Tetranychus urticae Koch (Acari: Tetranychidae) is one of the most important pests in greenhouses. This harmful pest has rapidly developed high resistance to many classes of acaricides. In this study, T. urticae populations were collected from cucumber greenhouses in Gümenek village, Tokat, Turkey. Growers in this location use acaricides such as abamectin, hexythiazox and spiromesifen to suppress T. urticae populations. The study aimed to determine the resistance levels of T. urticae populations against to mentioned acaricides. The LC50 values of the collected populations were determined by the spray tower-leaf disc method. The resistance rates were found by dividing the LC50 values of the collected greenhouse populations by the LC50 value of the susceptible population. The resistance levels of T. urticae were determined to be between 1.88-2.14-folds against abamectin, 1.67-1.84 folds against hexythiazox and 1.77-2.09 folds against spiromesifen. According to these results, a low rate of resistance development was observed against abamectin, hexythiazox and spiromesifen.
