Damage (Rosy apple aphid)

• First signs of damage are in early spring when outer rosette leaves of infested trusses show a slight yellowish discoloration before curling.
• As larger colonies develop, infested leaves are severely curled downward and distorted.
• They sometimes turn yellowish brown, but never red (red distorted leaves are caused by the rosy leaf curling aphid).
• Damaged fruits are often small, malformed with uneven, wrinkled and sometimes waxy skin and often develop a rosy colour.
• Sometimes, larger damaged fruits have sunken darker areas.
