Damage: Several species of aphids colonize blueberry bushes. However, this is the most important species. Aphids spread Blueberry scorch virus, but rarely cause direct crop damage. Aphids secrete sticky honeydew which can accumulate on leaves and fruit. Black sooty mould can develop on the honeydew.
Insect: Nymphs and wingless adults are small, 1-2 mm long, yellow, green, orange, or pink. Winged aphids are usually black and 2-3 mm long. Aphids are found on the underside of leaves and on new shoot tips, from March to September. The first generation of winged aphids emerges in early May. Aphid populations are highest in June and July. They overwinter as eggs on blueberry plants.
