Description

Three 16SrIII-J phytoplasma-positive vineyards were visited each 15 days from September 2017 to August 2018  to capture
insects using entomological sweep nets and yellow sticky traps. Additionally weeds showing typical symptoms associated
with the presence of phytoplasmas were also collected. The phytoplasma 16SrIII-J was detected for the first time in the
leafhoppers Amplicephalus ornatus, A. pallidus  and Bergallia  sp., and in the weed Brassica campestris.  Another phytoplasma
classified as 16SrXI, was detected in one leafhopper belonging to the genus Paratanus.  The identification of the 16SrXI ribosomal
subgroup and the species of Bergallia  sp.  and Paratanus  sp.  are in progress, as well as the transmission trials with these two
insects plus A. pallidus  and A. ornatus.
