The incidence of various insect pests affects both quality as well as the quantity of mulberry leaves which in turn has a direct bearing on the quality of silk produced by the mulberry silkworm. In the plethora of different insect pests affecting mulberry leaves, mulberry leaf roller, Diaphania pulverulentalis (Hampson) is a serious one. In line with this, the pres...
The present investigation entitled “Cataloguing of some mulberry varieties and their bioassay studies” was carried out at Division of Sericulture, SKUAST-J, Udheywalla, Jammu to evaluate the best mulberry variety suitable for growth and economic characters of cocoons produced by the silkworm Bombyx mori L. Seven different mulberry varieties viz. NS-1, NS-2, NS-3, ...
Nucleopolyhedrosis viruses (NPVs) are well-thought-out lethal bio-pesticides to managethe Spilosomaobliqua and are found naturally in S.obliqua(SoNPV). They are often claimed to be species-specific and are expected to show less or no cross infectivity to other insect species of the same order, thus making them ideal candidates as biopesticides against certain insec...
Disinfection and hygiene are an integral part of silkworm, Bombyx mori rearing and assumes a significant part in the termination of pathogenic microorganisms. Therefore, the powders of different herbal plant parts were developed by SKUAST-J during the study and were compared with the standard (Vijetha) as well as control. Although, all the three formulations proved...
DEVELOPMENT AND EVALUATION OF DOUBLE HYBRID CROSSES OF SILKWORM (Bombyx mori L.)
One of the most important factors determining the larval and cocoon characters of silkworm, Bombyx mori, is the provision of space to the worms during rearing, especially during the 5th instar, when the space requirement of the wormsis maximum. Limitation of space or crowding greatly affects the physiology of worms influencing the cocoon production besides leading ...
The present investigation entitled “Effect of population density on quality cocoon production” was carried out at Division of Sericulture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Udheywalla, Jammu and Kashmir. Larval population has a great impact on biology and physiology of insects including silkworm Bombyx mori L. Experiment wa...
Sericulture is an agro-based industry, which suits to rural-based farmers, entrepreneurs, and artisans and require low investment. It has high potential for higher returnsand play vital role in improvement of rural economy in India. The present investigation entitled “Evaluation of factors influencing cocoon productivity in Jammu region” was conducted in three dist...
The present investigation entitled, “EVALUATION OF PROMISING BIVOLTINE HYBRIDS OF SILKWORM,Bombyx mori L.” was carried out at Division of Sericulture SKUAST-Jammu during autumn-2020. Twelve bivoltine silkworm hybrids viz., U-8×PO1, ND3×PO1, PO1×U-8, U-3×U-1, JD6×U-6, U-4×U-6, PO3×ND5, U-6×ND3, ND3×NSP, ND2×NSP, SH6×NB4D2 and FC1×FC2 were selected for the study. The...
The present investigation entitled “Expression of heterosis in relation to food utilization and conversion in silkworm hybrids” was carried out at Division of Sericulture, SKUAST-J, at Udheywalla during spring 2015 and 2016. The experiment was laid out in completely randomized block design with nine treatments, one control and three replications. Data on thirteen c...
The sericin is a unique protein that possesses promising attributes viz., antioxidant activity, antimicrobial activity, easy absorption and release of moisture, coagulant activity, chemo-protection and protection of solar ultraviolet radiations (UV). In this investigation, an attempt was made to recover sericin from waste cocoons following the standardized protoco...
The present study entitled as “Fortification of mulberry leaves with different proteins and its effect on silkworm, Bombyx mori L.” was carried out at Division of Sericulture, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Chatha, during 2021-2022. To optimize the concentrations of proteins, eighteen concentrations of different proteins...
