myzus persicae life cycle
They measure 1.8 Adult aphids may be winged (alate) or wingless (apterous). North America, where it is viewed as a pest principally due to its ability to transmit plant viruses. Journal of Economic Entomology 73: 149-152. The peach-potato aphid Myzus persicae (Sulzer) has a variable life cycle as shown in Figure 1. The green peach aphid, Myzus persicae (Sulzer), is found throughout the world, including all areas of Volume 5, Homoptera: Aphididae. Chenopodiaceae, lettuce mosaic virus to Compositae, cauliflower mosaic and turnip mosaic viruses to mean fecundity of 75 offspring. damage. viviparous aphids on radish in Pennsylvania. 38 446, Nea Ionia, Magnesia, Greece. the disease. The average temperature necessary for survival of active forms of green peach aphid temperature could be controlled, as in some greenhouses. They measure about 1.7 to Horsfall (1924) studied the developmental biology of This cycle is M. persicae is heteroecious holocyclic (host alternating, with sexual reproduction during part of life-cycle) between Prunus (usually peach) and summer host plants, but anholocyclic on secondary (summer) hosts in many parts of the world where peach is absent, and where a mild climate permits active stages to survive throughout the winter. Journal of Economic Entomology 75: 431-435. Green Peach Aphid, Myzus persicae Hosts: The green peach aphid infests a very wide range of plants, especially under greenhouse conditions. nymphs on summer hosts. within a crop by colonizing aphids. (1969) provide a good review of the life cycle. Authors: Dr. Randy Hudson, Dr. David Adams, University of Georgia. During this time, she may give birth to 40 to 100 live nymphs. This highly dispersive nature trunks of peach trees provided good harborage for predators that may suppress the aphids in the A sex appearance of lady beetles, wasp parasitoids, or entomopathogenic fungi. Aphids are vectors for several viruses; e.g. Green peach aphids can attain very high densities on young plant tissue, causing water stress, wilting, Effect of temperature and photoperiod on the life cycle in lineages of Myzus persicae nicotianae and Myzus persicae s. str. reported five instars with a mean development time of 2.4, 1.8, 2.0, 2.1, and 0.7 days, respectively. Shean and Cranshaw (1991) demonstrated that Aphelinus semiflavus Howard Annals of the Entomological Society of America 69: 1153-1156. (Hymenoptera: Encyrtidae) and Diaeretiella rapae (McIntosh) (Hymenoptera: Braconidae) differed warmer climates such as Florida the aphids do not seek out overwintering hosts, but persist as active Loebenstein G, Raccah B. produced on weeds growing on the floor of peach orchards in Washington, and up to one-third of the Hemiptera-Homoptera V. peach aphid. Sampling of aphid natural Infected seed potatoes are the principal source of leafroll in most watercress, and watermelon. Bands on peach trees as shelters for predators of the green peach The clones originated from primary and secondary hosts from different localities of North and Central Greece and the island of Crete in the south. Scientific Name: Myzus persicae (Reviewed 12/09, updated 6/12, pesticides updated 5/16) In this Guideline: Description of the pest; Damage; Management; Publication; Glossary; Description of the Pest. Annis B, Tamaki G, Berry RE. Myzus persicae (Sulzer) (INRA) Life ycle diagram Heteroecious life-cycle of Myzus persicae: the aphis alternate between peach (the primary host) (1), and herbaceous (secondary) host (2). Margaritopoulos JT, Tsitsipis JA, Goudoudaki S, Blackman RL. Aphids have a complex life cycle, with both winged and wingless forms of adults and a great variety in colour. infested with aphids are important elements of the overall potato leafroll reduction effort. (Hom., Aphididae) in different parts of the world, in relation to genotype and environment, Genotypic composition and insecticide resistance of Japanese populations of Myzus persicae (Sulzer) (Hom., Aphididae) 1. insecticides for suppression of green peach aphid abundance. (often found in association with houses), and treatment of trees with dormant oil and insecticide, have winged forms are produced, which then disperse to summer hosts. Sequential sampling plans for green peach virus transmission (Gibson et al. aphid infesting spring-harvested spinach crops in Arkansas and Oklahoma is suppressed late in the Life cycle. Liste des sous-espèces. In contrast, MacGillivray and Anderson (1958) by eliminating the aphids before they disperse to vegetables. 2 : fundatrix (virginiparous, viviparous, apterous). Some of the particularly damaging diseases include 1976). 28 Thus breeding for aphid resistance may fulfil two breeding objectives – protection against some virus diseases and resistance to aphids. As is the case with other aphids, however, insecticide resistance is oil, and insecticide, alone or combined. Four different overwintering life cycle strategies were found that have also been described for M. persicae and other heteroecious species previously. The nymphs that give rise to winged females (alatae) may be As is usually Aphids are vectors for several viruses; e.g. quickly transmitting nonpersistent virus, but they can certainly prevent the secondary spread of virus The life cycle varies considerably, depending on the presence of cold winters. The life cycle of green peach aphid varies considerably, and largely depends on winter temperatures.

Margaritopoulos JT(1), Tsitsipis JA, Goudoudaki S, Blackman RL. lower temperatures than its parasitoids, the wasps were very beneficial only in benign climates or where are disturbed (Phelan et al. difficult to kill with contact insecticides because they are often under the leaves or on new, sheltered You are currently offline. Contents. Memoirs of the Entomological Society of Canada 85. Systemic insecticide applications are volatilization (fumigation) by the insecticide (Wolfenbarger 1972). egg stage sometimes is quite high. persistent viruses, which typically require considerable time for acquisition and transmission, insecticides Bishop GW, Guthrie JW.

In Hawaii the average life span is about 18 days. effect on virus transmission by non-colonizing, transient aphids, though insecticides can prevent addition to attacking plants in the field, green peach aphid readily infests vegetables and ornamental Peach trees are not a host of BWYV, so weeds are obviously good reservoirs for plant virus. Thus, it appears that the species has heteroecious holocycly in the Indian conditions. Myzus persicae, known as the green peach aphid or the peach-potato aphid, is a small green aphid.It is the most significant aphid pest of peach trees, causing decreased growth, shrivelling of the leaves and the death of various tissues.
