Silkworm (Bombyx mori L.)
-
The present investigation was carried out at P. G. Department of Sericulture, Poonch campus, University of Jammu for isolation and identification of various diseases. Silkworm just like all other living organisms is susceptible to infection and diseases. Various pathogens including viruses (Nuclear Polyhydrosis, Cytoplasmic Polyhydrosis), bacteria (flacherie), fungi (muscardine) and protozoa (pebrine) cause various diseases to silkworm.

=Three types of artificial diets viz., Artificial diet1, Artificial diet2 and Artificial diet3 with different compositions were used for rearing Kolar Gold race of mulberry silkworm, Bombyx mori L. where the diets were fed up to initial three instars and the later two instars were reared on natural diet (untreated leaves). Formulated diets were compared with natural diet and the observations on growth parameters were recorded.

In the present study, susceptibility of the silkworm, Bombyx mori to the pathogens of mulberry pest Glyphodes pyloalis was ascertained. Silkworm, Bombyx mori inoculated with the pathogens isolated from G. pyloalis (Microsporidian and Nuclear Polyhedral Virus) showed high mortality at larval and pupal stages. Silkworms inoculated with Microsporidian showed mortality of 53.66% at larval stage whereas silkworms inoculated with Nuclear Polyhedral Virus showed mortality of 61.00% at larval stage.

Study on assessing the toxic effects of fungicides on silkworm (Bombyx mori L.) and also on cocoon and silk quality parameters revealed that carbendazim 50% WP and wettable sulphur 80% WP at 0.1% were found to have no toxic effect by showing zero larval mortality at three days after treatment. The larval weight and larval length of 29.33 g and 5.73 cm respectively in carbendazim 50% WP and 29.10 g and 5.42 cm) in wettable sulphur 80% WP was found to be higher than other fungicidal treatments.

The study revealed that, application of seriwaste bio-digester effluent to mulberry along with other organic manures increased the rearing and cocoon parameters providing all the essential nutrients for mulberry growth compared to application of sole inorganic fertilizers and in turn it contributed for quality cocoon production. Utilization of sericulture waste generated during mulberry cultivation and silkworm rearing leads to generate additional income, entrepreneurship development in sericulture and value addition in turn contributing to achieve sustainability in sericulture.

The principle of efficient use of available system for quality improvement is tried to utilize in the present study. The present attempt was undertaken to study the influence of acetone solution of Ferruginol, a natural phenol and a meroterpene compound, on the cocoon characters and silk filament parameters of silk worm Bombyx mori (L.) (Race: PM x CSR2). Three concentrations (5ppm; 10ppm and 20ppm) of Ferruginol were prepared.

The mulberry silkworm, Bombyx mori L is a Lepidopteran insect, life cycle of which include: Egg, Larval Instars, Pupa within silky cocoon and adult moth. It is purely domesticated insect since long, which make it a quite delicate venture, easily susceptible to viral and other diseases. The viral diseases are difficult to manage due to a very short life cycle of silkworm. One of the most effective solutions is a timely detection of such infection so that to stop spread of the disease.

The silk fiber of cocoons of silkworms of both the families consists of two major proteins, fibroin and sericin. The fibrion forms central core and sericin forms envelop. Fibroin and sericin, of mulberry silkworm, Bombyx mori deserve appreciable physioc-chemical properties and therefore, they are now recognized as excellent biomaterials in the field of tissue engineering, biotechnology and therapy. Sericin contributes about 20-30 per cent of total cocoon weight. It is characterized by its high content of serine and 18 amino acids, including essential amino acids.
