Abstract : To identify and evaluate the occurrence of arthropod pests and predators on mangoes at Vale do São Francisco, northeastern Brazil, studies were carried out in eight commercial plantations of cv. Tommy Atkins, from February 2000 to January 2002. In each area, fruit flies were collected using McPhail and Jackson traps; other pests and predators were evaluated on samples of branches, panicles and fruits. The arthropod pests occurrence in decreasing order were: Aceria mangiferae (Acari: Eriophyidae) - 87.0%; Pseudaonidia trilobitiformis (Hemiptera: Diaspididae) - 70.1%; Ceratitis capitata (Diptera: Tephritidae) - 66.1%; Erosomyia mangiferae [Procontarinia mangiferae] (Diptera: Cecidomyiidae) - 64.6%; Pleuroprucha asthenaria (Lepidoptera: Geometridae) - 42.9%; Polyphagotarsonemus latus (Acari: Tarsonemidae) - 39.3%; Anastrepha spp. (Diptera: Tephritidae) - 33.0%; Selenothrips rubrocinctus (Thysanoptera: Thripidae) - 26.4%; Oligonychus sp. (Acari: Tetranychidae) - 16.6%; Frankliniella schultzei (Thysanoptera: Thripidae) - 13.1%; unidentified mirid - 9.1%, and aphids (Aphis craccivora; Toxoptera aurantii, A. gossypii (Hemiptera: Aphididae)) - 7.2%. The predators were: Euseius concordis and E. citrifolius (Acari: Phytoseiidae) - 32.7%; Cheletogenes ornatus (Acari: Cheyletidae) - 32.3%; Rubroscirus sp. [Cunaxa sp.] (Acari: Cunaxidae) - 17.7%; unidentified arachnids - 16.6%, and Chrysoperla externa and Ceraeochrysa cubana (Neuroptera: Chrysopidae) - 3.7%.
