Mixtures of complete and pif1- and pif2-deficient genotypes are required for increased potency of an insect nucleopolyhedrovirus
(American Society for Microbiology, 2009)
info:eu-repo/semantics/article,
The insecticidal potency of a nucleopolyhedrovirus population (SfNIC) that infects Spodoptera frugiperda
(Lepidoptera) is greater than the potency of any of the component genotypes alone. Occlusion bodies (OBs)
produced ...
Functional importance of deletion mutant genotypes in an insect nucleopolyhedrovirus population
(American Society for Microbiology, 2005)
info:eu-repo/semantics/article,
A Nicaraguan isolate of a nucleopolyhedrovirus (SfNIC) that attacks the fall armyworm, Spodoptera frugiperda, survives as a mixture of nine genotypes (SfNIC A to I) that all present genomic deletions, except variant B ...
Genomic sequences of five Helicoverpa armigera nucleopolyhedrovirus genotypes from Spain that differ in their insecticidal properties
(American Society for Microbiology, 2015)
info:eu-repo/semantics/article,
Helicoverpa armigera nucleopolyhedrovirus (HearNPV) has proved effective as the basis for various biological insecticides. Complete genome sequences of five Spanish HearNPV genotypes differed principally in the homologous ...
Genetic structure of a Spodoptera frugiperda nucleopolyhedrovirus population: high prevalence of deletion genotypes
(American Society for Microbiology, 2004)
info:eu-repo/semantics/article,
A Nicaraguan field isolate (SfNIC) of Spodoptera frugiperda nucleopolyhedrovirus was purified by plaque assay on Sf9 cells. Nine distinct genotypes, A to I, were identified by their restriction endonuclease profiles. Variant ...
Chrysodeixis chalcites nucleopolyhedrovirus (ChchNPV): natural occurrence and efficacy as a biological insecticide on young banana plants in greenhouse and open-field conditions on the Canary Islands
(Public Library of Science, 2017)
info:eu-repo/semantics/article,
Chrysodeixis chalcites, an important pest of banana crops on the Canary Islands, is usually
controlled by chemical insecticides. The present study aimed to evaluate the efficacy of the
most prevalent isolate of the ...
Lacanobia oleracea nucleopolyhedrovirus (LaolNPV): a new European species of alphabaculovirus with a narrow host range
(Public Library of Science, 2017)
info:eu-repo/semantics/article,
During an insect sampling program in alfalfa crops near Montpellier, France in 2011, Lacanobia oleracea larvae were collected that died due to nucleopolyhedrovirus infection (LaolNPV). This virus was subjected to molecular ...
Expression of a peroral infection factor determines pathogenicity and population structure in an insect virus
(Public Library of Science, 2013)
info:eu-repo/semantics/article,
A Nicaraguan isolate of Spodoptera frugiperda multiple nucleopolyhedrovirus is being studied as a possible biological
insecticide. This virus exists as a mixture of complete and deletion genotypes; the latter depend on ...
The sf32 unique gene of spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) is a non-essential gene that could be involved in nucleocapsid organization in occlusion-derived virions
(Public Library of Science, 2013)
info:eu-repo/semantics/article,
A recombinant virus lacking the sf32 gene (Sf32null), unique to the Spodoptera frugiperda multiple nucleopolyhedrovirus
(SfMNPV), was generated by homologous recombination from a bacmid comprising the complete viral genome ...
Deletion genotypes reduce occlusion body potency but increase occlusion body production in a Colombian Spodoptera frugiperda nucleopolyhedrovirus population
(Public Library of Science, 2013)
info:eu-repo/semantics/article,
A Colombian field isolate (SfCOL-wt) of Spodoptera frugiperda multiple nucleopolyhedrovirus (SfMNPV) is a mixture
of different genotypes. To evaluate the insecticidal properties of the different genotypic variants, 83 ...
Determinant factors in the production of a co-occluded binary mixture of Helicoverpa armigera alphabaculovirus (HearNPV) genotypes with desirable insecticidal characteristics
(Public Library of Science, 2016)
info:eu-repo/semantics/article,
A co-occluded binary mixture of Helicoverpa armigera nucleopolyhedrovirus genotypes HearSP1B and HearLB6 at a 1:1 ratio (HearSP1B+HearLB6) was selected for the development of a virus-based biological insecticide, which ...
