The experiments reported here were conducted to investigate the effect of selection on three quantitative traits, namely cocoon weight, cocoon shell weight, and cocoon shell percentage, during four generations by rearing six pure breeds of domesticated silkworm, Bombyx mori L. (Lepidoptera: Bombycidae) of Chinese and Japanese origin compared with random unselected groups as controls. All stages...

Oral supplementation with 50, 100 and 150 μg/ml arginine to the silkworm larvae resulted in a significant increase in the larval weight, silkgland weight in only 150 μg/ml, cocooning percentage in all the fed groups, female cocoon weight, cocoon shell weight, cocoon shell ratio, male cocoon weight, cocoon shell weight and shell ratio is increased in all the treated groups, filament length were ...

The Bag-shelter moth Ochrogaster lunifer (Lepidoptera: Notodontidae: Thaumetopoeinae) is an endemic species of medical and veterinary importance that occurs throughout Australia. gregarious variable with four phylogenetic clades recently identified. One clade comprises trunk-nesters restricted to one host: the Moreton Bay Ash, Corymbia tessellaris (Myrtaceae). Here, we describe aspects biology ...

topical application with 100, 200 and 300 ng/ml phytohormone salicyclic acid on commercial traits was analysed in bivoltine csr2, csr4 and csr2xcsr4 crossbreed races of the silkworm, bombyx mori l. the results showed that there was significant increase in larval weight female cocoon weight, male cocoon shell weight, and hatching percentage with 100 and 200 ng/ml, silkgland weight, female cocoon...

Maharashtra contributes paltry 0.76 per cent of the total production tasar silk in country, with 23 MT but state is found to be dwindling which might due gaps knowledge and adoption improved silkworm rearing technologies. Therefore, present investigation was undertaken assess technologies constraints faced by farmers adopting recommended The study conducted Bhandara, Gondia Gadchiroli districts...

Abstract Several cultural features found by archaeologists at the First Emperor of Qin's necropolis did not have roots in East Asian cultures but were inspired exchange with civilizations West Asia along various “Silk Roads.” Examples considered this article include terracotta figures soldiers and horses, long-pole acrobatics, terraced architecture for tombs, bronze chariots, bar-shaped bricks,...

Fibroin is normally composed of one H chain (350 kd) and one L chain (25 kd) which are connected by disulfide bond(s). However, the small amount of fibroin secreted into the lumen of the posterior silk gland of the Nd(2) (naked pupa) mutant does not contain L chain, although L chain mRNA is present and L chain is synthesized in the posterior silk gland cells of the mutant. In a hybrid silkworm,...

Intestinal obstruction is a fairly common surgical emergency that usually occurs due to herniae, adhesions, or bands. Rarely, uncommon causes such as an abdominal cocoon are encountered, where part or all of the small intestine is encased within a thin membrane. We report one such case of abdominal cocoon, in whom, further encasement of the distal ileum was seen within a separate membrane.
