Abstract: The natural silk yielded by sericigenous insects is one of the most important textile fibers. The natural silk has emerged as the most liked textile fiber in spite of heavy competition by the synthetic fibers. The domesticated silkworms contributed the bulk of global silk. Although bulk of the commercial silk is produced by the mulberry silkworm, Bombyx mori, the other silkworms commercially exploited for silk production are eri and muga. India is unique in producing the tasar silk.
Silkworms suffer from various diseases namely pebrine, virosis, bacteriosis and muscardine caused by microsporidia, cytoplasmic polyhedrosis virus, different types of bacteria and fungus respectively and loss due to these diseases is at considerable rate. In India, the extant of cocoon crop loss due to the silkworm diseases is nearly 40% (Sahay et al., 2000). Bacteriosis is caused by Gram negative and Gram positive bacteria. It is transmitted orally. Its impact is more pronounced in larval stage which affects cocoon productivity and quality along with 10-15 % crop loss. Poor leaf quality and poor feeding are predisposing factors of this disease. Rods and Cocci are observed from the body fluid of infected larvae.
