Some D. suzukii were detected in the fruit in commercial fields prior to the final harvest, but none of the fields that were harvested experienced any fruit rejections or downgrades. Since the presence of D. suzukii in fruit in this study was measured by rearing adult flies out of the fruit, it is possible that the flies present in the fruit
were at a life stage (eggs or young larvae) not detectable through standard sampling methods. Even with the spray programs in place at the fields sampled for this study, the presence of some larvae in the fruit near harvest underscores the need for growers to be
vigilant until final harvest. It also highlights the unsustainability of current management practices and the necessity of non-chemical control measures for this pest, especially for organic growers where the limited insecticide options make for a greater chance of resistance developing over the years.
