Pogrebnyk, S. (Institute of Zoology (Ukraine))
The mites in Ukrainian orchards were investgated. In total, 96 species from 32 families were found on apple trees; 24 species are added to the list of orchard mites. Most rich in species were families Phytoseiidae (18 species), Tydeidae (18 species), Stigmaeidae (7 species) and Cheylatidae (5 species). The constancy of Anthoseius caudiglans, Tydeus californicus, Amfitetranychus viennensis and Larryia reticulata increased, perphaps as a result of their tolerance to pesticides. During the last 30 years, the importance of the two bisexual species, Amphitetranychus viennensis and Panonychus ulmi, increased in apple orchards. Three groups of synthopic species were distinguished; (1) saprophages Oribatida and the family Pygmephoridae, (2) Mesostigmata (Phytoseiidae, Rhodacaridae, Aceosejidae, Laelaptidae, Veigaiaidae, Upropodidae) Bdellidae and Bryobiidae, and (3) a major part of the Prostigmata
