Abstract
En 中文
Olive quick decline syndrome (OQDS), caused by Xylella fastidiosa subsp. pauca ST53, has devastated olive groves in Apulia (southern Italy), severely impacting olive production and rural agroecosystems. High populations of the key insect vector Philaenus spumarius (Hemiptera: Aphrophoridae) and agricultural landscapes dominated by susceptible olive cultivars have driven epidemic spread. Replanting with resistant olive cultivars is currently supported as a key restoration strategy for olive growers and olive oil industry. This study evaluated the transmission efficiency of X. fastidiosa ST53 by P. spumarius from and to resistant olive cultivars Leccino and FS17 compared with susceptible ones, using field and controlled experiments conducted over 3 years.
