Analagous population structures for two alphabaculoviruses highlight a functional role for deletion mutants
A natural Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) isolate from Florida shares a strikingly similar genotypic composition to that of a natural Spodoptera frugiperda MNPV (SfMNPV) isolate from Nicaragua. ... -
Anticarsia gemmatalis nucleopolyhedrovirus from soybean crops in Tamaulipas, Mexico: diversity and insecticidal characteristics of individual variants and their co-occluded mixtures
In 1999, Anticarsia gemmatalis nucleopolyhedrovirus (AgMNPV) was introduced into a major soybean-growing region in Tamaulipas, Mexico, for control of its lepidopteran host, Anticarsia gemmatalis Hilbner (Lepidoptera: ... -
Bacillus thuringiensis Cyt proteins as enablers of activity of Cry and Tpp toxins against Aedes albopictus
Aedes albopictus is a species of mosquito, originally from Southeast Asia, that belongs to the Culicidae family and the Dipteran insect order. The distribution of this vector has rapidly changed over the past decade, making ... -
Bacillus thuringiensis toxins: an overview of their biocidal activity
Bacillus thuringiensis (Bt) is a Gram positive, spore-forming bacterium that synthesizes parasporal crystalline inclusions containing Cry and Cyt proteins, some of which are toxic against a wide range of insect orders, ... -
Bacmid expression of granulovirus enhancin En3 accumulates in cell soluble fraction to potentiate nucleopolyhedrovirus infection
Enhancins are metalloproteinases that facilitate baculovirus infection in the insect midgut. They are more prevalent in granuloviruses (GVs), constituting up to 5% of the proteins of viral occlusion bodies (OBs). In ... -
Baculovirus expression and functional analysis of Vpa2 proteins from Bacillus thuringiensis
The mode of action underlying the insecticidal activity of the Bacillus thuringiensis (Bt) binary pesticidal protein Vpa1/Vpa2 is uncertain. In this study, three recombinant baculoviruses were constructed using Bac-to-Bac ... -
Biotechnological development of a new bioinsecticide based on a Helicoverpa armigera nucleopolyhedrovirus from Spain
El taladro del tomate, Helicoverpa armigera (Hübner) (Lepidoptera: Noctuidae), es una de las principales plagas polífagas de la Península Ibérica. El nucleopoliedrovirus simple de H. armigera (HearSNPV) es un método eficaz ... -
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
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 ... -
Chrysodeixis chalcites nucleopolyhedrovirus: a useful component for IPM programs on the Canary Islands banana crops
La platanera (Musa acuminata Colla) es uno de los principales cultivos de las Islas Canarias, representando el 30% de la producción agrícola total del archipiealago. Dicho cultivo se realiza bajo invernaderos de malla ... -
A Chrysodeixis chalcites single-nucleocapsid nucleopolyhedrovirus population from the Canary Islands is genotypically structured to maximize survival
A Chrysodeixis chalcites single-nucleocapsid nucleopolyhedrovirus wild-type isolate from the Canary Islands, Spain, named ChchSNPV-TF1 (ChchTF1-wt), appears to have great potential as the basis for a biological insecticide ... -
Co-infection with iflaviruses influences the insecticidal properties of Spodoptera exigua multiple nucleopolyhedrovirus occlusion bodies: implications for the production and biosecurity of baculovirus insecticides
Biological insecticides based on Spodoptera exigua multiple nucleopolyhedrovirus (SeMNPV) can efficiently control S. exigua larvae on field and greenhouse crops in many parts of the world. Spanish wild populations and ... -
Coocclusion of Helicoverpa armigera single nucleopolyhedrovirus (HearSNPV) and Helicoverpa armigera multiple nucleopolyhedrovirus (HearMNPV): pathogenicity and stability in homologous and heterologous hosts
Helicoverpa armigera single nucleopolyhedrovirus (HearSNPV) is a virulent pathogen of lepidopterans in the genera Heliothis and Helicoverpa, whereas Helicoverpa armigera multiple nu-cleopolyhedrovirus (HearSNPV) is a ... -
Coping with environmental eukaryotes; identification of Pseudomonas syringae genes during the interaction with alternative hosts or predators
Understanding the molecular mechanisms underpinning the ecological success of plant pathogens is critical to develop strategies for controlling diseases and protecting crops. Recent observations have shown that plant ... -
Deletion genotypes reduce occlusion body potency but increase occlusion body production in a Colombian Spodoptera frugiperda nucleopolyhedrovirus population
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
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 ... -
