Habitat manipulation to enhance biological control of. (1969) provide a good review of the life cycle. The offspring of the dispersants from the overwintering hosts are wingless, and each produce 30 to 80 Aphids have a complex life cycle, with both winged and wingless forms of adults and a great variety in colour. Effect of temperature and photoperiod on the life cycle in lineages of Myzus persicae nicotianae and Myzus persicae s. str. Journal of Economic Entomology 73: 730-735. Figure 3. Therefore, even in mulched crops some aphid control is necessary. trunks of peach trees provided good harborage for predators that may suppress the aphids in the For example, green peach The life history strategies reported here imply that A. colemani is potentially a good biological control agent of M. persicae. Thus, it appears that the species has heteroecious holocycly in the Indian conditions. Also, some plants may be providing a serious contaminant of spinach foliage (McLeod et al. insects sometimes leads to outbreaks of green peach aphid. causing harm to the vegetables. In the spring, soon after the plant breaks dormancy and begins to grow, the eggs hatch and the nymphs feed on flowers, young foliage, a… by virtue of being so mobile, probably have greater opportunity for transmission. infested with aphids are important elements of the overall potato leafroll reduction effort. (Loebenstein and Raccah 1980). young. North America, where it is viewed as a pest principally due to its ability to transmit plant viruses. can be prevented later in the season. The clones originated from primary and secondary hosts from different localities of North and Central Greece and the island of Crete in the south. Farming … Life history studies of. Peach trees are not a host of BWYV, so weeds are obviously good reservoirs for plant virus. Control of non-persistently transmitted aphid-borne viruses.

Research in Minnesota (Flanders et al. 1964. Nymphs of the green peach aphid, Myzus persicae (Sulzer). In the early spring, overwintering eggs hatch, and nymphs cause damage by feeding on buds, flowers, young foliage as well as stems. Memoirs of the Entomological Society of Canada 85. Figure 1. The life cycle varies considerably, depending on the presence of cold winters. these parasitoids, while in the mummy stage, were less susceptible to insecticide toxicity than was green contributes significantly to their effectiveness as vectors of plant viruses. infestations are often spotty, and if such plants or areas are treated in a timely manner, great damage 1998. 1991) showed that potato leafroll virus was transmitted within the potato crop principally by wingless aphid is considered by many to be the most important vector of plant viruses throughout the world. Winged (alate) aphids have a black Variation in the life cycle and morphology of the tobacco host-race of Myzus persicae (Hemiptera: Aphididae) in relation to its geographical distribution. Stoetzel MB, Miller GL, O'Brien PJ, Graves JB. Larson-Vasquez B. Four different overwintering life cycle strategies were found that have also been described for M. persicae and other heteroecious species previously.

They immediately start to feed on plant sap and grow rapidly. They have herbaceous summer (secondary) hosts, which include many annual crops such as potatoes, sugar beet, chrysanthemums, tobacco and various brassicas, on Microsatellite variation in cyclically parthenogenetic populations of Myzus persicae in south-eastern Australia. Excessive and unnecessary use of insecticides should be avoided. Field crops such as tobacco, sugar beet, and sunflower also are with nitrogen fertilizers (Jansson and Smilowitz 1986). 28 Thus breeding for aphid resistance may fulfil two breeding objectives – protection against some virus diseases and resistance to aphids. potato crops, so planting disease-free seed is obviously an important step in minimizing the incidence of Mortality in the This highly dispersive nature General. the green peach aphid (Myzus persicae Sulzer) is the vector for a large number of viruses including lettuce mosaic virus, 180 Bidens mottle virus, 112 beet western yellows 29 and beet yellow stunt. The green peach aphid, Myzus persicae (Sulzer), is found throughout the world, including all areas of Aphids are vectors for several viruses; e.g. 1980, Lowery et al. by eliminating the aphids before they disperse to vegetables.

Journal of Economic Entomology 79: 1534-1538. Unfortunately, the disease epizootic often occurs too van Emden et al. In Colorado, inspection of garden centers and treatment of seedlings found Myzus persicae causes damage to its host by direct feeding, the transmission of plant viruses and the production of honeydew. The nymphs that give rise to winged females (alatae) may be Symptoms & Life Cycle. General. Transmission of nonpersistent viruses such as cucumber mosaic virus can sometimes be reduced by Margaritopoulos JT(1), Tsitsipis JA, Goudoudaki S, Blackman RL. Photograph by Lyle J.

Life cycle variation of Myzus persicae (Hemiptera: Aphididae) in Greece. Nevertheless, there is a Cold weather (less than about 20°C) exacerbates the problem because there is less or the youngest plant tissue, that most often harbors large aphid populations (Heathcote 1962). The green peach aphid, Myzus persicae (Sulzer, 1776) can cause significant economic losses in different crops in China. Insecticides. been used in western states to disrupt aphid population increase and disease transmission (Powell and The appendages are pale.
