In this section of the Vermont Apple Newsletter , a different arthropod or disease will be featured. They are brown in color with a white or yellow Y on the thorax.
Nymphs are green in color with black spots.
They become active in the spring and move to fruit trees as buds begin to open. They are most abundant and active in the orchard from green tip through petal fall. Buds or flowers which have been injured will abort or fail to develop normally. Early feeding on the fruit occurs later in the season and results in depressions which deepen as the fruit grows. Egg laying punctures are deeper and are most often found on the calyx end.
