs for silkworm rearing, that call for promotion, towards ensuring ecological balance and environmental safety.

Prospects of sericulture in Majuli - A river island of Brahmaputra
Ranuma Das, M. Sankar, M. Pamehgam, Palash Dutta and K. Giridhar

Availability of natural resources like silkworm varieties, food plants, skilled manpower and raw materials, in abundance in Majuli, a flood-prone district of Jorhat in Assam is the strength for development of sericulture in this region. Such development is possible by proper planning under district development plan and also sustained efforts in both pre and post-cocoon sectors ensuring backward and forward linkages and adoption of new sericulture technologies.

Of late, Information and Communication Technology has become an efficient tool to reach out to farmers with advisories on cultural practices as well as forewarning on disease and pest incidence. With ICTs taking front seat in India, Seriline, a mobile and web based system has been launched by the scientists of Central Silk Board, on a field trial basis in select pockets of Uttar Pradesh. It aims to integrate sericulture stakeholders and the research workers through the portal in order to improve productivity and also income from the activity. Procedures, strength, scalability and limitations of the system are discussed, here.

Tasar bivoltine rearing in Maharashtra - Yielding results
N.R. Singhvi 

Sericulture especially trivoltine tasar cultivation is an age-old practice by tribal communities, mainly in tribal areas of Maharashtra due to abundant availability of tasar food plants. In spite of good reelability and high silk content in Daba Bivoltine cocoons ,  its rearing had been sluggish largely due to farmers taking time to switch over. The preliminary work of rearing bivoltine Daba, taken up by the RTRS, Bhandara, of course, on a small scale, has started yielding results and now motivated the farmers to take it up. Presented here is a journey from the conservative approach to a land of promise in Maharashtra.

Silkworm pupal oil: A novel source of Omega-3 fatty acids 
Venkatesh Kumar R., Param Dev and Yashwant Kumar

The length of telomeres in chromosomes becomes reduced as the age grows. Omega-3-fatty acids which can not be synthesized by human body, however, can be obtained from fish oil, seafood, flax seed oil, soyabean oil and some other plant products etc., which may attenuate shortening of telomeres. Both the mulberry and non-mulberry silkworm pupae oil is a good source of Omega-3 fatty acids, which reduces the risk of cancer and cardiovascular diseases etc. Details.
