• Abstract: Analyses of spatiotemporal interactions between vector insects and pathogens are critical to understanding disease epidemiology. Sampling projects to assess Xylella fastidiosa (Xf) incidence in vineyards and sharpshooter trap catches from varying habitats were implemented in the Coachella Valley and lower San Joaquin Valley in California. Sampling was done at landscape and vineyard scales. Data from work in the Coachella Valley revealed low sharpshooter trap catches and two sharpshooter species had different spatial distributions at the landscape scale. Pierces disease is relatively rare throughout the Coachella Valley and did not occur near patches where sharpshooters were trapped. Analyses of similar data from the lower San Joaquin Valley are currently underway.
