The temperate oak tasar silkworm, Antheraea proylei, is frequently infested with Antheraea proylei nucleopolyhedrovirus (AnprNPV) causing tiger band disease. This disease is one of the key factors that obstructs production and productivity of oak tasar sericulture. The current study aimed to investigate the pathogenicity of AnprNPV, its mode of transmission, and detection of AnprNPV in different tissues.

Bombyx mori densovirus 1 (BmDV1) is a pathogen that causes flacherie disease in mulberry silkworms (B. mori). The absolute resistance (non-susceptibility) to BmDV1 of certain silkworm strains is determined independently by two genes, nsd-1 and Nid-1.

The mulberry silkworm, (L.), is a model organism of lepidopteran insects with high economic importance. The viral diseases of the silkworm caused by Bombyx mori nucleopolyhedrovirus (BmNPV) and Bombyx mori bidensovirus (BmBDV) inflict huge economic losses and significantly impact the sericulture industry of India and other countries.

Article Synopsis
  • Mulberry is crucial for sericulture as silkworms feed on its leaves, but there are few genetic options for resistance to root-knot nematodes (RKN).
  • A study screened 415 mulberry accessions, identifying 21 as highly resistant and 48 as resistant, with the most resistant found in certain origins.
  • Eight accessions were highlighted as valuable genetic sources for breeding RKN-resistant mulberry plants, and molecular analysis confirmed that simple sequence repeat markers can effectively assess genetic diversity between resistant and susceptible mulberry strains.

Microorganisms play an important role in the growth and development of numerous insect species. The mulberry silkworm, Bombyx mori (Lepidoptera), harbors several bacteria in its midgut aiding the metabolic processes; however, the variability of bacterial spp. present in the midgut and their role(s) in the growth and development of the silkworm are poorly understood.

Mulberry (Morus spp.), being an economically important tree, is cultivated in China, India, Thailand, Brazil, Uzbekistan and other Countries across the globe, for its leaves to feed monophagous mulberry silkworm (Bombyx mori). The sustainability of silk industry is directly correlated with the production and continuous supply of high-quality mulberry leaves.

Bombyx mori nucleopolyhedrovirus (BmNPV) that infects the silkworm, B. mori, accounts for >50% of silk cocoon crop losses globally. We speculated that simultaneous targeting of several BmNPV essential genes in transgenic silkworm would elicit a stable defense against the virus.
