Differences in nutritional requirements of adult codling moth, Cydia pomonella (L.), from field and laboratory populations

Journal of Applied Entomology, Volume 148, Issue 9, Page 1094-1104, November 2024.
Abstract The codling moth Cydia pomonella (Linnaeus) (Lepidoptera: Tortricidae) is one of the most important pests in apple production. The provision of sugar resources improved adult fitness of this species in laboratory studies and could also be enhanced in the field, for example, by naturally occurring carbohydrate sources in the orchard environment.

Update of the list of QPS‐recommended biological agents intentionally added to food or feed as notified to EFSA 4: suitability of taxonomic units notified to EFSA until March 2016

EFSA Journal, Volume 14, Issue 7, July 2016., 2016
Abstract EFSA was requested to assess the safety of a broad range of biological agents in the context of notifications for market authorisation as sources of food and feed additives, enzymes and plant protection products. The qualified presumption of safety (QPS) assessment was developed to provide a harmonised generic preassessment to support safety ...

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,

Evaluation of Commercial Virus Biopesticides for the Control of Moth Pests in Laboratory Conditions: The Cases of Thaumetopoea pityocampa and Helicoverpa armigera

Applied Sciences
The research on entomopathogenic viruses is of major significance as they could serve as alternatives to chemical pesticides. There are various types of entomopathogenic viruses; among them, Baculoviruses (BVs) are a potential option because they are eco-

Type V: A sex-linked crossed resistance to three Cydia pomonella granulovirus isolates, with different levels of dominance

Biological Control
The codling moth (Cydia pomonella), is known to be resistant to many (bio)insecticides, including the Cydia pomonella granulovirus (CpGV). Of the multiple isolates available on the European market, two are already known to have selected resistance: Type ...

Host range extension of Cydia pomonella granulovirus: adaptation to Oriental Fruit Moth, Grapholita molesta

, 2017
Among various Cydia pomonella granulovirus (CpGV) isolates, the Mexican isolate (CpGV-M) has demonstrated a significant ability to reduce damage induced by the oriental fruit moth, Grapholita molesta (Busck) (=Cydia molesta) in peach crops.

A single sex-linked dominant gene does not fully explain the codling moth's resistance to granulovirus

, 2013
Background: In 2004, resistance to a commercial formulation of the Cydia pomonella granulovirus (CpGV) was identified in a field population of Cydia pomonella from an organic orchard in southern France.

Polymerase chain reaction assay for Cydia pomonella granulovirus detection in Cydia pomonella population.

Acta virologica, 2004
The polymerase chain reaction (PCR) assay was successfully used to identify Cydia pomonella granulovirus (CpGV) in larvae of Cydia pomonella L. (codling moth). PCR with the primers CpGV-2A/CpGV-2B and CpGV-3A/CpGV-3B was found suitable for detection of CpGV.
