Abstract
A study was carried out of the mite fauna of peach trees in Portugal, based on samples taken all over the country, especially in areas where these fruit trees are of economic importance. Mites were found in 45% of the 400 samples taken. The eriophyid Aculus fockeui (41.6%) and the tetranychid Tetranychus cinnabarinus (20.0%) were the most frequent phytophagous mites. The former causes leaf silvering and the latter produces bronzing symptoms on foliage. However, predaceous mites comprised the largest number of species, the phytoseiid Amblyseius stipulatus [Euseius stipulatus] (11.2%) being the commonest and most important. Indifferent mites, usually feeding on fungi, were chiefly represented by the tydeid Orthotydeus californicus (30.4%)
