A nucleopolyhedrovirus from Uranotaenia sapphirina (Diptera: Culicidae)

Journal of Invertebrate Pathology, 2004
In this report we present data on biology, gross pathology, ultrastructure, and host range studies of a naturally occurring nucleopolyhedrovirus from the mosquito Uranotaenia sapphirina (UrsaNPV). Development of this virus was restricted to nuclei of epithelial cells in posterior midgut and distal gastric caecum.

Nucleopolyhedrovirus Interactions with Their Insect Hosts

1997
It is clear from this brief review that our understanding of the molecular cross-talk between insects and their baculovirus pathogens is still very limited. Studies in cell culture have taught us a great deal about the basic baculovirus molecular machinery and how it is regulated, and in many cases this information has been predictive of what occurs in

Phosphoenolpyruvate carboxykinase is involved in antiviral immunity against Bombyx mori nucleopolyhedrovirus

Developmental and Comparative Immunology, 2019
Phosphoenolpyruvate carboxykinase (PEPCK) has cytoplasmic isoform (PEPCK‐C) and a mitochondrial isoform (PEPCK‐M). PEPCK‐C plays an important role in gluconeogenesis, but the function of PEPCK‐M is largely unknown.

Enhancing the multiplication of nucleopolyhedrovirus in vitro by manipulation of the pH

Journal of Virological Methods, 2009
Insect nucleopolyhedroviruses (NPVs) are studied widely as agents for biological control, as expression vectors for the production of heterologous proteins, and as transduction vectors for gene therapy applications. Most of these applications rely on the existence of cell lines that allow in vitro multiplication of the virus. The influence of pH in the

Characterization of four isolates of Bombyx mori nucleopolyhedrovirus

Archives of Virology, 2000
Bombyx mori nucleopolyhedroviruses (BmNPVs), isolated from a sericultural Korean farm, were purified and characterized by their DNA restriction pattern, virus replication, polyhedra production and gene structures. The EcoR I and Sal I fragments showed similar overall patterns with minor difference but distinguishable patterns in each isolate. There was

Repeated Reversion of Resistance to Nucleopolyhedrovirus byAnticarsia gemmatalis

Journal of Invertebrate Pathology, 1998
A laboratory population of Anticarsia gemmatalis subjected to 80% mortality by the A. gemmatalis nucleopolyhedrovirus (AgNPV) developed a 5x resistance ratio (RR) within four generations. When exposure to AgNPV was discontinued, the resistant insects returned to their original level of susceptibility within three generations.

Bm65 is Essential for the Propagation of Bombyx mori Nucleopolyhedrovirus

Current Microbiology, 2012
Orf65 (Bm65) of Bombyx mori nucleopolyhedrovirus (BmNPV) is a highly conserved gene that encodes an unknown 104-amino acid protein. In the present study, we have shown the role of Bm65 in the baculovirus life cycle. 5'-RACE analysis showed that the transcription start site of Bm65 was 14 nucleotides upstream of the start codon ATG.

C-lysozyme contributes to antiviral immunity in Bombyx mori against nucleopolyhedrovirus infection.

Journal of insect physiology, 2018
Lysozymes is a ubiquitous immune effector that is widely distributed in both vertebrates and invertebrates. Previous reports have shown that lysozymes significantly inhibit viral infections in vertebrates.

Transcriptomic analysis of interactions between Hyphantria cunea larvae and nucleopolyhedrovirus.

Pest Management Science, 2018
BACKGROUND Hyphantria cunea is a destructive forest pest. To utilise H. cunea nucleopolyhedrovirus (HcNPV) for biological control, understanding insect-virus interactions is essential. RESULTS Four cDNA libraries were constructed from H.
