Özet: The aim of this study was to determine the mite species and the population densities of pest and important predatory mites in the vineyards of Çanakkale Province. Totally, 7 mite species belonging to 5 families, Tetranychidae, Eriophyidae, Phytoseiidae, Stigmaeidae and Tydeidae, were identified on the vineyards. Phytoseius finitimus Ribaga (Acari: Phytoseiidae) was the most abundant predator among all Phytoseiid species with a rate of 49.3 %, whereas Tetranychus urticae Koch (27%) and Colomerus vitis Pagenstecher (6.6%) (Acari:Tetranychidae; Eriophyidae) are the most common pest mite species in the vineyards of the region. The second part of study was conducted in four vineyards in the Çanakkale Province, during the growing seasons of 2008-2009. Surveys were carried out in every week from May to September on Çavuş and Karasakız varieties and 20 leaves were collected from each variety and vineyard. The results of study indicated that the population densities of Colomerus vitis began to increase generally in early June and reached the maximum level with 9.35 and 4.35 gall/leaf in late June, 2008 and 2009, respectively. The population fluctuation continued until the end of September. The most effective predatory species P. finitimus and neutral species Tydeus californicus (Acari: Tydeidae) were dominant mites in the vineyards and it was observed that their population reached to 6.9 and 7.85 mites/leaf, respectively. Also, it was determined that the predatory mites showed very low population development in the sprayed vineyards
