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, ...
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...
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...
HETEROSIS STUDIES ON INDIGENOUS BIVOLTINE SILKWORM HYBRIDS
MULTIPLE REARING AND FOOD DYNAMICS IN SILKWORM (Bombyx mori L.)
The present study entitled, Organic based nutrient management in mulberry and its impact on silkworm was conducted during spring season 2019 at Division of Sericulture, SKUAST-Jammu in order to know the effect of different organic manures alone and in combination with biofertilizer (Azospirillum) on growth and yield parameters of mulberry (var. China white), rearin...
