For the first time in Europe, X. fastidiosa has been detected in the plant P. armeniaca. Samples came from an isolated apricot tree located close to plots with infected almond trees, in the municipality of Benissa. Also in this case, MLST analysis confirms that is the subspecies multiplex and the ST6.

Moreover, X. fastidiosa has been detected in 36 new specimens of Philaenus spumarius and 10 of Neophilaenus campestris, captured in the surroundings of infected almond tree plots.
