Este trabalho teve como objetivos identificar a localização mais provável do ácaro-do-bronzeado (Dichopelmus notus Keifer) na planta de erva-mate e estudar a influência dos fatores climáticos em sua flutuação populacional. O estudo foi conduzido no município de Chapecó, SC, em um erval de dez anos, com árvores espaçadas no arranjo de 2,5 X 4,0m. Em três áreas de aproximadamente 2.500m², foram selecionadas 30 plantas, sendo avaliada a infestação quinzenal no período de 27/01/2004 a 10/01/2005. Foram observadas 18 folhas maduras de dez plantas escolhidas ao acaso em cada área, sendo seis no terço superior, seis no terço médio e seis no terço inferior, três em cada localização da copa, externa e interna. As inspeções foram executadas diretamente nos ervais utilizando lentes com aumento de dez vezes e 1cm² de campo fixo. Os resultados evidenciaram que os ácaros concentram-se na parte externa da copa da planta, nos terços superior e médio. As maiores infestações de D. notus ocorrem nos meses de fevereiro a abril, não tendo sido encontrada correlação linear significativa entre os elementos climáticos e o número médio de ácaro por cm² de folha. This study was was aimed at identifing the most likely location of the tan-mite (Dichopelmus notus Keifer) in mate-tea orchards and to study the influence of climate factors in its population fluctuation. The study was carried out in orchard of ten years, in the arrangement of 2.5 X 4.0m with height of 1.5 m, located in Chapecó, Santa Catarina state, Brazil. In three areas of approximately 2,500m², distant between itself about 100m, 30 plants had been selected randomly. Fortnightly, in the period of 27/01/2004 to 10/01/2005, were evaluated infestation of D. notus in 18 mature leaves of ten plants in each area, being six in the upper one-third, six in the medium one-third and six in lower one-third, three in each location of the crown, external and internal. The evaluations were executed directly in the orchard, using lenses with increase of ten times and 1cm² of fixed field. The results had evidenced that: the mites concentrate themselves in the external part of the plant in the upper one-third part of canopy as well as in the medium part one-third. The greatest infestation of D. notus occurred between February and April, not having been found significant correlation between the climate elements and the average number of mite for cm² of leaf
