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

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

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.

Characterization of a Bombyx mori nucleopolyhedrovirus with Bmvp80 disruption

Virus Research, 2008
A BmNPV Bacmid with the Bmvp80 gene disrupted was constructed using the ET-recombination system in Escherichia coli to investigate the role of Bmvp80 during the baculovirus life cycle. Disruption of Bmvp80 resulted in single cell infection phenotype, whereas a rescue BmBacmid restored budded virus titers to wild type levels; however, the homologous ...

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.

Characterization of a nucleopolyhedrovirus of Epinotia granitalis (Lepidoptera: Tortricidae)

Journal of Invertebrate Pathology, 2007
A nucleopolyhedrovirus (NPV) from the cypress bark moth Epinotia granitalis Butler was partially characterized. Electron microscopy indicated that E. granitalis NPV (EpgrNPV) is a singly embedded nucleocapsid NPV with a relatively small polyhedron, ranging from 480 to 1100nm in diameter.

Virulence of a Nucleopolyhedrovirus to Neodiprion abietis (Hymenoptera: Diprionidae)

Journal of Economic Entomology, 2005
Different larval stages of balsam fir sawfly, Neodiprion abietis (Harris) (Hymenoptera: Diprionidae), were challenged by different concentrations of a nucleopolyhedrovirus in the laboratory to determine larval susceptibility to the virus and to test treatment effects of the virus on the sawfly survivors.

In vivo Production of Palpita vitrealis Nucleopolyhedrovirus

Arab Journal for Plant Protection
A Preliminary bioassay was conducted to determine the suitable larval instar of the olive leaf moth, Palpita vitrealis (Rossi) and the needed concentration of its homologous baculovirus Palpita viteralis nucleopolyhedrovirus (PaviNPV) for in vivo production.
