Aphids can cause direct feeding damage and can also spot foliage and fruits with the honeydew they secrete. The honeydew acts as a medium for fungal growth, potentially leaving fruit and foliage smutted and black. Before making decisions to treat for aphid infestations, know the levels of aphid predators in the orchard and the tolerance of the host species to aphid injury. Feeding by lady beetles, lacewing larvae, syrphid and cecido-myiid fly larvae, wasps and true bugs can contribute to aphid control. Aphids typically can be found within curled leaves. Continued feeding will cause leaves to turn yellow, wilt and drop.
