the co-inoculation of mulberry with phosphate solubilizing micro-organisms, nitrogen fixing bacteria and arbuscular mycorrhiza has influenced its macronutrient uptake through leaf. the data revealed that maximum nitrogen (484.12 kg /ha) , phosphorus (59.83 kg /ha) and potassium (244.61 kg/ha) uptake through leaf has taken place due to co-inoculation treatments as compared to the un inoculated t...

Cocoon related characteristics are economically important traits in the silkworm, Bombyx mori L. (Lepidoptera: Bombycidae). In this study a genetic linkage map was developed that identified QTL controlling the cocoon weight, cocoon shell weight, and cocoon shell percentage using 161 amplified fragment length polymorphism (AFLP) markers. Twenty PstI/TaqI primer combinations were employed to geno...

The economic and field performance of six Bombyx mori Linnaeus bivoltine strains were evaluated, namely ICIPE I, Chun-Lei X ZhengZhu (C X Z), QuiFeng X BaiYu (Q X B), Quingsong X Haoyoe (Q X H), Suju X Minghu (S X M) and 75xin X 7532 (75xin). Performance was based on larval, cocoon, pupa and shell weights, relationship of food consumption to larval weight, cocoon weight and shell weight. ICIPE ...

abstract more than %90 of natural silk in world is produced by means of mulberry silkworm (bombyx mori l.). therefore, it is important that we recognize and collect mulberry varieties which have high quantity and quality leaf performance. for this purpose, an experiment was conducted with five mulberry varieties (kenmochi, kairyonase, ichinose, shinichinose and local varieties) during two seaso...

African wild silkmoth, Gonometa postica Walker (Lepidoptera: Lasiocampidae), were reared indoors in order to examine the influence of rearing conditions on the structure and properties of silk cocoon shells and degummed fibers by using a scanning electron microscope, an Instron tensile tester, and a thermogravimetric analyzer. The cocoons reared indoors showed inferior quality in weight, length...

Silkworm cocoons are multi-layered composite structures comprised of high strength silk fiber and sericin, and their mechanical properties have been naturally selected to protect pupas during metamorphosis from various types of external attacks. The present study attempts to gain a comprehensive understanding of the mechanical properties of cocoon shell materials from wild silkworm species Anth...

A tropical climate prevails in most of the sericultural areas in India, where temperature increases during the summer lead to adverse effects on temperate bivoltine silkworm rearing and cause crop losses. Screening for thermotolerance in the silkworm, Bombyxmori L. (Lepidoptera: Bombycidae) is an essential prerequisite for the development of thermotolerant breeds/hybrids. In the current study, ...

The study on the “Effect of medicinal plant extract treatment on BmNPV polyhedra was undertaken in the Department of Sericulture UAS, GKVK, Bangalore-65. The treated polyhedral bodies with aqueous extracts of different medicinal plants viz., Adathoda vasica, Bougainvillea spectabilis, Phyllanthus niruri, Terminalia arjuna and Pongamia glabra administered to silkworm through mulberry leaves once...
