Determination of virulence and genetic variability of three Spodoptera littoralis nucleopolyhedrovirus isolates from Egypt

Egyptian Journal of Biological Pest Control, 2022
Background The genetic diversity is naturally occurring in baculovirus population, which may affect the potency of the bio-agent. The Spodoptera littoralis nucleopolyhedrovirus is a promising bio-control agent that can be used to control the cotton ...

DNA photolyases of Chrysodeixis chalcites nucleopolyhedrovirus are targeted to the nucleus and interact with chromosomes and mitotic spindle structures

, 2010
Cyclobutane pyrimidine dimer (CPD) photolyases convert UV-induced CPDs in DNA into monomers using visible light as the energy source. Two phr genes encoding class II CPD photolyases PHR1 and PHR2 have been identified in Chrysodeixis chalcites ...

Two Year Field Study to Evaluate the Efficacy of Mamestra brassicae Nucleopolyhedrovirus Combined with Proteins Derived from Xestia c-nigrum Granulovirus

Viruses, 2015
Japan has only three registered baculovirus biopesticides despite its long history of studies on insect viruses. High production cost is one of the main hindrances for practical use of baculoviruses. Enhancement of insecticidal effect is one possible way

Carbohydrate metabolism is a determinant for the host specificity of baculovirus infections

iScience, 2022
Summary: Baculoviruses Autographa californica multicapsid nucleopolyhedrovirus (AcMNPV) and Bombyx mori nucleopolyhedrovirus (BmNPV) have highly similar genome sequences but exhibit no overlap in their host range.

Effects of single and mixed infections with wild type and genetically modified Helicoverpa armigera nucleopolyhedrovirus on movement behaviour of cotton bollworm larvae

, 2010
Naturally occurring insect viruses can modify the behaviour of infected insects and thereby modulate virus transmission. Modifications of the virus genome could alter these behavioural effects.

Baculovirus Genetic Diversity and Population Structure

Viruses
Baculoviruses can naturally regulate lepidopteran populations and are used as biological insecticides. The genetic diversity of these viruses affects their survival and efficacy in pest control.

Preparation and performance of insect virus microcapsules

Egyptian Journal of Biological Pest Control, 2021
Background Biological pesticides, especially baculovirus, often lose their activity under the influence of external light, temperature, and other changes. This limited the application of them.

Gender-Mediated Differences in Vertical Transmission of a Nucleopolyhedrovirus

PLoS ONE, 2013
With the development of sensitive molecular techniques for detection of low levels of asymptomatic pathogens, it becoming clear that vertical transmission is a common feature of some insect pathogenic viruses, and likely to be essential to virus survival when opportunities for horizontal transmission are unfavorable. Vertical transmission of Spodoptera

Field Efficacy and Transmission of Fast- and Slow-Killing Nucleopolyhedroviruses that Are Infectious to Adoxophyes honmai (Lepidoptera: Tortricidae)

Viruses, 2015
The smaller tea tortrix, Adoxophyes honmai (Lepidoptera: Tortricidae), is an economically important pest of tea in Japan. Previous work showed that a fast-killing nucleopolyhedrovirus (NPV) isolated from A. orana (AdorNPV) and a slow-killing NPV isolated
