Description

VIII Expedição Científica do Departamento de Biologia – Ilha do Faial - 1993. During a survey in June-July 1993 in the Faial, Pico and San Miguel islands belonging to the Azores archipelago, 22 mite species were collected from different cultivated plants, shrubs and weeds. The most important group on the plants were phytoseiid mites with 13 species; tenuipalpid and tetranychid mites were the commonest among the phytophagous species. Amblyseius herbicolus (Chant) was the dominant mite species in the three islands and on both cultivated and spontaneous vegetation. Observations were made on geographical distribution, host plant relationships and mite presence on introduced and native plant species.
