Agronomic impact

D. plantaginea is the most devastating of the apple aphids owing to its high fecundity coupled with the early onset of its activity in spring.
Colonies induce strong rolling of young leaves (photo of damage on a young apple branch) followed by yellowing of the leaves.
Fruit becomes deformed following pre-flowering injections by the fundatrices.
Deformations persist even after aphids have left: shoots distorted, fruit scrawny and bumpy.
On the young shoots, the insect prevents crown formation and the year after a strong attack fewer flowers are produced.
