Field experiments were undertaken during 2009 and 2010 seasons at Toukh Tanbisha village, Berkat El-Sabaa region, Minufiya Governorate, Egypt. The obtained results indicated that cotton seeds treated with imidacloprid increased emergence of cotton seedings, improved germination and increased stem length. The systemic insecticide (imidacloprid) was found to be most effective recording the least populations of aphids, leafhopper, thrips, green bug, whitefly and mite, protected cotton plants from sucking insects. Understanding the relationship between fertilization and the incidence of insect pests is essential for the management of chemical fertilization and insect pests in recent agroecosystem. Effects of combination of phosphorus, nitrogen and potassium fertilizers on the population dynamics and density ofcotton pests Aphis gossypii,Thrips tabaci and Empoasca spp. were studied. Results indicated that numbers of adult or immature stages of Tetranychus urticae significantly varied among nitrogen treatments .This study indicated that increasing nitrogen level in the range of 60 to 90 kg /faddan, enhanced mite population on cotton leaves.
