Detailing the physical features, habits, territorial reach and other identifying qualities of the Oleander Aphids. The first sighting of a yellow-orange cluster of Oleander Aphids should put a gardener on the defensive. They feed on the plant juices of oleander, milkweed, butterfly weed, and wax plants - all popular plants in homes and butterfly gardens. Quick to reproduce during their short lives, Oleander Aphids need little time to infest a plant.
Oleanders are a popular ornamental flowering plant in southeastern states like Florida. Plant nurseries can lose product and profit because of an infestation. The ends of branches can deform and and wilt as a result of this constant feeding.
Other plants near infested ones are also at risk because 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 insects needed to pollinate flowers. Taxonomic Hierarchy.

Description Back to Top It is thought that the oleander aphid is an obligate parthenogenetic species; thus the adult aphids are all female and males do not occur in the wild. Adult females may be winged or wingless. The winged adult females alata are yellow and black with dark wing veins while the wingless forms apterae are yellow with black cornicles, antennae, legs, and cauda tip of abdomen. Nymphs are similar to apterae in appearance except that they are smaller. Size ranges from 1. Figure 1.
