Xylella fastidiosa is a vector-transmitted bacterial plant pathogen associated with serious diseases in a wide range of plants. It is therefore urgent to find measures to directly control, not only the vector but also the bacterium.

A key strategy in reducing Xylella fastidiosa infection in olive trees is to limit transmission of the pathogen by the xylem-sap feeding Philaenus spumarius (‘meadow spittlebug’). This polyphagous insect is the main Xf-vector in Italy and on almond in Mallorca and is widespread throughout Europe.

The control of the vector populations is a central pillar in the overarching strategies of controlling vector-borne diseases. Indeed, this has more relevance in the case of infections caused by Xylella fastidiosa (Xf), for which the lack of any effective therapy to cure infected hosts makes the control of the vectors crucial for the containment of the infections.


The deliverable describes in detail large-scale field trials performed in the season 2022 in Italy and Spain.

To understand the mode of action, the effects of novel biopesticide application on the plant’s defense system are analyzed via plant transcriptome analysis after biopesticide treatment.
