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 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...

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...

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...

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...

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...

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...

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...
