''C. pomonella'' has proved to be a problematic pest on several fruit trees, including apples and pears. The caterpillars burrow into the fruit, rendering it unfit for sale. Traditional insecticides are of limited use, as some strains have acquired resistance to several insecticides. CpGV has been shown to kill many of the larvae of ''C. pomonella'' in trials without having adverse effects on humans or other animals, thanks to the specific nature of the virus. The first CpGV strain, isolated in Mexico, has been commercially formulated into biological pesticides such as Madex (Andermatt Biocontrol AG), Carpovirusine (NPP/Arysta LifeScience) and Cyd-X (Certis). Due to the continued use of CpGV in the field, populations resistant to the Mexican strain of ''C. pomonella'' have been identified. New strains which are able to manage resistant codling moth populations have been developed. These strains are commercialized by BioTEPP inc. into Virosoft CP4, NPP/Arysta LifeScience into Carpovirusine Evo 2 and by Andermatt Biocontrol AG into Madex Max and Madex Plus.
