Molecular biology of baculovirus and its use in biological control in Brazil Biologia molecular de baculovírus e seu uso no controle biológico de pragas no Brasil

Pesquisa Agropecuária Brasileira, 1999
Baculoviruses are insect viruses found mainly in Lepidoptera. The family Baculoviridae is taxonomically divided in two genera, Nucleopolyhedrovirus and Granulovirus, which differ by occlusion body morphology.

Role of nucleopolyhedroviruses (NPVs) in the management of lepidopteran pests in Asia

, 2017
Lepidopteran insect pest species cause heavy damage to the crop yield annually around the globe. Baculoviruses, the nucleopolyhedroviruses and the granuloviruses, act as natural regulators of pest populations including lepidopteran pests, and their ...

Harnessing Chelonus inanitus for efficient Spodoptera spp. management: Learning about production to explore roles in Baculovirus transmission

Biological Control
Control of Spodoptera spp. (Lepidoptera: Noctuidae) crop pests has traditionally relied on heavy insecticide use. Baculoviruses (BV) from the genera Alphabaculovirus and Betabaculovirus offer effective, species-specific alternatives for managing their ...

In vitro phagocytosis of occlusion bodies of nucleopolyhedroviruses by insect cell lines.

Applied Entomology and Zoology, 2001
The phagocytosis of five established cell lines, IPLB-Sf-5-5C, UCR-Se-1, NTU-Sl-1A, NTU-Pn-HH, and IPLB-Ld652Y was examined by fluoresbrite carbosylate particle uptake. The phagocytic action of the Sf-5-5C cells was highly efficient compared to other cells, while Pn-HH cells showed no phagocytic action.

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.

On the classification and nomenclature of baculoviruses: A proposal for revision [PDF]

, 2006
Recent evidence from genome sequence analyses demands a substantial revision of the taxonomy and classification of the family Baculoviridae. Comparisons of 29 baculovirus genomes indicated that baculovirus phylogeny followed the classification of the ...

Baculovirus nucleocapsid aggregation (MNPV vs SNPV): an evolutionary strategy, or a product of replication conditions?

Lepidopteran nucleopolyhedroviruses are members of the Baculoviridae and have been categorized as having two morphotypes of occluded virions: multiple nucleocapsids or single nucleocapsids within the virion envelope.

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.

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.

Identification of a Novel Apoptosis Suppressor Gene from the Baculovirus Lymantria dispar Multicapsid Nucleopolyhedrovirus

, 2011
Ld652Y cells from Lymantria dispar readily undergo apoptosis upon infection with a variety of nucleopolyhedroviruses (NPVs), while L. dispar multicapsid NPV (LdMNPV) infection of Ld652Y cells results in the
