ENEMIES. The rosy leaf-curling aphid has the same enemies as the rosy apple aphid. In the case of the rosy leaf-curling aphid, however, the enemies are much more effective, as the rosy leaf-curling aphid does not have the same reproductive potential.

As far as possible, control measures should not be applied immediately, in order to give beneficials (predators and parasites) the possibility of self-regulation. Because the rosy leaf-curling aphid has a large number of enemies, this is easier than in the case of the rosy apple aphid.
