The objective of the present study was to estimate the level of inbreeding coefficient during inbreeding of the pedigree of random mating and selected populations of two distinct races of mulberry silkworm, Bombyx mori (Lepidoptera: Bombycidae), in the silkworm germplasm. The six generation data of the two races, namely multivoltine Pure Mysore and bivoltine NB4D2, were studied for inbreeding d...

The activity of sericulture is declining due the reduction of mulberry production area in sericulture practicing countries lead to adverse effects on silkworm rearing and cocoon production. Screening for nutrigenetic traits in silkworm, Bombyx mori L. (Lepidoptera: Bombycidae) is an essential prerequisite for better understanding and development of nutritionally efficient breeds/hybrids, which ...

Composting and mixing organic inorganic materials are among the abilities of earthworms. The survival earthworms is influenced by several environmental factors, including media temperature, pH, moisture, texture, nutrient content. Shellfish shells underutilized waste that increasing in quantity as more people consume food from sea. This study aims to analyze productivity (Pheretima sp.) using a...

The aim of the study is identification bivoltine breeds suitable for regional abiotic stress conditions to achieve successful cocoon production.
 Study Design: In this regard present has been taken up with ten accessions (4 oval and 6 dumbbell) linked thermo tolerance SSR markers evaluated under different agroclimatic namely, (a) high temperature low humidity; (b) moderate humidity (c) hum...

Aim: The experiment was aimed at evaluating the effect of mulberry irrigated with treated sewage water on silkworms and cocoon production.
 Study Design: laid out in a Randomized Complete Block Design (RCBD) six treatments four replications.
 Place Duration Study: study conducted during Rabi 2019 pre-established V-1 garden Department Sericulture, University Agricultural Sciences, Gand...

In silkworm, prothoracicotropic hormone (PTTH), directly or indirectly controls silk production and spinning activity along with juvenile hormone (JH). An effort was made to exploit the potential of PTTH by indirectly activating silk gland for increasing silk productivity using short chain synthetic analogues of PTTH. The analogy in action was also established using PTTH extracted from the silk...

Five layers, i.e. floss, upper, middle, lower and pelade, exist in cocoon shell from outer to inner portion. An attempt has been made for assessment of microstructural characteristics eri silk fiber different layers cocoons. Wide angle x- ray diffraction revealed increase crystallinity as well degree orientation decrease crystal size besides lattice spacing remains at par floss pelade layers. S...

We have used the vectorised and parallelised magnetohydrodynamics code NIRVANA on the NEC SX-5 and the new SX-6 installation in parallel mode to simulate the interaction of jets with a galactic wind that might be typical for the star-bursting radio-galaxies of the early universe. The two simulations, one axisymmetric and one in 3D show that the jet pierces and destroys a thin and dense shell pr...

At the global level, special attention is paid to care of mulberry silkworm Bombyx mori L. in different climatic conditions, adaptation monovoltine breeds and hybrids ecological regions, production high-quality raw silk that meets requirements international standard 2A, 3A, 4A. being directed. Today, creating a new generation improving technological properties cocoons materials obtained from th...
