| Abstract |
These studies were carried out in El-Mansoura district, Dakahlia Govemorate during the two seasons of 200412005 and 2005/2006 on different citrus trees (Navel orange, Mandaiin and Valencia orange). The present study illustrated that Aphis gossypii Glover, Aphis citricola (V.D. Goot) had two peaks at April and August during the two seasons of investigation. While, Myzus persicae (Sulzer) and Aphis craccivora Koch had one peak occurred during March and April for the two seasons. Each aphid species showed different degrees of preference for the different tested citrus trees. A. gossypii exhibited higher population on Mandarin trees. While Navel orange receive the highest population of A. citricola and M. persicae. The weather factors play a great role on the population density and seasonal abundance of the tested aphid species.
