BACKGROUND The silkworm, Bombyx mori, is an important insect in the textile industry and its pupa are used in Chinese cuisine and traditional Chinese medicine. The silk, urine and dander of silkworms is often the cause of allergies in sericulture workers and the pupa has been found to be a food allergen in China. Recent studies have focused on reporting cases of silkworm allergies, but only a f...

The carotenoid-binding protein (CBP) of the domesticated silkworm, Bombyx mori, a major determinant of cocoon color, is likely to have been substantially influenced by domestication of this species. We analyzed the structure of the CBP gene in multiple strains of B. mori, in multiple individuals of the wild silkworm, B. mandarina (the putative wild ancestor of B. mori), and in a number of other...

Alphabaculovirus is an entomopathogenic virus genus that infects Bombyx mori, which is known as the Bombyx mori multiple nucleopolyedrovirus (BmMNPV). This virus is polyorganotrophic, and a series of tissues are known as targets; however, there is currently no information regarding infection in the pylorus, the segment of the hindgut that is present in the midgut transition and is responsible f...

At the late stage of infection, a markedly enhanced locomotion behavior of infected larvae is observed (Goulson 1997), which is followed by a dramatic degradation of the host cadaver. The Bombyx mori NPV (BmNPV), one of the wellcharacterized baculoviruses, is a virus specifically pathogenic for t...

The present study deals with the oral supplementation with (50, 100 and 150 ?g/ml) synergetic effect of potassium and magnesium chloride on the fat body glycogen, protein, total lipids and haemolymph trehalose, protein of fifth instar larvae of Bombyx mori L (Lepidoptera: Bombycidae). The observed parameters significantly increased in all the treated groups when compared with those of the corre...

Bombyx mori L. (Lepidoptera: Bombycidae) nucleopolyhedrovirus (BmNPV) is a highly pathogenic virus in the sericultural industry, often causing severe damage leading to large economic losses. The immune mechanisms of B. mori against this virus remain obscure. Previous studies had demonstrated Bmlipase-1, BmNox and Bmserine protease-2 showing antiviral activity in vitro, but data on the transcrip...

Bombyx mori is an insect whose cocoon is used in the sericulture industry, which is an important activity in parts of southern Brazil. When parasitized by Bombyx mori nucleopolyhedrovirus (BmNPV) of the genus Alphabaculovirus (alphaBV), it develops nuclear polyhedrosis disease. In Brazil, an alphaBV was isolated from larvae of B. mori and various target tissues were identified. However, how thi...

Two glutathione S-transferase (GST) cDNAs, GSTD2 and GSTS2, were cloned from the silkworm Bombyx mori. The B. mori GSTD2 (BmGSTD2) gene spans 4371 bp and consists of four introns and five exons that encode 222 amino acid residues. The deduced amino acid sequence of BmGSTD2 showed 58% protein sequence identity to the Delta-class GST of Maduca sexta. The B. mori GSTS2 (BmGSTS2) gene spans 3470 bp...
