INTRODUCTION Since the genus Rhynchosciara belongs, like Chironomus, to the suborder Nematocera it will be very interesting to see if the formation of its salivary secretion proteins is similar to that of Chironomus secretion or to Bombyx silk biosynthesis . Moreover, this work will be of importance for a better understanding of the hemolymph protein function and will provide a basis for improv...

Sericulture or silk farming is the rearing of silkworms for the production of raw silk. The mulberry silkworm, Bombyx mori, is a domesticated and monophagous insect which feeds only on the leaves of mulberry for its nutrition. Thiadiazoles are heterocyclic compounds containing oxygen and nitrogen. 1, 3, 4, thiadiazoles are extensively studied and are known to play diverse biological activities....

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...

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...

This study investigates the influence of microclimate factors on uniformity silk thickness and explores application a mechatronic system for optimal control maintenance. As environmental conditions vary daily seasonal basis, managing temperature relative humidity becomes crucial consistent cocoon production. The review delves into significant role in growth development silkworms, highlighting p...

Silk cocoon membrane (SCM), a solid matrix of protein fiber, responds to light, heat and moisture and converts these energies to electrical signals. Essentially it exhibits photo-electric and thermo-electric properties; making it a natural electro-magnetic sensor, which may influence the pupal development. This raises the question: 'is it only electricity?', or 'it also posses some kind of magn...

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...

This study used the larval tissues and colored cocoons of silkworms, Bombyx mori L. (Lepidoptera: Bombycidae), that were fed leaves of cultivated mulberry, Husang 32, as experimental material. The pigment composition and content in colored cocoons and tissues of the 5th instar larvae and the mulberry leaves were rapidly detected using organic solvent extraction and reverse phase high-performanc...

Silk cocoon membrane (SCM) is an insect engineered structure. We studied the electrical properties of mulberry (Bombyx mori) and non-mulberry (Tussar, Antheraea mylitta) SCM. When dry, SCM behaves like an insulator. On absorbing moisture, it generates electrical current, which is modulated by temperature. The current flowing across the SCM is possibly ionic and protonic in nature. We exploited ...
