Ecology of insect nucleopolyhedroviruses

Agriculture, Ecosystems and 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.

Eicosanoids influence insect susceptibility to nucleopolyhedroviruses

Journal of Invertebrate Pathology, 2009
Nine pharmaceutical inhibitors of eicosanoid biosynthesis (e.g., bromophenacyl bromide, clotrimazole, diclofenamic acid, esculetin, flufenamic acid, indomethacin, nimesulide, sulindac, tolfenamic acid) that increased the susceptibility of the gypsy moth, Lymantria dispar (L.), to the nucleopolyhedrovirus LdMNPV were tested against the beet armyworm ...

Interactions Between Nucleopolyhedroviruses and Polydnaviruses in Larval Lepidoptera

, 2012
The field dynamics of some insect populations are strongly influenced by two types of insect viruses: the nucleopolyhedroviruses (NPVs) and the polydnaviruses (PDVs). Although greatly different in origin and mode of infection, both viruses produce considerable mortality directly and indirectly in the field, and have evolved reproductive strategies that

Persistence and Distribution of Wild-Type and Recombinant Nucleopolyhedroviruses in Soil

Microbial Ecology, 2001
Persistence of recombinant and wild-type nucleopolyhedroviruses (NPV) was compared in field and laboratory microcosm experiments. Horizontal and vertical distribution of the viruses also was monitored in the field agricultural soil. Mixed populations of the bollworm, Helicoverpa zea, and tobacco budworm, Heliothis virescens, in cotton were sprayed five

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.

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.

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 ...
