A.  aMites on grapevines in Northeast Brazilboccurrence, population dynamics and within-plant distribution.h[electronic resource]  c2014  aMite pests are some of the major limiting factors affecting grape production in the world. Despite the economic importance of the grapevines and the damage to them caused by some of the phytophagous mites in northeast Brazil, little is known about the mite fauna associated with this crop. The present study aimed to identify the mite fauna associated with grapevine, to evaluate the fluctuation of the populations of the most frequent species of phytophagous mites and their associated predators over a 12-month period as well as their within-plant distribution. Considering all varieties sampled, Tetranychus urticae Koch and Oligonychus mangiferus (Rahman & Sapra) comprised 74% of phytophagous mites. Euseius citrifolius Denmark & Muma and Neoseiulus idaeus Denmark & Muma comprised more than 80% of Phytoseiidae mites. The population dynamics study was conducted in a vineyard of Sugraone and a vineyard of Itália Muscat varieties. In these fields, E. citrifolius occurred at low population levels throughout the year, whereas N. idaeus was found only when high densities of T. urticae were observed. Tetranychidae and Phytoseiidae showed the same pattern of within-plant distribution, being found in higher densities on basal and median leaves and rarely they were found on apical leaves.  aBiological control  aGrapes  aMites  aOligonychus mangiferus  aPhytoseiidae  aControle biológico  aDoença  aInimigo Natural  aInseto  aTetranychus Urticae  aUva  aVitis Vinifera  aÁcaros fitófagos  aEuseius citrifolius  aNeoseiulus idaeus1 aMELO, J.
