Resumo: | Mites started to be considered economically important on rubber tree since the early 1990's, when they were considered responsible for damages caused to this crop and by the consequent yield reduction. The aim of this work was to determine the mites present on this crop in the State of Mato Grosso and to elaborate a key for the separation of the species found. This study was conducted in fields of Plantacoes Edouard Michelin Ltda., in Itiquira, and Triângulo Agro-Industrial S/A. in Pontes e Lacerda. Samplings were conducted monthly in six different clones: PB 260, PR 255, IAN 713, IAN 873, FX 3864 and RRIM 600. Clones PB 260 and IAN 873 were sampled between August 1998 and July 2000; other clones were sampled between August 1999 and July 2000. In the season 1998/1999 samples consisted of 15 leaves of each of 10 plants taken randomly and in the season 1999/2000, 5 leaves of the median stratum of each of 15 plants taken randomly were sampled. A total of 4270 mites were found, belonging to 11 families. Nearly 77,2% of the mites collected belonged to the families Eriophyidae. Tarsone-midae. Tcnuipalpidae and Tetranychidae. composed predominantly by phytophagous species. Phytoseiidae was the most diverse family, with 15 species, followed by the families Tetranychidae and Eriophydae, with five species, and Tydeidae, with four species.
