Dioecious holocyclic.

Host plants

Primary hosts: Prunus cerasus (cherry) and rarely on other Prunus.

Agronomic impact

M. cerasi causes serious damage to young nursery trees and plants. Its presence leads to severe malformation of young shoots (photo) and strong crinkling of leaves.
The honeydew emitted induces scorching and necroses on leaf blades.
If infestations are severe, the ends of shoots wither and die, and fruit growth and maturation are held back.
