In 1995-1996, a survey was carried out in eleven viticultural regions of Greece in order to ascertain the species of predatory mites associated with vines. Twenty species of predatory mites (Phytoseiidae) were recorded: Phytoseius finitimus, Neoseiulus californicus, Euseius finlandicus, Typhlodromus hellenicus, Typhlodromus kerkirae, Typhlodromus exhilaratus, Kampimodromus aberrans, Euseius stipulatus, Amblyseius andersoni, Typhlodromus athiasae, Typhlodromus perbibus, Typhlodromus cotoneastri, Neoseiulus marginatus, Neoseiulus barkeri, Typhlodromus involutus, Typhlodromus intercalaris, Typhlodromus commenticius, Paraseiulus talbii, Typhlodromus recki and Phytoseius horridus. P. finitimus is the most dominant species since its population density reached levels of 75-100%, in most regions and varieties. It was followed by five other frequent species: N. californicus, T. exhilaratus, T. hellenicus, T. kerkirae and E. finlandicus. The remaining species were seldom collected. There are no marked differences between regions in the development of populations of P. finitimus. The highest densities occurred at the end of May to mid-June and between mid-August and mid-September. Only populations in the region of Volos peak at the end of November. Apart from a few isolated cases, the phytophagous species Tetranychus urticae, Panonychus ulmi, Brevipalpus lewisi, Colomerus vitis, Calepitrimerus vitis and Tenuipalpus granati did not cause extensive damage in vineyards.
