Sherry vineyards, located in Andalusia (SW Spain) yield important registered designation of origin wines. These vines are affected by important sanitary problems caused by the termite Kalotermes flavicollis (Isoptera: Kalotermitidae) and the fungus Eutypa lata. A detailed investigation was performed during 15 months in nine districts of the Sherry area on differently aged vines of the “Palomino fino” variety. Samples were collected twice a month, cutting randomly selected vines into six sections, which were examined to detect the living status and the presence of arthropods (K. flavicollis, Reticulitermes lucifugus, ants) and fungi (Eutypa dieback disease, wood fungi). The results showed that among the 44% unhealthy vines, always aged more than 15 years old, K. flavicollis, found in almost 84% of cases, and often in contemporary presence with dead vine areas, represented the major pest of sherry vineyards, followed by Eutypa symptoms (14%), whereas Reticulitermes lucifugus, ants and wood fungi were found only sporadically. The characterization of the infestations, their trend over the seasons and their location in different sectors of the vines will be shown and discussed.
