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.

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

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 ...

Pathology of Anticarsia gemmatalis larvae infected by two recombinant A. gemmatalis multicapsid nucleopolyhedroviruses

Research in Microbiology, 2005
Light and stereomicroscopy examinations of Anticarsia gemmatalis multicapsid nucleopolyhedrovirus (AgMNPV)-infected insects were performed in order to follow infection in its host, A. gemmatalis. Fourth-instar A. gemmatalis larvae were infected by administration of occluded virus (polyhedra) from two recombinant AgMNPV viruses (vAgEGTDelta-lacZ or ...

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.

Synergistic effects of Cydia pomonella granulovirus GP37 on the infectivity of nucleopolyhedroviruses and the lethality of Bacillus thuringiensis

Archives of Virology, 2011
To initiate an efficient primary infection, it is important for baculovirus virions to penetrate through the peritrophic membrane (PM) of the host insect. It is frequently reported that enhancins of baculoviruses significantly enhance viral infection by degrading the various protein components of PMs.

A rapid method for the identification and differentiation of Helicoverpa nucleopolyhedroviruses (NPV Baculoviridae) isolated from the environment

Journal of Virological Methods, 2001
A diagnostic method is described for the identification and differentiation of nucleopolyhedrovirus (NPV) pathogens of Helicoverpa species (Lepidoptera: Noctuidae) isolated from the environment. The method is based on the polymerase chain reaction (PCR) used in conjunction with restriction fragment length polymorphism (RFLP) analysis and comprises ...

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

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

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.
