The green peach aphid has a wide range of host plants , including peaches, vegetables, and ornamental crops (flowering and bedding plants including chrysanthemums). The green peach aphid, Myzus persicae(Sulzer), is found throughout the world, including all areas of North America, where it is viewed as a pest principally due to its ability to transmit plant viruses. The green peach aphid transmits a number of destructive viruses in pepper including pepper potyviruses and cucumber mosaic cucumovirus. In summer it moves to other hosts, which include a wide range of weeds and commercial vegetable crops. Life History The green peach aphid Myzus persicae, a notorious phloem-feeding hemipteran pest, colonizes more than 400 different plant species from over 50 families (Blackman and Eastop, 2000), and is capable of transmitting more than 100 plant viruses.This causes enormous reductions in crop yield, both through direct feeding and by transmission of viruses (Beemster and De Bokx, 1987). Copyright © 2008 Society of Chemical Industry. Although Canada plum is endemic along the southern border of Canada from Manitoba to New Brunswick, the green peach aphid rarely overwinters successfully on this host in New Brunswick. The green peach aphid gives birth to live young without mating during the growing season. Interestingly, this aphid uses the rose canes in the fall and hatch in the spring into pink and green aphids that feed on rose buds and young leaves. The green peach aphid is the most important vector of potato leafroll and it is an effective vector of potato virus A, potato virus S and potato virus Y. Pest Management In addition to attacking plants in the field, green peach aphid readily infests vegetables and ornamental plants grown in greenhouses. In addition, it can also damage the plant by sucking plant sap. The green peach aphid is recognized by three longitudinal dark green stripes on the pale green body. Cultural Practices - To prevent or reduce the spread of virus diseases or to eliminate infection, growers should plant only certified seed, rogue early and topkill as soon as possible after aphid flights begin. The body has cornicles that are highly swollen toward the tips, and the bases of the antennae have prominent, inwardly directed tubercles. Education and Early Childhood Development, Post-Secondary Education, Training and Labour. Adults may be winged or wingless. Monitoring - The green peach aphid is usually located on the lower leaves of potato. Geographical distribution: Cosmopolitan. Both Aphidius colemani (APHIDIUSforce C) and Aphidius ervi (APHIDIUSforce E) are parasitoid wasps that will attack many common species of aphids. The life cycle of green peach aphid varies considerably, and largely depends on winter temperatures. For instance, Green Peach Aphids overwinter as eggs on peach and related trees but in spring they move to various weeds and agricultural crops, and then still later they move onto potato crops, only in the fall returning to peach and related trees. Rusty plum aphid (Hysteroneura setariae). The NIa-Pro protein of Turnip mosaic virus improves growth and reproduction of the aphid vector, Myzus persicae (green peach aphid). Pest description and crop damage The black bean aphid is a dark-bodied aphid, 0.0625 inch long, that sporadically reaches damaging levels, most often late in the season. Damaging levels are characterized by large numbers of aphids found on the underside of leaves. Adults may survive in storage areas. Green peach aphid (Myzus persicae) . Nymphs – Green peach aphid nymphs resemble wingless adults in color (have black legs and antennae) but are smaller. The green peach aphid, Myzus persicae(Sulzer), is found throughout the world, including all areas of North America, where it is viewed as a pest principally due to its ability to transmit plant viruses. Asia, Africa, North, South and Central America, the Caribbean, Europe, Oceania. Infestations usually occur as scattered hot spots or along edges rather than uniformly across the entire field. Here is a brief chronological overview. The body of the winged form is much slimmer with large oval shaped clear wings. In addition to attacking plants in the field, green peach aphid readily infests vegetables and ornamental plants grown in greenhouses. In areas where early colonization from overwintering hosts or greenhouse colonies are likely, a systemic insecticide at planting will be effective for seven weeks or longer. Worldwide. Adults – Wingless forms are light green to yellow. 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. Generic Life Cycle. In general, determination of the need for control is based on the occurrence of sudden and significant increases in the abundance of the green peach aphid on potato plants or in monitoring traps. A. ervi attacks “larger” species such as Potato Aphid (Macrosiphum euphorbiae) and Foxglove Aphid (Aulacorthum solani). feeding from host plants, eleven Myzus persicae (green peach aphid) salivary proteins and the GroEL protein of Buchnera aphidicola, a bacterial endosymbiont of this aphid species, were expressed transiently in Nicotiana tabacum (tobacco). It is considered to be a pest nearly everywhere, often due to its ability to transmit plant viruses. Green peach aphid can seriously curl and deform the emerging foliage of host plants in spring.
