Abstract
Many different species of leafhoppers were found attacking cotton plants causing serious damage to the plants. Therefore, this work was canted out to survey the species of leafhoppers and their time of appearance in cotton fields at Sakha Agric. Res. Station Farm, Kafr El-Sheikh during two successive seasons, 1999 and 2000. Monthly samples with sweeping net on cotton indicated the existence of nine species of leafhoppers belonging to Five genera from two subfamilies, Typhlocybinae and Deltocaphalinae of family Cicadellidae, Homoptera. Four species belonged to genus Empoasca, Empoasca dedpiens Paoli, Empoasca decedens Paoli, Empoasca lybica Paoli and Empoasca distinguenda (de Berg), two genus Ocadulina, Ckadulina typuncatella zeae China and Ckadulina chinai (Ghauri) and one species belonging to genus Exitianus, Exitianus caploota Sral. And one species belonging to genus Macrosteles, Macrosteles sexnotatus Fall in additional of Orosiussp. E. deaptens was the most abundant species followed by E. decedens and they appeared on cotton plants from May until October, while OMS/US sp. and C dilnai composed the lowest portion of the population and they appeared lately during the period from June to October. However, the gained results are of great importance in planning programs of integrated pest management in cotton fields.
