Plant injurious and predatory mites on Quercus spp. in Greece

The study deals with the plant injurious and predatory mites found on Quercus spp. in Greece. The examination of a large number of samples from Quercus spp. revealed the presence of 12 species of plant injurious mites belonging to the families: Eriophyidae (10 species) and Diptilomiopidae (2 species).Three species of the family Tarsonemidae were also found. The species of the family Eriophyidae belong to 8 genera: Cecidophyes (2 species), Aceria (2 species), Bariella (1 species), Achaetocoptes (1 species), Acaricalus (1 species), Acarelliptus (1 species), Caliphytoptus (1 species) and Glyptacus (1 species). The species of the family Diptilomiopidae belong to 2 genera: Diptacus (1 species) and Rhyncapytoptus (1 species). While the species of the family Tarsonemidae belong to the genera: Tarsonemus (2 species) and Dendroptus (1 species). Along with the above mentioned mites, 19 species of predatory ones were found belonging to 3 families: Phytoseiidae (14 species), Stigmaeidae (3 species) and Cunaxidae (2 species). The species of the family Phytoseiidae belong to 2 genera: Typhlodromus (12 species) and Amblyseius (2 species). The species of the family Stigmaeidae belong to 3 genera: Stigmaeus (1 species), Storchia (1 species) and Zetzelia (1 species). While the species of the family Cunaxidae belong to the genera: Cunaxa (1 species) and Cunaxoides (1 species). All eriophyoid mites found and two of the three species of the family Tarsonemidae are recorded for the first time in Greece. For each species data are provided about its distribution to various Quercus species as well as its global distribution.
