Background: It is generally assumed that short-term population dynamics are too slow to be influenced by evolution. Question: Can evolution occurring within only weeks (four to five generations) impact concurrent population dynamics? Organism: Green peach aphid (Myzus persicae) growing on an undomesticated host (Hirschfeldia incana). Aphid clones were collected from a single wild population. Si...

The green peach aphid, Myzus persicae (Sulzer), is a major insect pest of many agronomic and horticultural crops and is distributed worldwide. Aphid management is often based on application of insecticides. However, the aphid is now resistant to many of these and much interest has recently developed in identification of novel alternative insecticides. Venom isolated from the red imported fire a...

Aphids are sap-sucking insects that mainly attack shoots and young leaves of peach trees and many other plant species; however, knowledge of the Brazilian aphid fauna is scant. The objective of this study was to identify aphid species collected in peach orchards (Prunus persica Batsch) and to determine their faunal indices for occurrence and dominance. The experiment was conducted from July 200...

The phloem provides a unique niche for several organisms. Aphids are a large group of Hemipteran insects that utilize stylets present in their mouthparts to pierce sieve elements and drink large volumes of phloem sap. In addition, many aphids also vector viral diseases. Myzus persicae, commonly known as the green peach aphid (GPA), is an important pest of a large variety of plants that includes...

ABSTRACT Peaches and nectarines are frequently attacked by the green peach aphid Myzus persicae (Sulzer), with significant negative impacts on fruit production. The genetic variability of resistance to this aphid among commercial cultivars of Prunus persica (L.) Batsch and Prunus persica variety nectarina was evaluated in this study. In total, 16 cultivars of P. persica were selected to evaluat...

BACKGROUND Virus-induced deterrence to aphid feeding is believed to promote plant virus transmission by encouraging migration of virus-bearing insects away from infected plants. We investigated the effects of infection by an aphid-transmitted virus, cucumber mosaic virus (CMV), on the interaction of Arabidopsis thaliana, one of the natural hosts for CMV, with Myzus persicae (common names: 'peac...

the green peach aphid,myzuspersicae  (hem:aphididae) is a polyphagus aphid species that infects over 400 plants species belonging to 40 different families. the oenopia conglobata contaminata  (col.: coccinellidae) is one of the most important predator of orchard pests in iran. in this study, efficiency and predatory of this predatoron green peach aphid m.persicaewas evaluated under laboratory c...
