Aphidinae: Aphidini

Common name(s)

Mealy plum aphid


Apterae are small to medium-sized, body rather elongate, pale-green, mottled with darker green, always covered with white waxy meal. Colonies are found on the undersurface of leaves. Infested leaves do not curl. Both alatae and apterae have green abdomen with white wax patches on each segment. Dark pink aphids with similar wax coating are found in the same colony.

Antennae 6-segmented, shorter than body, in apterae brownish from apical half of segment V onwards, rest pale, in alatae brown, darker from apical half of segment III onwards. Processus terminalis three times longer than the base of segment VI. Cauda almost twice as long as siphunculi, which gives the aphid an elongate appearance. Siphunculi slender without flange.


Cosmopolitan (Europe, the Mediterranean region, Middle East, Central Asia, Pakistan, China). India: Bihar, Himachal Pradesh, Karnataka, Manipur, Meghalaya, Sikkim, Tamil Nadu, Uttar Pradesh, West Bengal.
