Aphidinae is the largest of aphids (Aphididae), comprising at least 2,483 across 256 in two tribes: Macrosiphini (approximately three-quarters of species) and Aphidini. Members are distributed globally and include the majority of pests affecting crops and ornamental plants. Many species are of potyviruses, particularly in the genera Macrosiphum and Myzus. The subfamily exhibits remarkable morphological diversity in body shape and coloration, and possesses evolutionarily conserved odorant receptors for detecting (E)-β-farnesene, a key component.

Distribution

Members of Aphidinae occur in nearly every region of the world. Documented occurrences include: West Java, Indonesia; northern Iran (Alborz Province, Kerman Province, Tehran Province); China (northwestern and southwestern regions); Ukraine (Forest-Steppe zone, broad-leaved forest zone, mixed forest zone); Turkey (Adana and Hatay Provinces); New Zealand ( ); and Europe (including Serbia, France).

Life Cycle

Includes multiple morphs: fundatrix (founding stem mother), females (parthenogenetic summer ), viviparous females (winged morphs), females (sexual morphs producing ), and apterous males. Many exhibit alternation between a primary woody host (typically a tree) and secondary herbaceous hosts; others are , completing their entire on a single host type.

Human Relevance

Most pests on crops and ornamental plants belong to Aphidinae. Many are economically significant as direct plant feeders and as of potyviruses, particularly in the Macrosiphum and Myzus. Some members serve as for used in , including genera such as Lysiphlebus and Adialytus.
