Mealy Bugs

These look like mealy bugs on the stem and fruits, a common pest and found in great numbers this year in your region on many different plants. You can spray the tree with soapy water to get rid of them while the fruit ripens, but you will probably see them again. If the infestation is persistent there are commercial sprays available at garden centers for this, but confirm the problem with a horticulturist at your local garden center and follow their recommended control. Usually the label will call for 3 sprays made 8 days apart to break up the life cycle, but make sure it is formulated for fruit trees. Next winter, use a horticultural oil spray while the leaves are off the tree – spray trunk and branches after pruning.
