In the early 1990’s the glassy-winged sharpshooter, Homalodisca coagulata (Say), was found for the first time in California. The glassy-winged sharpshooter is a vector of the endemic bacterium, Xylella fastidiosa, which causes Pierce’s disease of grape. After the arrival of the glassy-winged sharpshooter, the spread of Pierce’s disease has been rapid in some regions; however, little is known about which factors have been most important to the spread of disease. A mathematical model was created to represent the complex ecological relationships involved in Pierce’s disease epidemiology. In the model, key data needed to understand epidemiology were identified. Identifying these data is an important step for prioritizing research that will lead to a more complete understanding of epidemiology and refining current management strategies.
