Molecular insights into arabidopsis response to Myzus persicae sulzer (green peach aphid)
… Arabidopsis thaliana and the generalist aphid, Myzus persicae Sulzer (green peach aphid [GPA]), to study plant response to aphids. These studies have demonstrated an important role of premature leaf senescence in controlling aphid growth in Arabidopsis. Molecular and physiological studies …

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 …

Intraclonal Morphological Plasticity within the Myzus persicae (Sulzer) Complex Related to Host Plant and Temperature
… used life cycle and morphology to separate Myzus nicotianae Blackman, a tobacco-feeding species of aphid, from Myzus persicae (Sulzer). In the present study, the first objective was to investigate the influence of temperature and host plant on the morphology of M. nicotianae and M. persicae. …

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, …

Behavioural and physiological responses of myzus persicae to ultraviolet light for the development of new pest control technologies
… the population growth of the generalist aphid, Myzus persicae, on cabbage (Brassica oleracea) plants. These polytunnel field experiments established new hypotheses for the role of long-wavelength ultraviolet radiation as an environmental cue for damaging short-wavelength ultraviolet radiation. …

Quantification of insecticide resistance in the tobacco-adapted form of the green peach aphid, Myzus persicae (Sulzer)(Hemiptera: Aphididae)
… 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
… 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 the green morph at temperatures that …

Functional characterisation of aphid, Myzus persicae, nicotinic acetylcholine receptors and identification of a novel biogenic amine-gated ion channel from the honeybee, Apis mellifera
… two-electrode voltage clamp electrophysiology. Myzus persicae, the peach potato aphid, is a major global pest of multiple crop species. The nAChR subunits and several protein chaperones from Myzus persicae have been cloned. It was difficult to achieve robust and frequent expression of a nAChR …

Virus-induced effects on aphid-host interactions in Solanaceous plants
… on settling preference of two aphid species (Myzus persicae, a generalist, and Macrosiphum euphorbiae, a Solanaceous specialist) at 3, 9 and 21 days post-inoculation (dpi) and at 1 and 24 h following aphid release, using aphid free choice and trapping assays in light and dark conditions and …

Studies of Resistance to Aphids and Viruses in Arabidopsis thaliana and Capsicum annuum
… resistance to CMV infection and infestation by Myzus persicae, a vector that transmits CMV, were assessed. There were two parts to the project. In the first, the feasibility of using exogenous salicylic acid (SA) application to induce resistance to CMV infection in pepper (Capsicum annuum) …

The relationship of time of year, geographic location, insecticide exposure and the genotype of red and green morphs of the tobacco aphid, myzus nicotianae Blackman, in Virginia
… of red and green morphs of the tobacco aphid, Myzus nicotianae Blackman, on tobacco was investigated in Virginia in 1988 and 1989. Color morph and karyotype were found to be highly related. The translocated karyotype was associated with the red morphs and the normal karyotype was associated …

Aphids as vectors of peanut mottle virus
… of PMV such as Aphis craccivora (Koch) and Myzus persicae (Sulzer) comprised 31% of the aphid population in peanuts compared to 14% in soybeans and 17% in cowpeas and could be responsible for the higher number of peanut infections. In addition, trapping of live aphids in peanut fields showed …

Variability of the peanut mottle virus reaction in soybean (Glycine max)
… of the PMV strains by the green peach aphid (Myzus persicae Sulz.) was determined by counting infected test plants following natural feeding by aphids exposed to virus infected source plants. Transmission efficiency from pea (Pisum sativum L.) source plants to pea test plants was 11 to 36% and …

Mixed infections of maize dwarf mosaic virus and cucumber mosaic virus in maize
… were shown to be non-persistently transmitted by Myzus persicae, Rhopalosiphum padi and Rhopalosipbum maidis aphids. Protoplasts were isolated from maize seedlings and could be viably maintained for up to 66 hours. The maize protoplasts were infected with CMV and MDMV either singly, or together as …

Effect of predators on population dynamics of green peach aphid on flue-cured tobacco in Virginia
… 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 wackhimi, …

Interactions between Cucumber mosaic virus proteins and host proteins
… main insect vectors of CMV, the generalist aphid Myzus persicae. The 2b protein disrupts microRNA-mediated regulation of host gene expression by binding ARGONAUTE 1 (AGO1). In Arabidopsis, complete inhibition of AGO1 activity is counterproductive to CMV since this triggers antibiosis against …
