Age determination of the glassy-winged sharpshooter, Homalodisca vitripennis, using wing pigmentation
A red pigment is contained in the wing veins of the glassy-winged sharpshooter, Homalodisca vitripennis (Hemiptera: Cicadellidae). This insect is the main vector of the plant-pathogenic bacterium X...
A Survey of Sharpshooters (Hemiptera: Cicadellidae) in Virginia Vineyards, a Region of Expanding Concern for Pierce's Disease
A survey was conducted during the 2006 and 2007 growing seasons to record the presence of sharpshooters (Hemiptera: Cicadellidae) vectors of Pierce's disease in Vitis vinifera L. growing regions of...
Diversity and abundance of leafhoppers in Canadian vineyards
Leafhoppers (Hemiptera: Cicadellidae) are pests of many temperate crops, including grapevines (Vitis species). Uncontrolled populations can induce direct and indirect damage to crops due to feeding...
Draft Genome Resources of Two Strains of Xylella fastidiosa XYL1732/17 and XYL2055/17 Isolated from Mallorca Vineyards
Xylella fastidiosa is a plant-pathogenic bacterium that causes serious diseases in many crops of economic importance and is a quarantine organism in the European Union. This study reports a de novo...
Insect Vectors and Current Management Strategies for Diseases Caused by Xylella fastidiosa in the Southern United States
Xylella fastidiosa is a bacterial plant pathogen that causes Pierce's disease of grape, citrus variegated chlorosis, phony peach disease, alfalfa dwarf, and leaf scorch of plum, blueberry, and peca...
PCR Screening for Xylella fastidiosa in Grape Genebank Accessions Collected in the Southeastern United States
The National Clonal Germplasm Repository (NCGR) in Davis, California (CA) maintains the United States collection of warm-climate grapes in a field genebank in Winters, CA. This collection includes ...
RAPD fingerprinting Xylella fastidiosa Pierce's disease strains isolated from a vineyard in north Florida
Pierce's disease (PD) strains of Xylella fastidiosa were identified by random amplified polymorphic DNA (RAPD) fingerprinting. Two random primers including OPA-03 (agtcagccac) and OPA-11 (caatcgccg...
Testing the Efficacy of Barrier Plantings for Limiting Sharpshooter Spread
Barrier plantings have been used successfully in the management of plant diseases. Their effectiveness at limiting the incursion of the blue-green sharpshooter (Graphocephala atropunctata), an impo...
Understanding the effects of multiple sources of seasonality on the risk of pathogen spread to vineyards: vector pressure, natural infectivity, and host recovery
Seasonality plays an important role in the dynamics of infectious disease. For vector-borne pathogens, the effects of seasonality may be manifested in the variability in vector abundance, vector in...
Vitis sp. response to Xylella fastidiosa strain CoDiRO
Following a request from the European Commission, the EFSA Panel on Plant Health assessed a scientific report submitted by the Italian Authorities to the European Commission to support a request to...
Xylem structure of four grape varieties and 12 alternative hosts to the xylem-limited bacterium Xylella fastidious
The bacterium Xylella fastidiosa (Xf), responsible for Pierce's disease (PD) of grapevine, colonizes the xylem conduits of vines, ultimately killing the plant. However, Vitis vinifera grapevine var...
