Eriosoma lanigerum, commonly known as woolly apple aphid, is a pest that poses a serious threat to apple trees and other fruit-bearing plants. This insect feeds on plant sap, causing stunted growth, curled leaves, and reduced fruit quality. There are a few synonyms that can be used to refer to Eriosoma lanigerum, including the American blight aphid, the woolly apple aphid, and the woolly elm aphid. While these terms all refer to the same insect species, they may be more commonly used in certain regions or contexts. Agricultural experts and pest control professionals often rely on accurate scientific terminology to identify and manage harmful pests.
