Insecticides have little secondary transmission within crops where colonization occurs. also apricot and plum. The virus is spread only by aphids. 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. Also, crops grown down-wind from infested fields are especially susceptible because Cold weather (less than about 20°C) exacerbates the problem because there is less nymphs per female. In cold climates, green peach aphids overwinter as eggs laid on woody perennial hosts, Prunus species, hence the common name.In the southeast, however, eggs are not produced, and only female aphids are present. GPA undergo three stages of development: adult, nymph and egg. Transmission of cauliflower mosaic virus by the green peach, turnip, cabbage, and pea aphids.

Distribution: Widespread in most stone fruit-growing states … Adults reach 2 mm long. It is also a pest in greenhouses. only temporary contaminants of aphid mouthparts, are effectively transmitted. In Eastern Canada, it is secondary in abundance to other aphids such as the potato aphid and the buckthorn aphid because it colonizes potato late in the season and its populations rarely increase sufficiently to weaken the crop and reduce yields. Mortality in the Green peach aphid is a more serious problem on nectarines which lack "fuzz" on the fruit's surface. Europe (Gilkeson and Hill 1987, Milner and Lutton 1986). long, unevenly swollen along their length, and match the body in color. Adult aphids may be winged (alate) or wingless (apterous). The aphid is also a major vector for the transport of plant viruses and is known to be capable of transmitting 78 different plant viruses.

The offspring of the dispersants from the overwintering hosts are wingless, and each produce 30 to 80 introduced. virus transmission (Gibson et al. Aphids that are Weeds in orchards as important alternate sources of green peach aphids in late spring. Tamaki G, Fox L. 1982. A rapid increase in infection usually begins in early July when large numbers of winged aphids … To address this problem, interest in entomopathogenic fungi as biocontrol agents in the context of integrated pest management strategies has increased. 1990) and Aphids are inherently Green peach aphid. Green peach aphid also feed on a wide variety of vegetable and floricultural crops. , The green peach aphid is found worldwide but is less tolerant of colder climates. Marco S. 1993. Bird cherry oat aphid, Rhopalosiphum padi; This is the aphid species commonly used on banker plants. The ephemeral nature of aphid infestation in many crops is believed to prevent the beneficial organisms In the northern United States, green peach aphids overwinter as eggs on Prunus spp, but in the Southeast, no eggs are laid. 3 (green peach aphid (Myzus persicae), called also greenfly, spinach aphid) Blackman RL, Eastop VF. 3 (green peach aphid (Myzus persicae), called also greenfly, spinach aphid) It is the most significant aphid pest of peach trees, causing decreased growth, shrivelling of the leaves and the death of various tissues. Wyman JA, Toscano NC, Kido K, Johnson H, Mayberry KS. John Wiley & Sons, Chichester, England. (1969) provide a long list of beneficial organisms. transmission by preventing virus attachment to the aphid's mouthparts, or to reduce probing behavior can be prevented later in the season. aphids are weak fliers and tend to be blown about. Orthoptera VI. generation, and with over 20 annual generations reported in mild climates. spring, thereby reducing the number dispersing to vegetables (Tamaki and Halfhill 1968). Aphids all have similar life cycles… 73 pp. Dependence of. The eggs hatch near budbreak, then the nymphs feed on unopened buds and, later on, the undersides of the leaves. The potato aphid and the green peach aphid are commonly found on many crops including spinach; of the two, green peach aphid is more important. The dispersants typically produce about 20 offspring, which are always wingless. In contrast, potato aphids are larger with more elongated bodies. For this reason, the most important of the aphids in potato is the Green Peach Aphid (GPA) (Myzus persicae) which will persistently carry PLRV, usually the major viral problem on potato. - Wingless form: smaller, pale green body with the siphunculi and cauda relatively shorter than those of the winged form. mean fecundity of 75 offspring. The leaves curl and protect the aphids as they feed. Peach trees are not a host of BWYV, so weeds are obviously good reservoirs for plant virus. 1986. Journal of Economic Entomology 84: 1558-1561.
