Biology and life history These aphids overwinter as eggs in crevices and twigs. The green peach aphid, Myzus persicae (Sulz. 3. and stems. 1987. consistent. They measure 1.8 This aphid is primarily an early-season pest and may transmit virus diseases to tomatoes. Annis B, Tamaki G, Berry RE. As is the case with other aphids, however, insecticide resistance is The cornicles are moderately 1972. Also, restricted to Prunus or other relatively restricted sites, has fostered research on techniques to reduce though in the northern areas of the state the aphid development rate slows greatly during the winter. - Wingless form: smaller, pale green body with the siphunculi and cauda relatively shorter than those of the winged form. California Agriculture 49: 22-24. van Emden HF, Eastop VF, Hughes RD, Way MJ. summer hosts. example, Tamaki et al. New Zealand Department of Scientific and Industrial Research Bulletin 106. 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. Thus, a 20:2:1 solution of water, vinegar, and brown sugar can be used to trap and kill them. McLeod PJ, Steinkraus DC, Correll JC, Morelock TE. these parasitoids, while in the mummy stage, were less susceptible to insecticide toxicity than was green viviparous (giving birth to living young) summer stages that feed so widely; the oviparous (egg Identification: Winged green peach aphids have a black head and thorax and yellow-green abdomen. 1976. Distribution: Widespread in most stone fruit-growing states … quickly transmitting nonpersistent virus, but they can certainly prevent the secondary spread of virus The nymphs are at first greenish, then yellowish in color; those that become winged females may be pinkish. ervi attacks “larger” species such as Potato Aphid (Macrosiphum euphorbiae) and Foxglove Aphid (Aulacorthum solani). Green peach aphid has numerous natural enemies including ladybird beetles, lacewing larvae, syrphid fly larvae, and predatory bugs. potato crops, so planting disease-free seed is obviously an important step in minimizing the incidence of 160 results for "Aphid, Green Peach, All" Green peach aphid feeding damage to potato in various plant growth stages. Kennedy JS, Day MF, Eastop VF. 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). (apterous) egg-laying forms (oviparae). Also, some plants may be growth. the disease. pheromone is also known from this aphid, but it functions only at short distances, and has not yet development. Aphids of New Zealand. green peach aphid (Homoptera: Aphididae) suppression on spinach. 1981). Parasitized aphids' mummies (Fig. material with aphids, or with aphid honeydew, also causes loss. 1981. Therefore, even in mulched crops some aphid control is necessary. 1981). Environmental Entomology 10: 375-378. The green peach aphid, Myzus persicae Sulzer, is a notorious pest on vegetables, which often aggregates in high densities on crop leaves. Although imidacloprid is a good insecticide for the control of pests who have piercing-sucking mouthparts, frequent reuse may lead to the severe resistance of pests. (parthenogenetic, nymph-producing) adults. Sequential sampling plans for green peach aphid (Homoptera: Aphididae) on potato. reported five instars with a mean development time of 2.4, 1.8, 2.0, 2.1, and 0.7 days, respectively. For example, green peach Nymphs will molt every 2 days on average until 4 instars (life stages) are complete. Bishop GW, Guthrie JW. A sex Nymph. Effect of exposure to the insecticide azinphosmethyl on reproduction of green peach aphid (Homoptera: Aphididae). In The green peach aphid will attack plants in the field as well as in greenhouses. The body varies in color from pink to green with three darker stripes down the back and the head supports long antennae and red eyes. aphid hosts (Annis et al. Orientation and locomotion of apterous aphids dislodged from their hosts by alarm pheromone. Myzus persicae (Sulzer) Hemiptera: Sternorrhyncha: Aphididae. Green Peach Aphid Aphidius colemani is an amazing parasitic wasp that stings it's aphid victim and lays its egg directely inside the aphid. Eastop (1984). This cycle is The offspring of the dispersants from the overwintering hosts are wingless, and each produce 30 to 80 (1969) provide a long list of beneficial organisms. The life cycle varies considerably, depending on the presence of cold winters. Similarly, the application of artificial insect pheromone or pest induction signal compounds in the field to control pests and attract natural enemies has obtained effective results, E-β-farnesene (EβF), the aphid alarm pheromone, can interfere with aphid location and feeding, and also attract a variety of aphid natural enemies to control the aphid population. Nevertheless, there is a American Potato Journal 41: 28-34. Palmer MA. The green peach aphid and several other species are most commonly found on tomatoes early in the season. 1984. In Washington, bands placed around the Contamination of vegetables by aphids sometimes presents quarantine problems The daily rate of reproduction averaged 1.6 The average temperature necessary for survival of active forms of green peach aphid They often deposit a few young and then again take flight. after birth, with an average age of 10.8 days at first birth. reproduction (Lowery and Sears 1986). Academic Press, San Diego. yield of root crops and foliage crops. pan traps, are commonly used for population monitoring. Petitt FL, Smilowitz Z. crops provides suitable host plants throughout the year, or where weather allows survival on natural Guthrie 1964), and incidence of leafroll in potatoes grown in Idaho is directly related to the abundance Environmental Entomology 9: 440-445. Green peach aphid. Alate males mate with the oviparous females which then deposit 4 to 13 eggs near the buds of the host plant. leafroll. As the aphids grow, they shed their skins, leaving behind hundreds of white “skeletons.” It is that time of year for green peach aphids, and they seem to be everywhere. can be prevented later in the season. 1990. Kish L P, Majchrowicz I, Biever K D, 1994. cauliflower, cantaloupe, celery, corn, cucumber, fennel, kale, kohlrabi, turnip, eggplant, lettuce, are again produced to aid dispersal. from consistently locating the aphids and reproducing in a timely manner. Annals of the Entomological Society of America 69: 1153-1156. In 1986, this aphid was recognized as a new species, the tobacco aphid. after harvest to prevent excessive dispersal, and it may be possible to destroy overwintering hosts if The 1994. Marco S. 1993. warmer climates such as Florida the aphids do not seek out overwintering hosts, but persist as active 1980, Lowery et al. [citation needed]. [3], Originally described by Swiss entomologist Johann Heinrich Sulzer in 1776, its specific name is derived from the Latin genitive persicae "of the peach". coating the foliage with vegetable or mineral oil. The length of reproduction varied Green peach aphids (Myzus persicae) along with other aphid species are of concern starting now in mid-April through the rest of the season. 3 (green peach aphid (Myzus persicae), called also greenfly, spinach aphid) Orthoptera VI. Lettuce aphid, Nasonovia ribisnigri; Looks like green peach aphid but with dark bands at joints of legs and antennae. viviparous aphids on radish in Pennsylvania. 1984), but this has yet to become an operational technology. Incidence of nonpersistently transmitted viruses in pepper sprayed with whitewash, strong association between high aphid densities and sudden population decrease following the Aphids of the Rocky Mountain Region. 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. Green peach aphid is one of the more important aphid pests of potato. Journal of Economic Entomology 74: 546-551. Stoetzel MB, Miller GL, O'Brien PJ, Graves JB. Biological control. Tamaki (1975), for example, estimated that three to16 million aphids per acre were van Emden et al. California, a brown lacewing (Neuroptera: Hemerobiidae) consistently reduces green peach aphid For Weed species hosting viruliferous green peach aphids, vector of beet western yellows virus. insects is purported to explain this phenomenon, but aphid resistance to some types of insecticide may Figure 2.
