Life cycles

Monoecious holocyclic.

Host plants   

Rosaceae, particularly Malus (apple) and Pyrus (pear) and to a lesser extent Cotoneaster, Crataegus.

Particular characteristics

A. pomi develops by forming sleeve-like colonies as illustrated here on young apple branch.

Agronomic impact

A. pomi causes blackening of leaves and shoots due to copious secretions of honeydew and development of sooty mould.

Under intense attack, leaves roll up transversally and crinkle which leads to arrested growth and desiccation of new shoots.
