Abstract
The present study was conductedto evaluate the Seasonal abundance of Aphis gossypii Glover and assessment the percentage of infestation on okra plant at EI-Arish, , North Sinai Govemorate . A survey of the natural enemies of aphis was conducted and the percentages of parasitism were evaluated for two successive seasons 2005 & 2006. In season 2005 data indicated that the percentage of infestation caused by Aphis gossypii ranged from 10.11 to 59. 21% with an average of 31.34% and the percentages of parasitism ranged from 1 to 2% with an average of 0.25%. In season 2006 data indicated that the percentage of infestation ranged from 11.59 to 76.25% with an average of 34.18% and the percentages of parasitism varied from 1 to16% with an average2.25% .
