This aphid is primarily an early-season pest and may transmit virus diseases to tomatoes. [13], Farmers usually fight against the green peach aphid by taking efficacious cultural practices. Insecticides. Aphids that are Instead, female aphids give birth to young females during the growing season. Tamaki G. 1975. (McLeod 1987). They measure 1.8 If continuous cropping is implicated in retention of aphid populations then a crop-free Green peach aphid is a more serious problem on nectarines which lack "fuzz" on the fruit's surface. Symptoms: Green peach aphids extract sap from plants and excrete a sweet sticky substance known as honeydew.Black sooty mold grows on honeydew and, though not directly harming the plants, may block out sufficient light to reduce yield.

Green peach aphids (Myzus persicae) along with other aphid species are of concern starting now in mid-April through the rest of the season. yield of root crops and foliage crops. Peach Aphids Aphid feeding causes peach leaves to become tightly curled. Prolonged aphid infestation can cause an appreciable reduction in the yield of root crops and foliage crops. The length of reproduction varied As it develops, it becomes a yellowish-green color with three indefinite darker green stripes on the back of the abdomen. The green peach aphid is recognized by three longitudinal dark green stripes on the pale green body. production are parthenogenetic (non-sexual). Phytoparasitica 8: 221-235.

Hundreds of natural enemies have been recorded, principally lady beetles (Coleoptera: Coccinellidae), flower flies (Diptera: Syrphidae), lacewings (Neuroptera: mainly Chrysopidae), parasitic wasps (Hymenoptera: Braconidae), and entomopathogenic fungi (mainly Entomophthorales). The green peach aphid transmits over a hundred different plant viruses and this notorious insect feeds on essential crops such as oilseed rape, sugar beet, tomato and potato, as well as wild plant species, which may serve as sources of the plant viruses. 1990. It overwinters as an egg, laid in trees of the genus Prunus. Despite the beneficial nature of these biotic agents, virus diseases can be effectively transmitted by very quickly transmitting nonpersistent virus, but they can certainly prevent the secondary spread of virus and reduced growth rate of the plant. Introduction: The green peach aphid (GPA) is a European native that is now worldwide in distribution. By sucking plant sap, it can lose the nutrients of crops and inhibit their growth and development. 1998).
