Resistance of codling moth against Cydia pomonella granulovirus (CpGV): State of knowledge
Cydia pomonella granulovirus (CpGV) based biocontrol agents are highly effective and environmentally benign control measures for codling moth (CM). In recent years, CpGV has become a corner stone for CM control both in the organic and integrated production of apple and pears. In 2005, first reports on CM populations with a dramatically decreased susceptibility to CpGV products were published. S...
متن کاملNew method for testing solar sensitivity of commercial formulations of the granulovirus of codling moth (Cydia pomonella, Tortricidae: Lepidoptera).
A method for screening codling moth granulovirus (CpGV) formulation sensitivity to sunlight using specially prepared half apples and a solar simulator is described. The half apple preparation allows an even coverage of virus over the surface of the fruit that would not be possible using whole apples. Leaves and artificial medium were not usable for extended periods of exposure in the solar simu...
متن کاملThe complete sequence of the Cydia pomonella granulovirus genome.
The nucleotide sequence of the DNA genome of Cydia pomonella granulovirus (CpGV) was determined and analysed. The genome is composed of 123500 bp and has a G+C content of 45.2%. It contains 143 ORFs of 150 nucleotides or more that show minimal overlap. One-hundred-and-eighteen (82.5%) of these putative genes are homologous to genes previously identified in other baculoviruses. Among them, 73 ar...
متن کاملIncidence and transmission of a granulovirus in a large codling moth [Cydia pomonella L. (Lepidoptera: Tortricidae)] rearing facility.
Incidences of potential per os Cydia pomonella granulovirus (CpGV) transmission within a large codling moth colony were identified. CpGV was detected in the water which is used to wash egg sheets. When pre-neonates were extracted from eggs prior to emergence and tested for the presence of CpGV, 40% were found to carry amounts of CpGV detectable by a polymerase chain reaction (PCR) assay, sugges...
متن کاملWorldwide variability of insecticide resistance mechanisms in the codling moth, Cydia pomonella L. (Lepidoptera: Tortricidae).
The activity of detoxifying enzymes (glutathione-S-transferases (GST), mixed-function oxidases (MFO), and esterases (EST)) and the presence of insensitive variants of target proteins (sodium channel and acetylcholinesterase) were examined in individual male and female codling moths. Twenty-nine populations from 11 countries and two laboratory strains were examined. Populations were classified a...
