Abstract

The fate of strains of the bacterium Xylella fastidiosa that cause Pierce's disease of grapevines was investigated in 33 species of mostly perennial plants common in riparian habitats in northern coastal California grape-growing regions. Plants were inoculated in the field with needle puncture using cultured cells of X. fastidiosa as inoculum or inoculated in the laboratory with infective insect vectors (Graphocephala atropunctata). Populations of X. fastidiosa were highest in most plant species within 3 to 6 weeks of inoculation, followed by declines in populations of viable bacteria over the next 3 to 4 months. Homogenates of petioles of California black walnut (Juglans hindsii) and coffeeberry (Rhamnus californica) inhibited in vitro growth of X. fas-tidiosa, precluding culture of the bacterium from these plants. Big leaf maple (Acer macrophyl-lum), California buckeye (Aesculus californica), California blackberry (Rubus ursinus), coast live oak (Quercus agrifolia), elderberry (Sambucus mexicana), French broom (Genista monspessulanus), periwinkle (Vinca major), valley oak (Quercus lobata), and the grape root-stock Vitis rupestris supported systemic populations of X. fastidiosa that survived throughout the year outdoors in Napa Valley, California.
