Abstract

In 2013, an outbreak of Xylella fastidiosa was first identified in Apulia (southeastern Italy) in olive trees severely affected by a novel disease denoted Olive Quick Decline Syndrome (Complesso del Disseccamento Rapido dell'Olivo, CoDiRO in Italian). CoDiRO was first widely observed in 2010 and is characterized by extensive scorching and desiccation of leaves and twigs. At a preliminary examination, many of such trees appeared to be impacted by the presence of three different agents: (i) the leopard moth (Zeuzera pyrina), which drills galleries in the branches and trunks of olives; (ii) a set of xylem-inhabiting fungi of different genera (Phaeoacremonium and Phemoniella, in particular) (Nigro et al. 2014), which invade the sapwood taking also advantage of the moth galleries; and (iii) the bacterium X. fastidiosa. As time passed and a better insight into the disease was gained with field and laboratory observations, it became evident that the role of the leopard moth is minor, whereas the fungi could play the role of aggravators. Although the etiological role of X. fastidiosa is yet to be determined, the finding of this quarantine bacterium in the European Union prompted urgent investigations to address the many open questions and to enforce actions for its containment to avoid further spread in the neighboring areas and in other countries.
