GBM flight periods can be monitored using commercially available pheromone traps Figure 8. If possible, removal of wild grapevines near the vineyard will decrease potential reservoir sites. However, trap data are not used for timing of spray applications due to ambiguity concerning correlation of capture numbers and berry injury levels. Some degree of grape berry moth control is possible by burning or burying the leaves where pupae over-winter. The second generation larvae burrow into the grape berry and feed internally, which can be more damaging than the first generation.
