MALB adults are a pest of autumn ripening crops. In the vineyard, grape clusters that have been injured due to physiological splitting, yellowjackets or birds are an attractive option for MALB. The proportion of injured berries increases in the 2-3 weeks prior to harvest offering accessible feeding sites for MALB populations that are searching for fat and sugar reserves.
