Rose (Rosa)-Rose stem miner

Marmara spp.

Pest description and damage Larvae of this leaf- and twig-mining moth make sinuous, serpentine mines across the undersides of leaves. Where they cut through veins, the distal portion of the leaf may fade in color. Although damage is unsightly on individual leaves, they do not affect the long-term health or aesthetic quality of the plant.

Management-cultural control

If mines detract from the plant's appearance, prune or pick off and destroy infested leaves and canes. Rose stem miner is rarely a serious problem.
