Black Cherry Aphid — Sour Cherry

Prunus cerasus L.

The black cherry aphid (Myzus cerasi) is a heteroecious pest that uses the sour cherry as a primary host for egg overwintering and the development of spring generations. It is characterized by infesting young leaves and shoot tips, causing them to deform and wither.

The black cherry aphid Myzus cerasi is a specialized oligophagous pest of stone fruit crops. The adult apterous individuals of this species are distinguished by a shiny black or dark brown body color and reach a length of 2.0–2.4 mm. During the summer period, the pest migrates to secondary hosts, primarily from the Rubiaceae, Scrophulariaceae, and Orobanchaceae families.

Insect colonies are localized on the underside of young leaves and on the tips of growing shoots. During the feeding process, the growth of the central leaf veins ceases, which leads to their spiraling, blackening, and subsequent withering. Damaged shoots become distorted, and sooty mold fungi develop on the aphid honeydew, often accompanied by ant activity.
