Rapid Detection of Multiple Nucleopolyhedroviruses Using Polymerase Chain Reaction

Molecules and Cells, 2001
A technique using the polymerase chain reaction (PCR) was developed for detection of the nucleopolyhedrovirus (NPV) polyhedrin gene. The amino acid sequences of the polyhedrin gene were compared in twenty-six NPVs. A highly conserved DNA sequence within the coding region of the polyhedrin gene was targeted for amplification.

Diversity and biological activity of nucleopolyhedroviruses of the leafworm Spodoptera litura

, 2018
Increased resistance of emerging cotton leafworm Spodoptera litura in Pakistan and elsewhere to chemical insecticides calls for an alternative method of control. Isolates of nucleopolyhedrovirus (NPVs) of S. litura (SpltNPV) were collected from infected larvae in different ecological and geographic regions of Pakistan.

Molecular analysis of the p48 gene of Choristoneura fumiferana multicapsid nucleopolyhedroviruses CfMNPV and CfDEFNPV.

Journal of General Virology, 1999
Attempts were made to linearize the DNA of Choristoneura fumiferana (Cf) multicapsid nucleopolyhedrovirus (MNPV), in order to improve the efficiency of generation of recombinant viruses after transfection. A unique site for the restriction enzyme Sse83871 was found in ORF p48.

Synergism between the nucleopolyhedroviruses of Autographa californica and Trichoplusia ni.

Acta virologica, 2004
Previous observations on high virulence of Autographa californica multiple nucleopolyhedrovirus (AcMNPV) and Trichoplusia ni single nucleopolyhedrovirus (TnSNPV) acting together led us to test possible synergism between these two nucleopolyhedroviruses (NPVs) on cabbage looper larvae.

Virus entry or the primary infection cycle are not the principal determinants of host specificity of Spodoptera spp. nucleopolyhedroviruses

Journal of General Virology, 2004
The multicapsid nucleopolyhedroviruses (NPVs) of Spodoptera exigua (SeMNPV), Spodoptera frugiperda (SfMNPV), and Spodoptera littoralis (SpliNPV) are genetically similar (78 % similarity) but differ in their degree of host specificity. Infection by each of the three NPVs in these three Spodoptera host species was determined by oral inoculation of larvae

Comparative analysis of the complete genome sequences of Helicoverpa zea and Helicoverpa armigera single-nucleocapsid nucleopolyhedroviruses

Journal of General Virology, 2002
The complete nucleotide sequence of Helicoverpa zea single-nucleocapsid nucleopolyhedrovirus (HzSNPV) has been determined (130869 bp) and compared to the nucleotide sequence of Helicoverpa armigera (Ha) SNPV. These two genomes are very similar in their nucleotide (97% identity) and amino acid (99% identity) sequences.
