Collection of data and information in Balearic Islands on biology of vectors and potential vectors of Xylella fastidiosa (GP/EFSA/ALPHA/017/01)

The pathogenic bacteria Xylella fastidiosa (Proteobacteria: Xanthomonadaceae) was detected in the Balearic Islands October 2016. In November 2017 EFSA granted data collection on biology of vectors Islands. grant included following objectives: i) Data by macrocosm and microcosm observations major agroecosystems; ii) Proposal field sampling protocols vectors; iii) Identification X. For study macrocosm, samplings were conducted Majorca, Ibiza, Formentera Minorca. study, cages containing one male female P. spumarius plant per cage placed at semi-field conditions. development guidelines, literature research conducted. vector competence experiments, collected insects caged with free plants Medicago sativa. From results, two Aphrophoridae (Hemiptera; Cicadomorpha) species have been Islands, Philaenus Neophilaenus campestris. Nymphs more abundant from early March to end May cover vegetation olive crops, followed vineyard almond ones. Adults June November, tree canopy August border October. trials showed that N. campestris able develop Lavandula dentata, Rosmarinus officinalis, Menta x piperita, Pistacia lentiscus Ocinum basilicum. average prevalence 2020 23 %. infected areas Majorca successfully transmitted uninfected M.
