Abstract: The two spotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae), is one of the most important pests on the cotton crop in Hatay region of Turkey. A two-year study was conducted between 2006 and 2007 to evaluate the population density of TSSM on cotton fields planted by dirt and asphalt roads. In 2006, the cotton plants nearby dirt roads had 1.72, 1.75, 4.04 and 2.65 times higher TSSM population than the cotton plants nearby asphalt roads in the four sampling dates, respectively. In 2007, the cotton plants nearby dirt roads had 5.54 and 10.64 times higher TSSM population than cotton plants nearby asphalt roads in two sampling dates, respectively. Consequently, the population densities of the TSSM were 1.79 and 13.86 times higher on the cotton plants nearby dirt roads than cotton plants nearby asphalt roads in 2006 and 2007, respectively. It is thought, the dusty conditions may bring about increasing population of TSSM on cotton plants.
