Quantification of dose-mortality responses in adult Diptera: validation using Ceratitis capitata and Drosophila suzukii responses to spinosad
(Public Library of Science, 2019)
info:eu-repo/semantics/article,
Quantitative laboratory bioassay methods are required to evaluate the toxicity of novel insecticidal compounds for pest control and to determine the presence of resistance traits. We used a radioactive tracer based on ...
Nucleopolyhedrovirus coocclusion technology: a new concept in the development of biological insecticides
(Frontiers Media, 2022)
Artículo / Artikulua,
Nucleopolyhedroviruses (NPV, Baculoviridae) that infect lepidopteran pests have an established record as safe and effective biological insecticides. Here, we describe a new approach for the development of NPV-based ...
Genetic variability of Chrysodeixis includens nucleopolyhedrovirus (ChinNPV) and the insecticidal characteristics of selected genotypic variants
(MDPI, 2019)
info:eu-repo/semantics/article,
Genetic variation in baculoviruses is recognized as a key factor, not only due to the influence of such variation on pathogen transmission and virulence traits, but also because genetic variants can form the basis for novel ...
A strain of Bacillus thuringiensis containing a novel cry7Aa2 gene that is toxic to Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae)
(MDPI, 2019)
info:eu-repo/semantics/article,
The genome of the Bacillus thuringiensis BM311.1 strain was sequenced and assembled in 359 contigs containing a total of 6,390,221 bp. The plasmidic ORF of a putative cry gene from this strain was identified as a potential ...
Bacmid expression of granulovirus enhancin En3 accumulates in cell soluble fraction to potentiate nucleopolyhedrovirus infection
(MDPI, 2021)
info:eu-repo/semantics/article,
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 ...
Coocclusion of Helicoverpa armigera single nucleopolyhedrovirus (HearSNPV) and Helicoverpa armigera multiple nucleopolyhedrovirus (HearMNPV): pathogenicity and stability in homologous and heterologous hosts
(MDPI, 2022)
info:eu-repo/semantics/article,
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 ...
Insecticidal activity of bacillus thuringiensis proteins against coleopteran pests
(MDPI, 2020)
info:eu-repo/semantics/article,
Bacillus thuringiensis is the most successful microbial insecticide agent and its proteins have been studied for many years due to its toxicity against insects mainly belonging to the orders Lepidoptera, Diptera and ...
Potential of Cry10Aa and Cyt2Ba, two minority δ-endotoxins produced by Bacillus thuringiensis ser. israelensis, for the control of Aedes aegypti larvae
(MDPI, 2020)
info:eu-repo/semantics/article,
Bacillus thuringiensis ser. israelensis (Bti) has been widely used as microbial larvicide for the control of many species of mosquitoes and blackflies. The larvicidal activity of Bti resides in Cry and Cyt δ-endotoxins ...
Baculovirus expression and functional analysis of Vpa2 proteins from Bacillus thuringiensis
(MDPI, 2020)
info:eu-repo/semantics/article,
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 ...
Genetic variation and biological activity of two closely related alphabaculoviruses during serial passage in permissive and semi-permissive heterologous hosts
(MDPI, 2019)
info:eu-repo/semantics/article,
Phylogenetic analyses suggest that Mamestra brassicae multiple nucleopolyhedrovirus (MbMNPV) and Helicoverpa armigera multiple nucleopolyhedrovirus (HearMNPV) may be strains of the same virus species. Most of the studies ...
