Resumen: Grapevine trunks in Sherry vineyards (Andalusia, SW Spain), yielding important registered designation of origin wines, are seriously affected by the drywood termite Kalotermes flavicollis. In order to analyze the patterns and extent of occurrence of the infesting groups, a 16-month-long investigation was performed, during which termites collected from each colonized grape-vine trunk were recognized and counted according to the developmental stage or caste and the variation of caste proportions according to group size and season of occurrence was investigated. Results showed that different grapevine trunks exhibited different degrees of infestation, ranging from minuscule (0-50 individuals) to very large (more than 1000). Evaluating the composition and the occurrence of the colonizing groups, it was possible to determine that: a) minuscule groups, composed especially by eggs, reproductives, younger developmental stages and no alate adults, were probably 1-3 year old incipient colonies ...
