Green melon and black cowpea aphids are among several sap-consuming pests that attack bougainvilleas. These flat, oval insects typically congregate on tender new stems and foliage. They inject toxins into the leaves while feeding with their tissue-piercing mouthparts. The resulting damage, or phytotoxemia, includes curled, yellowing distorted leaves that fall prematurely. The pests also secrete honeydew, a gluelike, carbohydrate-rich waste that covers the leaves, branches and surrounding surfaces, and feeds sooty mold fungi. The black, powdery mold may block sunlight from reaching the foliage, reducing photosynthesis and weakening the plants.

Get rid of infested foliage and treat the rest with a natural or other insecticide. Scale insects, meanwhile, can be scraped off--an advisable treatment, since they are pesticide resistant.
