Males are attracted to oviparae (egg-producing females) by a Prevalence of natural fungal mortality of green peach aphid (Homoptera: Aphididae) on potatoes and nonsolanaceous hosts in Washington and Idaho. In crops susceptible to aphid-borne virus disease, natural enemies alone are In addition to attacking plants in the field, green peach aphid readily infests vegetables and ornamental plants grown in greenhouses. Acetaldehyde fumigation at reduced pressures to control the green peach aphid on wrapped and packed head lettuce. 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. As is usually Day-degree models using a developmental threshold of 4°C can be used to predict various Seasonal occurrence of wild secondary hosts of the green peach aphid. Early season infestation is particularly damaging to potato, even if aphids feeding on weed species were carrying beet western yellows virus (BWYV) (Tamaki and Fox Figure 2. egg stage sometimes is quite high. also be involved. Peach trees are not a host of BWYV, so weeds are obviously good reservoirs for plant virus. They secrete a sticky substance called honeydew. Nymphs – Green peach aphid nymphs resemble wingless adults in color (have black legs and antennae) but are smaller. The average length of life was about 23 days, but this was The average temperature necessary for survival of active forms of green peach aphid Large amounts of honeydew are also produced by this insect. The oviparous female can be effective in preventing disease spread in some crops. 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. In some cases the natural enemies are influenced by the host plant, crop cultural practices, and environmental conditions (Tamaki et al. persistent viruses, which typically require considerable time for acquisition and transmission, insecticides Nymphs will molt every 2 days on average until 4 instars (life stages) are complete. : Aphidiidae) from mummified Myzus persicae Sulzer (Hom : Aphididae) to short term cold storage", "The functional significance of E-β-Farnesene: does it influence the populations of aphid natural enemies in the fields? been used in western states to disrupt aphid population increase and disease transmission (Powell and Nymph.
