Summary

Insect-specific baculoviruses are increasingly used as biocontrol agents of lepidopteran pests in agriculture and forestry, and thy have been previously regarded as robust to resistance development by the insects. However, in more than a dozen cases of field resistance of codling moth Cydia pomonella to commercially applied C. pomonella granulovirus (CpGV) in German orchards, resistance ratios exceed 1000. The rapid emergence of resistance is facilitated by sex-linkage and concentration dependant dominance of the major resistance gene and genetic uniformity of the virus. When the gene is fixed, resistance levels approach 100.000-fold. Our findings highlight the need for development of resistance management strategies for baculoviruses.
