Biological and Biochemical Relationships between the Nucleopolyhedroviruses of Mamestra brassicae and Heliothis armigera

Journal of Invertebrate Pathology, 2000
The multiply embedded nucleopolyhedroviruses (MNPV) originally isolated from Mamestra brassicae (German and Dutch isolates) and Heliothis armigera have been studied comparatively to establish their relatedness, both in terms of biological activity and genomic homology. All three viral isolates replicated in M. brassicae, H. armigera, Heliothis zea, and

P143 proteins from heterologous nucleopolyhedroviruses induce apoptosis in BM-N cells derived from the silkworm Bombyx mori

Virus Research, 2017
We previously demonstrated that ribosomal RNA (rRNA) of Bombyx mori BM-N cells is rapidly degraded upon infection with heterologous nucleopolyhedroviruses (NPVs), including Autographa californica multiple NPV (AcMNPV), Hyphantria cunea MNPV, Spodoptera exigua MNPV and S. litura MNPV, and that this response is triggered by viral P143 proteins.

Comparative analysis of budded virus infectivity of Bombyx mandarina and B. mori nucleopolyhedroviruses

Virus Genes, 2011
Bombyx mandarina nucleopolyhedrovirus (BomaNPV) is a variant of Bombyx mori nucleopolyhedrovirus (BmNPV). BomaNPV S1 strain has been reported to be significantly less virulent than the BmNPV T3 strain via the oral infection route in B. mori larvae, but other features of S1 including budded virus (BV) infectivity and virus propagation in cultured cells ...

Ecology of insect nucleopolyhedroviruses

Agriculture, Ecosystems & Environment, 2004
Abstract The underlying thesis of this paper is that nucleopolyhedroviruses (NPV), like their insect hosts, exist as populations that can be considered in an ecological context. Population dynamics and transport within and from soil are basic to ecology and, in many cases, long-term survival of NPVs.

Bollworm responses to release of genetically modified Helicoverpa armigera nucleopolyhedroviruses in cotton

Journal of Invertebrate Pathology, 2002
Helicoverpa armigera single nucleocapsid nucleopolyhedrovirus (HaSNPV) has been developed as a commercial biopesticide to control the cotton bollworm, H. armigera, in China. The major limitation to a broader application of this virus has been the relative long time to incapacitate the target insect.

Comparative analysis of the genomes of Bombyx mandarina and Bombyx mori nucleopolyhedroviruses

The Journal of Microbiology, 2010
The Bombyx mandarina nucleopolyhedrovirus (BomaNPV) S1 strain can infect the silkworm, Bombyx mori, but is significantly less virulent than B. mori nucleopolyhedrovirus (BmNPV) T3 strain. The complete nucleotide sequence of the S1 strain of BomaNPV was determined and compared with the BmNPV T3 strain.

Host range of two multiple nucleopolyhedroviruses isolated from Spodoptera litura

Biological Control, 2007
Abstract Twenty-two lepidopteran and one termite nontarget species were challenged with the in vivo -cloned Spodoptera littoralis multicapsid nucleopolyhedrovirus (SpliMNPV) or Spodoptera litura multicapsid NPV (SpltMNPV). S. litura larvae were used as controls to verify the infectivity of the NPV.

Comparative Infectivity of Homologous and Heterologous Nucleopolyhedroviruses against Beet Armyworm Larvae

Journal of Agricultural and Urban Entomology, 2016
ABSTRACT  Homologous and heterologous nucleopolyhedroviruses (NPVs) were assayed to determine their effectiveness against beet armyworm larvae, Spodoptera exigua (Hubner) (Lepidoptera: Noctuidae). Included were three NPV isolates from S. exigua, one isolate each from S. littoralis Boisduval, S. litura (F.), and S.

Development of a dipstick immunoassay to detect nucleopolyhedroviruses in Douglas-fir tussock moth larvae

Journal of Virological Methods, 2007
In this paper, we describe the development of a novel field detection system for the identification of Orgyia pseudotsugata nucleopolyhedrovirus (OpNPV) and OpNPV infections in Douglas-fir tussock moth (O. pseudotsugata) (DFTM) larvae, utilizing antibodies in a dipstick immunoassay.

Hierarchical spatial structure of genetically variable nucleopolyhedroviruses infecting cyclic populations of western tent caterpillars

Molecular Ecology, 2003
AbstractThe cyclic population dynamics of western tent caterpillars, Malacosoma californicum pluviale, are associated with epizootics of a nucleopolyhedrovirus, McplNPV. Given the dynamic fluctuations in host abundance and levels of viral infection, host resistance and virus virulence might be expected to change during different phases of the cycle. As
