Capitophorus elaeagni

Common oleaster aphid

Description

Capitophorus elaeagni, commonly known as the common oleaster aphid or artichoke aphid, is an oligophagous species in the family Aphididae. It primarily inhabits plants from the family Elaeagnaceae, such as Elaeagnus angustifolia, E. multiflora, and Hippophae rhamnoides during its primary host phase. During its secondary host phase, it alternates to various plants from the family Asteraceae, including thistles (Cirsium spp.) and daisies. The apterae are pale yellowish-green, measuring 1.4–2.5 mm, with dark-tipped siphunculi.

This aphid overwinters as eggs on the primary host and reproduces sexually in the autumn. Its feeding reduces plant vitality by extracting sap, causing curling and discoloration of leaves. Affected plants may also exhibit honeydew and subsequent sooty mold growth, reducing their aesthetic appeal. The species is distributed widely across temperate regions of Europe and other parts of the world.

Symptom

On infested plants, leaves are curled, discolored, and coated with sticky honeydew. Colonies of pale yellow-green aphids are concentrated on the undersides of leaves, often accompanied by sooty mold.
