Resource quality determines the evolution of resistance and its genetic basis

Molecular Ecology, Volume 29, Issue 21, Page 4128-4142, November 2020., 2020
Abstract Parasites impose strong selection on their hosts, but the level of any evolved resistance may be constrained by the availability of resources. However, studies identifying the genomic basis of such resource‐mediated selection are rare, particularly in nonmodel organisms.

Virulence and competitiveness of Cydia pomonella granulovirus mutants: parameters that do not match

Journal of General Virology, 2005
The LD50, median survival time (ST50) and virus production are virulence parameters that are commonly used to describe the biological characteristics of viruses. In this study, these parameters were determined for Cydia pomonella granulovirus (CpGV-M) and two naturally occurring mutants (CpGV-MCp4 and -MCp5) that carry Tc1-like insect transposable ...

Monitoring and possibilities of controlling nematodes and fruit damaging pests of Rosa spp. with microbial-derived products

Journal of Plant Protection Research, 2019
Interest in growing roses in Poland is related to the production of cut flowers as ornamentals and of petals and hips for cosmetics or food products. However, recently there has been an increasing number of reports of pest damage on rose plantations ...

Comparison of the potential activities of viral and bacterial chitinases

Egyptian Journal of Biological Pest Control, 2021
Background Chitin, a long-chain polymer of N-acetylglucosamine, is a major structural component of the insect exoskeleton and the peritrophic membrane (PM). Chitinases are able to effectively break down glycosidic bonds of chitin polymer thus can be used

Single nucleotide polymorphism (SNP) frequencies and distribution reveal complex genetic composition of seven novel natural isolates of Cydia pomonella granulovirus.

Virology, 2019
The co-evolution between baculoviruses and their insect hosts results in selection of virus populations. To explore this phenomenon at the molecular level, seven natural isolates of Cydia pomonella granulovirus (CpGV) collected from orchards in northwest

Is the efficacy of biological control against plant diseases likely to be more durable than that of chemical pesticides?

Frontiers in Plant Science, 2015
The durability of a control method for plant protection is defined as the persistence of its efficacy in space and time. It depends on (i) the selection pressure exerted by it on populations of plant pathogens and (ii) on the capacity of these pathogens ...

Progressive Adaptation of a CpGV Isolate to Codling Moth Populations Resistant to CpGV-M

Viruses, 2014
The NPP-R1 isolate of CpGV is able to replicate on CpGV-M-resistant codling moths. However, its efficacy is not sufficient to provide acceptable levels of control in natural (orchard) conditions.

Controlled beams of shock-frozen, isolated, biological and artificial nanoparticles

Structural Dynamics, 2020
X-ray free-electron lasers promise diffractive imaging of single molecules and nanoparticles with atomic spatial resolution. This relies on the averaging of millions of diffraction patterns of identical particles, which should ideally be isolated in the ...

First Report for Pathogenity of Cydia Pomonella Granulovirus and Helicoverpa Armigera Nucleopolyhedrovirus to Indian Meal Moth Plodia Interpunctella Hϋbner (Lepidoptera: Pyralidae) in Vitro

Journal of Agriculture and Sustainability, 2020
The purpose of this study was to examine the for the first time the effect of Cydia pomonella granulovirus and Helicoverpa armigera nucleopolyhedrovirus on the larvae of the Lepidopteran Plodia interpunctella .

Bacsnp: Using Single Nucleotide Polymorphism (SNP) Specificities and Frequencies to Identify Genotype Composition in Baculoviruses

Viruses, 2020
Natural isolates of baculoviruses (as well as other dsDNA viruses) generally consist of homogenous or heterogenous populations of genotypes. The number and positions of single nucleotide polymorphisms (SNPs) from sequencing data are often used as ...
