Molecular insights into arabidopsis response to Myzus persicae sulzer (green peach aphid)
Phloem-feeding insects like aphids feed on a variety of crop plants and limit plant productivity. In addition they are vectors for important plant viruses. Efforts to enhance plant resistance to aphids have been hampered by lack of sufficient understanding of mechanisms of plant defense against …

Effect of predators on population dynamics of green peach aphid on flue-cured tobacco in Virginia
The effects of indigenous predators on green peach aphid (GPA), Myzus persicae (Sulzer), populations on flue-cured tobacco were evaluated in 1985 and 1986. The most common GPA predators found on tobacco were convergent lady beetle (CLB) (Hippodamia convergens), syrphid flies, Geocoris spp., Jalysus …

Quantification of insecticide resistance in the tobacco-adapted form of the green peach aphid, Myzus persicae (Sulzer)(Hemiptera: Aphididae)
The tobacco-adapted form of the green peach aphid, Myzus persicae (Sulzer), is one of the most important insect pests of tobacco in the United States and around the world. Insecticides play a major role in controlling the aphid on tobacco because natural enemies usually fail to maintain its …

Factors affecting the population dynamics of the green peach aphid, Myzus persicae (Sulzer), on flue-cured tobacco in Virginia
The temperature-dependent development of red and green morphs of the green peach aphid, Myzus persicae (Sulzer), was compared on flue-cured tobacco, Nicotiana tabacum (L.), at moderate to high constant temperatures in the laboratory. The red morph was found to develop faster and reproduce more than …

Genetic analysis of resistance to Myzus persicae (Sulzer) in Nicotiana tabacum L.
Field experiments with the green peach aphid on tobacco were conducted at Blackstone, Virginia in 1983 and 1984. The objectives were to: 1) confirm and identify source materials resistant to the green peach aphid; 2) study the inheritance of aphid resistance; 3) verify heritability of resistant …

Potential of Pandora neoaphidis (Remaudière & Hennebert) Humber as a fungal pathogen for the control of tobacco aphid, Myzus nicotianae Blackman, on tobacco
The potential of Pandora neoaphidis (Remaudiére & Hennebert) Humber as a fungal pathogen for the control of the tobacco aphid, Myzus nicotianae Blackman, on tobacco was evaluated in a 4-year study between 1992 and 1995. The objectives of this study included determination of the seasonal incidence …

Isolation and characterization of a novel lectin gene, Allium triquetrum agglutin, conferring insecticidal properties against Myzus persicae
Myzus persicae, more commonly known as green peach aphid, is an important pest in agriculture. Each year it causes great losses to agricultural and horticultural plants. It feeds on sap in the phloem, the main transportation route for plant nutrients. It also transmits more than 100 plant viruses, …

Variability of the peanut mottle virus reaction in soybean (Glycine max)
… and to characterize the PMV strains using aphid transmission efficiency and serological relationships. Twelve PMV isolates were placed in five strain groups (P1-P5) based on symptom expression in the soybean cultivars Lee 68, York, and Virginia. Aphid transmission efficiency of the PMV …

Control of Turnip yellows virus: Assessing impact on oilseed rape quality traits and dissecting circulative transmission by aphids
… their genetic potential. TuYV is transmitted by aphids, sap-sucking hemipteroid insects, and the green peach aphid (GPA) is the predominant vector. TuYV can reduce oilseed rape yield by up to 26% in the UK and may also affect oil quality. Current control measures rely on insecticides; however, …

The application of novel mass spectrometric techniques for the analysis of volatile organic compounds in different environments
… persicae – Adalia bipunctata larvae (rapeseed – green peach aphid – two-spotted ladybird larvae) model system. Plant volatile emission was monitored using a PTR-MS and SRI-ToF-MS which enabled the better detection and identification of bVOCs than is possible using a traditional PTR-MS. Following …
