“…In 2012, it was identified as a vector of the phloem-restricted pathogenic bacterium 'Candidatus Liberibacter solanacearum' (Lso) on carrots (Daucus carota L.) (Alfaro-Fernández et al, 2012b) and later identified as an Lso-vector on celery (Apium graveolens L.) (Teresani et al, 2014). Lso is an emerging vector-borne pathogen first described in America as causing disease in Solanaceae transmitted by Bactericera cockerelli Sulc (Secor et al, 2009) but later associated to Apiaceae in Europe and Africa (Munyaneza et al, 2010a;Alfaro-Fernández et al, 2012a;Loiseau et al, 2014;2015;Tahzima et al, 2014;Teresani et al, 2014). In northern Europe, Lso is transmitted by the psyllid Trioza apicalis Foerster, whereas in the southern Mediterranean, Lso is transmitted by B. trigonica.…”
