They appear in spring on young shoots: they feed on the elaborate sap of the plant by pricking soft tissues. They are rapid haunts and the damage produced is mainly aesthetic, marked by deformations of the apical tissues and deposit of sticky sugary substance, produced as a waste of their metabolism. This can attract other insects such as ants and wasps and be the optimal substrate for the formation of the fumaggine. The aphid can also be a vector of viruses if nearby there are sick plants.

Azioni preventive: the best intervention to contain the development of aphids is the preventive use of a systemic product (Imidacloprid) that allows the plants to remain protected for a long time. This product is also useful against Tentredini.

Azioni curative: against aphids can be both used products based on natural or synthesis pyrethrum (deltamethrin), also called “felling-product”. Using natural photolabile pyrethrins, which are rapidly degraded from the environment, calls naturally antagonist insects (Coccinella, Crisope, Dittero sirfide, etc.) who control the population of aphids with minimal impact.
