Philaenus spumarius, is a widespread and polyphagous xylem-feeding insect. It is also the main vector of Xylella fastidiosa in Europe (Saponari et al., 2014). P. spumarius and P. tesselatus are considered sister species, differentiated at the male genitalia level but not at karyological, mitochondrial DNA and some nuclear genes levels (Maryanska-Nadachowska et al., 2012; Rodrigues et al., 2014). Genome-wide mar...
Xylella fastidiosa Wells et al. (Xf), as other phytopathogenic bacteria, is not directly controllable so disease management still largely relies on eliminating alternative hosts, suppressing xylem-feeding vector populations and using resistant cultivars. Its emergence in Europe with considerable negative impact on olive culture has emphasised the importance of extended monitoring of susceptible host plants and ...
