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

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

Nucleopolyhedroviruses (NPV) induce the expression of small heat shock protein 25.4 in Antheraea pernyi

Gene, 2016
Nucleopolyhedroviruses (NPVs) is one group of Baculoviruses. The infection of NPV in silkworm is often lethal. To investigate the effective measures to stop the infection of NPV, we cloned cDNA encoding small heat shock protein 25.4 in Antheraea pernyi (Ap-HSP25.4).

Competition between Wild-Type and Recombinant Nucleopolyhedroviruses in a Greenhouse Microcosm

Biological Control, 2001
Abstract Wild-type Autographa californica nucleopolyhedrovirus (AcNPV or AcNPV.WT), AcNPV expressing a scorpion toxin (AcNPV.AaIT), and AcNPV expressing a mutated juvenile hormone esterase (AcJHE.SG) were compared in their capability to produce epizootics in larvae of Trichoplusia ni infesting collards in a greenhouse microcosm. Larvae treated in

Persistence of naturally occurring and genetically modified Choristoneura fumiferana nucleopolyhedroviruses in outdoor aquatic microcosms

Pest Management Science, 2008
Abstract BACKGROUND: To assess the persistence of genetically modified and naturally occurring baculoviruses in an aquatic environment, replicate (three) outdoor, aquatic microcosms were spiked with spruce budworm viruses [Ireland strain of Choristoneura fumiferana

Host-range testing of a mixture of two nucleopolyhedroviruses of Choristoneura fumiferana (Lepidoptera: Tortricidae)

The Canadian Entomologist, 2011
AbstractThe host range of a mixture of Choristoneura fumiferana (Clemens) nucleopolyhedroviruses (CfMNPV and CfDefNPV) was investigated using a per os bioassay of larvae of 29 species of Lepidoptera and adult males of Megachile rotundata (F.) (Hymenoptera: Megachilidae).

Effects of Cucurbitacin on the Activity of Nucleopolyhedroviruses Against Pickleworm Larvae²

Journal of Agricultural and Urban Entomology, 2009
Abstract The cucurbitacin-containing feeding stimulant (Invite® EC) was attractive to second instar pickleworm larvae in the absence of a food source. Second instar pickleworm larvae also fed preferentially on cucumber fruits that were treated with a 1% (0.01×) solution of Invite EC compared with untreated fruit.

The putative LEF-1 proteins from two distinct Choristoneura fumiferana multiple nucleopolyhedroviruses share domain homology to eukaryotic primases

Virus Genes, 1996
We have identified the lef-1 genes from two multiple nucleopolyhedroviruses that infect natural populations of Choristoneura fumiferana. The lef-1 genes in both viruses are directly upstream and in the opposite orientation of their respective ecdysteroid UDP-glucosyltransferase (egt) genes. This gene organization pattern is similar to that found in the
