Abstract

Seven treatments; phytosiulus macropilis Banks, Amblyseius californicus, Parok, Akkomic, Shilinger, Agromactin and Ortus were used to control Tetranychus urticae Koch on two strawberry cultivars, Sweet-Charlie and Camarosa in Qalubia Governorate. On Sweet-Charlie cultivar the results showing that the reduction percentage of movement stages was the highest when use Agromactin (80.55%) and Ortus (78.29%) for eggs; on the contrary it was the lowest when use Shilinger (54.72%) and Akkomic (68.95%) for movement and eggs, respectively. On Camarosa cultivar the reduction percentage was the highest when use parok (77.40% & 78.18%) for movement stages and eggs, respectively, while it was the lowest when used Shilinger (68.22%) and Ortus (69.07%) for movement stages and eggs, respectively.
