    Evaluation population density of Tetranychus urticae Koch on cotton fields planted nearby dirt and asphalt roads
    (2008) Demirel, N.; Çabuk, F.
    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. © 2008 Academic Journals Inc.

    Population trends of two spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae) on cotton nearby soil and asphalt road
    (Asian Network for Scientific Information, 2008) Demirel, N.; Çabuk, F.
    The two spotted spider mite (TSSM), Tetranychus urticae Koch (Acari: Tetranychidae) is one of the most important pests on cotton crops in Amik plain of Turkey. The sampling were taken from forty-eight an irrigated cotton crop fields to describe affectability of dusty condition for the TSSM' population density. The population densities of two spotted spider mite were 1.72, 1.75, 4.39 and 2.65 times higher on cotton nearby soil road than asphalt road. Therefore, the dusty conditions can bring about increasing population of TSSM on cotton plants. Due to the dusty conditions, their beneficial insects were not affected on their population density. The decreasing of dusty condition can be reduced population density of TSSM and increase affectability of their beneficial insects. © 2008 Academic Journals Inc.
