  DETECTION IN GALICIA OF SCAPHOIDEUS TITANUS Ball INSECT VECTOR OF GOLDEN FLAVESCENCE



Golden flavescence is an aggressive grapevine disease caused by a phytoplasm. First symptoms observed in the host are yield reduction, and later if the disease spreads in the vineyards, plants finally die.


Phytoplasm is a quarantine pathogen in the European Union, and occurs in some countries, with some affected areas in Southern France and Northern Italy. In Spain this disease was first reported in the Catalonian region of l'Alt Empordà. The natural vector of the disease is Scaphoideus titanus Ball, homopterous of the family Cicadellidae that does not cause important direct damages in grapevines but as vector of the disease it has an important economic significance. In Galicia programs of detection of the insect were initiated in 1999, and until 2007 the insect was not detected. However, in September 2007 two specimens were found in a trap placed in Crecente municipality (Pontevedra). Therefore, a more exhaustive survey needs to be performed in our region, although specific symptoms of flavescence were not observed so far.
