AB  - Spatial and vertical distributions, and population !uctuations of <i>Tetranychus urticae</i> and its predator <i>Phytoseiulus persimilis</i> were determined in four varieties of rose (Royal, Samuray, Red Baiser and Keiro) under greenhouse conditions. Nine samples for the pest and 8 samples for the predator were obtained. From 20 September to 18 November 2013, <i>T. urticae</i> and <i>P. persimilis</i> presented an aggregated distribution pattern during most of the sampling dates. At the same time, <i>P. persimilis</i> did not change the vertical distribution of <i>T. urticae</i>. A synchronous behavior between both predator and prey was observed in the four study varieties, although only the cultivars Royal and Samuray presented a signi"cant correlation (r= -0.708, P<0.05; r= 0.702, P<0.05, respectively).
