| Abstract | ||
| Cucumber plants were cultivated in greenhouses in autumn and spring seasons, while autumn is the main season to provide markets with cucumber fruits in cold weather. The main pests of this season are Bemisia tabaci (Genn.), Aphis gossypii Glover and Tetranychus urticae (Koch) under plastic greenhouses were studied during two successive autumn season in (2008-2009) and (2009-2010) at El-Dokki location, Giza governorate. Cucumber plants in the early planting date were attacked by the highest population of B. tabaci while the highest populations of A. gossypii, and T. urticae were recorded in late planting date. This study also evaluated the potency of some control approaches to face the severe infestation of T.urticae on cucumber plants under greenhouse during summer season by using eight acaricides. The obtained results showed that the reduction percentages of T.urticae mobile individuals, 24 hours after treatments ranged between 96% by Agromec and 57.6% by Bio-fly, while after 7 days, all the tested acaricides were very effective against T. urticae. It was concluded that using any of the tested acaricides could be considered selectivity and safety. | ||
