Abstract:
We planned to conduct this study with the main aim to develop bivoltine breeds for our tropical climatic conditions by using silkworm breeds with known genetic backgrounds (KA, NB18 and PM) in various hybrid combinations and incorporating them over generations, followed by backcrossing and adequate selection of different generations with the objective of profitability and productivity. The isolated Bivoltin lines (R1 and R2) were reared with their parental races at different times of the year to evaluate their stability in the expression of commercial traits. For the present breeding program,

Abstract:
The study was conducted in Kolar and Chikkaballapur districts of Karnataka state, to analyze the impact of adoption of bivoltine and multi × bivoltine hybrid silkworm rearing practices on cocoon yield and income of silkworm rearers. A sample of sixty bivoltine and multi × bivoltine hybrid silkworm rearing farmers were randomly selected from both the districts. The data was collected using a pre-tested interview schedule and the data was analyzed using suitable statistical tools. The results revealed that, more than two-fifth of the bivoltine hybrid silkworm rearers belonged to high (43.33%) ad

Abstract:
The growth of bivoltine silk production in eastern and north-eastern india lags behind drastically in comparison to southern states due to non-availability of suitable bivoltine hybrids. The major constraints in bivoltine popularization are adverse climatic conditions. to overcome this limitation and to continuously rear bivoltine hybrids in these harsh climatic conditions throughout the year, the present proposal aims to identify robust and abiotic stress tolerant bivoltine silkworm breeds through integrating conventional breeding (directional selection) for improved productivity and advanced

The sprouting behaviour of different 35 Mulberry varieties were taken during autumn 1999 and spring 2000 to screen out early sprouting varieties for introduction in the field for commercial exploitation. It was observed that Mandalya T-R8, TR10 and S146 are early sprouting varieties. These varieties take 13 to 14 days in spring and 7 to 10 days in autumn for sprouting. All exotic varieties were found exhibiting late sprouting characters. The sprouting in these varieties occurred only towards the second half of March and early April when temperature is comparatively higher for bivoltine rearing

 Study Design: Lepidopteran insect, Bombyx mori silkworm is more prone to crop losses due to hot climatic conditions during summer seasons. In order to produce bivoltine cocoons consistently throughout the year without affecting productivity during hot summer season, high temperature tolerant silkworm breeds are indispensable.

Potency of disinfectant was assessed for the parameters such as survivability, larval duration, physiological, chemo and bio-assay tests. It was revealed that, bivoltine (NB4D2) silkworms were highly susceptible to diseases compared to cross breeds (PMxNB4D2). In bivoltine silkworms, survivability was found to be 61.15% at 1.6% of Kavach, when dusted twice durin

Abstract:
Mulberry silk production in West Bengal and northeastern India, primarily involving bivoltine and multi-bi hybrid silkworm varieties, is a cornerstone of the sericulture industry. However, seasonal climatic variations, characterized by elevated temperatures and humidity, significantly affect cocoon quality, posing challenges to silk reeling efficiency and productivity. This study examines the influence of seasonal variations on the quality and reeling performance of bivoltine and multi-bi hybrid silk cocoons in these regions.

Abstract:
The mulberry silkworm, Bombyx mori L., 1758 (Lepidoptera: Bombycidae) is classified as univoltine, bivoltine, and polyvoltine based on the annual brood frequency. Voltinism in B. mori is characterized by the occurrence of embryonic diapause (facultative and obligatory diapause). Univoltine silkworms suited to cold and temperate regions lay diapausing eggs and polyvoltine silkworms suited to tropical regions lay non-diapausing eggs. In contrast, the occurrence of diapause in bivoltine silkworms is influenced by the environment. In addition to the difference in the occurrence of embryonic diapau

The directly developing summer generation is short-lived and time stressed, compared to the diapausing generation.
