Resistance of codling moth against Cydia pomonella granulovirus (CpGV) products has
alarmed growers, extension services, the CpGV producers and the scientific community.
During the last two years many activities were initiated in Germany and in Europe to
understand this phenomenon and to overcome this problem. Meanwhile, first important
results about the distribution, mode of inheritance and the efficacy of novel CpGV isolates
overcoming CpGV resistance became available. This contribution will provide an overview
about the different developments and the progress made towards an improvement of
CpGV application in the future
