As a result of general survey of mites on apples in Lebanon, three genera including four species of the family Phytoseiidae were found during 1983-1984. The most important species, which were found in all apple growing regions and relatively in high densities, were Typhlodromus (Neoseiulus) invectus (Chant, 1959) and Typhlodromus pyri Scheuten, 1857. While the species Amblyseius finlandicus (Ondemans, 1915) and Phytoseius ocellatus Bayan, 1985 were found in some districts and their population densities were low; as compared with the first two other species. The adult stages of these four species were described and illustrated and some data on the species Typhlodromus (Neoseiulus) Kettanehi (Dosse, 1967), which has been found on apples in Lebanon by Gudo Dose, are given. A taxonomic key for determination of the above-mentioned species is also presented
