Potentiality of Specific Predators in Controlling Certain Aphid Species on a Balady Orange Tree.

This study was aimed to assess the role of predators against the balady orange aphid species Aphis gossypii (Glover), Aphis citricola (van der Goot), Myzus persicae (Sulzer), and Aphis craccivora Koch. over the seasons of 2022 and 2023 successive Balady orange. The aphid species found on balady orange plants were Aphis gossypii and Aphis citricola. In the first season, three abundance peaks of A. gossypii were recorded, opposed to two peaks in the second season. In 2022, peaks of abundance were recorded in the fourth week of April and May, and the third week of June, with 378, 443, and 395 individuals per 40 leaves, respectively. In 2023, peaks of abundance were observed during the second weeks of April and May represented by 429 and 260 individuals per 40 leaves, respectively.During the 2022 and 2023 seasons, A. gossypii accounted as the majority of the aphid species found, with percentages of 65.92 and 64.59%. Following closely behind were A. citricola at 19.52 and 25.42%, A. c
