Oleanders are a popular ornamental flowering plant in southeastern states, like Florida. Plant nurseries can lose product and profit because of an infestation. The aphid's presence ruins the beauty of the oleander because it creates a sticky 'honeydew' on the stems, which can eventually turn black with mold. Oleander Aphids use their mouthparts to poke into the plant stem and then syphon food juices, damaging the plant's health. The ends of the branches can deform and and wilt. Other plants near infested ones are also at risk. The aphids can spread a plant virus, further impacting nurseries or gardens. Natural predators of the Oleander Aphid include certain kinds of parasitic wasps, Lady Beetles, Lacewings and Hoverflies. Insecticide use to control aphid infestations is effective, but care must be taken in choosing one that will not also harm beneficial insect predators.
