Abstract
The present experiments were conducted in a private cucumber field in Ibshwai, Fayoum governorate during the two successive years (2018 and 2019) to evaluate the influence of sowing dates on the aphid species that attacking cucumber crop in Fayoum governorate. The cotton aphid Aphis gossypii reached the highest peak of abundance in March sowing date in the fourth week of April  2018  (916 individuals/sample) and in the first week of May 2019 (1083 individuals/sample). While, in August sowing date, A. gossypii reached the highest peak of abundance in the fourth week of October 2018 and 2019 with 671 and 783 individuals/sample, respectively. Moreover, in October sowing date, A. gossypii reached the highest peak of abundance in the second week of November 2018 and in the third week of November 2019 and represented by 934 and 1214 individuals/sample, during the two years, respectively. The green peach aphid, Myzus persicae recorded the highest peak of abundance in March sowing date in the second week of April 2018 (317 individuals/sample) and in the fourth week of April 2019 (324 individuals/sample). While in August sowing date M. persicae recorded the highest peak of abundance in the second week of October 2018 and in the fourth week of September 2019 and presented by 428 and 302 individuals/sample, respectively. Meanwhile, in October sowing date, M. persicae recorded the highest peak of abundance in the second week of November 2018 and 2019 and presented by 183 and 124 individuals/sample, respectively.
