Pre-bloom feeding deforms blossoms and leaves, reducing fruit set or weakening the fruit so it is more susceptible to frost and temperature stresses. Thrips also spoil fruit finish by rasping the surface while feeding and by puncturing the fruit while laying eggs.
Feeding damage is usually more severe on stone fruits than on apples. On stone fruits, feeding causes scars similar to frost injury. On apples, feeding damage is usually only one cell deep on the fruit. When the fruit is damaged early in the season, it is russeted at harvest.
The major damage on apples is due to egg-laying punctures that cause a condition called pansy spot, a whitish discolored area shaped like the petals of a pansy surrounding a small scar where the egg was laid. On dark red apples, the pansy spot is usually covered with color at harvest, but yellow, pink and green varieties will still be discolored at harvest.
