Abstract
Experiments were conducted during the three seasons of 2010/11and2011/12 and2012/13 at the Experimental Research Station in Moshtohor‚ Faculty of Agric ‚Benha Unv. ‚Qalubia Governorate, Egypt. Three phosphorus fertilization levels (0, 100, and 200kg/fed) were applied to clarify their effects on the population density of aphid spp and thrips (Thrips tabaci). in Faba bean fields, its relationship with chemical components on leave sand susceptibility of the two varieties (Giza843 and sakha2). The obtained results showed that the highest population densities of these pests occurred at no phosphorus fertilization(control) followed by 100 kg/fed , . The lowest population densities were recorded for the treatment at 200 kg/fed. On the other hand, sakha2 var .received the lowest infestation. Significant differences between the means of chemical components in leaves of Faba bean plants were obtained
