Cydia pomonella granulovirus (CpGV) has received considerable attention as a potential microbial insecticide for the control of the codling moth (Cydia pomonella L.) , a worldwide pest of apples. Laboratory experiments were established to investigate virus uptake by first instar larvae, using a novel leaf disc bioassay technique. Virus uptake was found to be independent of active feeding and larvae became infected simply by walking or browsing on sprayed leaf disc surfaces in as little time as… Expand
Persistence of a commercial codling moth granulovirus product on apple fruit and foliage
TLDR
The addition of fish, soybean or mineral oils to Virosoft CP4® treatments did not significantly increase the efficacy or persistence of the viral insecticide on apples in this study. Expand
Genetic and biological characterisation of a novel South African Cydia pomonella granulovirus (CpGV-SA) isolate
TLDR
To isolate a baculovirus from a laboratory-reared P. xylostella colony, characterise it genetically and then evaluate its virulence against neonate and fourth instar larvae, this study aimed to isolate a novel South African PlxyGV isolate. Expand
Comparative Activity of the Codling Moth Granulovirus Against Grapholita molesta and Cydia pomonella (Lepidoptera: Tortricidae)
TLDR
Comparative assays of CpGV against Neonate larvae of another introduced tortricid pest, the oriental fruit moth, revealed a 557 and 589 fold lower susceptibility of neonate larvae compared with the LC50 and LC95 values derived for C. pomonella. Expand
The biological efficacy of pear ester on the activity of Granulosis virus for codling moth
TLDR
A significant effect of the blank DA-MEC formulation in reducing fruit injury compared to an unsprayed control is revealed and this results in the potential of improving the insecticidal performance of the granulovirus of C. pomonella (CpGV) by co-mixing with pear ester in a sprayable formulation. Expand
Field evaluation of commercial formulations of the codling moth granulovirus: persistence of activity and success of seasonal applications against natural infestations of codling moth in Pacific Northwest apple orchards
TLDR
Data obtained from commercial sites provide circumstantial evidence for the effectiveness of well-timed CpGV applications against CM outbreaks, and first generation larvae were targeted beginning at egg hatch and treated areas monitored, fruit damage during the second larval generation was reduced or eliminated. Expand
Effect of Temperature on Long-Term Storage of Codling Moth Granulovirus Formulations
TLDR
The information reported in this study should be useful to growers and commercial suppliers for avoiding decreases in CpGV potency due to improper storage conditions. Expand
Codling moth granulovirus: a comprehensive review
TLDR
A comprehensive review of the CpGV literature and the role of the virus in integrated pest management is presented. Expand
The Role of Formulation Additives in Increasing the Potency of Cydia pomonella Granulovirus for Codling Moth Larvae, in Laboratory and Field Experiments
TLDR
These studies clearly demonstrate that major biological improvements in CpGV performance can be achieved by the incorporation of formulation additives, including molasses and several other compounds, that probably function as attractants and/or feeding stimulants for codling moth larvae. Expand
Genetic Structure of Cydia pomonella Granulovirus Isolates and their Potential in Overcoming Resistance in Codling Moth

  • 2019
TLDR
The potential of recently collected isolates of CpGV from northwest China to infect susceptible and resistant CM colonies is elucidated and the stability and restoration of type I resistance in laboratory rearing by mass-crossing and selection is studied. Expand
Effect of feeding stimulants on the insecticidal properties of Pieris brassicae granulovirus (PbGV) against Pieris brassicae
Feeding stimulants (phagostimulants) increase the food uptake by the host insect larvae and thereby play a vital role in enhancing overall activity of insect viruses formulated as biopesticides. AExpand

Death of Cydia pomonella larvae and damage to apple fruit, after field application of codling moth granulosis virus
TLDR
In field experiments, larvae of codling moth Cydia pomonella (L.) rarely acquired granulosis virus on hatching from the egg, but picked up most later, on the tree surface, where little feeding damage by first‐ and sometimes second‐instar larvae was seen. Expand

TLDR
The widespread development of strains of codling moth multi-resistant to insecticides and the desire to reduce dependence on pesticides have improved the commercial prospects of CpGV and use is likely to increase. Expand

TLDR
Bioassays with first, second, third, and fourth-instar larvae of Pieris brassicae and P. rapae revealed a marked difference in susceptibility between instars and between species. Expand

TLDR
It is demonstrated that neonate larvae of the pea moth, Cydia nigricana, are susceptible to infection with a granulosis virus (CpGV) isolated from the codling moth,Cydia pomonella. Expand
