Genetic basis of codling moth (Cydia pomonella) resistance to the original isolate of C. pomonella Granulovirus (CpGV-M)

Entomologia Generalis, 2023
The utilization of insect pest pathogens as biocontrol agents can serve as an effective alternative to chemical pesticides. However, pests can develop resistance to these pathogens, similar to resistance observed with chemicals. Identifying the genetic bases of resistance is a crucial step in comprehending the co-evolution mechanisms between insect ...

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 ...

A comparison of the EU and US regulatory frameworks for the active substance registration of microbial biological control agents

Pest Management Science, Volume 75, Issue 1, Page 87-103, January 2019., 2019
This article compares the regulation of microbial biopesticide registration in the European Union (EU) and the USA, discussing regulatory differences and resulting obstacles. EU registration takes substantially longer, lagging mostly at the national level.

Granulovirus GP37 Facilitated ODVs Cross Insect Peritrophic Membranes and Fuse with Epithelia

Toxins, 2019
The Cydia pomonella granulovirus (CpGV) GP37 has synergistic effects on the infectivity of nucleopolyhedroviruses (NPVs), however, the mechanism employed is unclear. In this study, in vitro and in vivo binding assays indicated that GP37 efficiently bound

Regulation of Cydia pomonella in the Northern German climate [PDF]

, 2008
Population control of the codling moth (Cydia pomonella) is of great importance in ecological fruit-growing. In the work described here we attempted (1) to determine the efficacy of plant protection preparations certified for organic fruit production ...

Monitoring resistance of Cydia pomonella (L.) Spanish field populations to new chemical insecticides and the mechanisms involved [PDF]

, 2017
BACKGROUND: A widespread resistance of Cydia pomonella to organophosphates was demonstrated in populations from the Spanish Ebro Valley area that showed high levels of enzymatic detoxification.

Increased proportion of exclusion netting in the landscape affects pest damage in unnetted apple orchards

Journal of Applied Ecology, Volume 62, Issue 4, Page 790-800, April 2025.
This study is the first to reveal that nets significantly impact pest dynamics on the scale of agricultural landscapes. We recommend landscape‐scale coordination in the deployment of nets, along with additional protective measures to mitigate their unintended effects on pests at the local and landscape scales.

Update of the list of QPS‐recommended biological agents intentionally added to food or feed as notified to EFSA 7: suitability of taxonomic units notified to EFSA until September 2017

EFSA Journal, Volume 16, Issue 1, January 2018., 2018
Abstract The qualified presumption of safety (QPS) concept was developed to provide a harmonised generic pre‐evaluation to support safety risk assessments of biological agents performed by EFSA's scientific Panels. The identity, body of knowledge, safety concerns and antimicrobial resistance of valid taxonomic units were assessed.

Importance of the Host Phenotype on the Preservation of the Genetic Diversity in Codling Moth Granulovirus

Viruses, 2019
To test the importance of the host genotype in maintaining virus genetic diversity, five experimental populations were constructed by mixing two Cydia pomonella granulovirus isolates, the Mexican isolate CpGV-M and the CpGV-R5, in ratios of 99% M + 1% R,
