Resumo: | Phytoseiidae and Sigmaeidae are the most common predatory mites on rubber tree leaves in the State of Mato Grosso, associated with phytophagous mites of the families Eriophyidae, Tenuipalpidae and Tetranychidae. The aim of this work was to compare the effect of different kinds of food, including different species of mites commonly found on the rubber tree in Mato Grosso, and one kind of pollen, on the oviposition of the predators Agistemus floridanus Gonzalez, 1965 (Stigmaeidae), Euseius concordis (Chant, 1959) and Neoseiulus anonymus (Chant &amp;amp; Baker, 1965), both Phytoseiidae. Those predators are common on rubber tree leaves in Mato Grosso. For the tests with A. floridanus, discs of 2 cm in diameter of rubber tree leaves were used as substrate. Food provided to the predators were the mites Calacarus heveae Feres, 1992, Oligonychus gossypii (Zacher, 1921), Polyphagotarsonemus latus (Banks, 1904), Tenuipalpus heveae Baker, 1945 and Tetranychus mexicanus (McGregor, 1950), and pollen of Typha angustifolia L. Agistemus floridanus accepted a larger variety of foodthan other predators. This was the only predator with high oviposition rate when fed C. heveae and T. heveae, the phytophagous mites considered most important on rubber trees. Euseius concordis and A. floridanus had nearly the same oviposition rates when fed pollen of T. angustifolia (ca. one egg per female per day). Neoseiulus anonymus had the highest oviposition rate than other predators when fed O. gossypii and T. mexicanus. Polyphagotarsonemus latus was the least suitable food for the predators studied.
