Cotton aphid, Aphis gossypii Glover (Homoptera: Aphididae), is one of the most injurious insect pests which suck the cell sap and considered one of the cotton yield limiting factors (Fondren et al., 2004).Aphids damage is due not only to its direct feeding, but also to honeydew production during boll set resulting in sticky cotton that can decrease cotton lint quality (Carter, 1992). <, Egyptian Journal of Biological Pest Control, Egypt J Biol Pest Control, doi:10.1186/s41938-018-0065-9, On the control of the cotton aphid, Aphis gossypii Glov.

Among the cotton pests, the cotton aphid Aphis gossypii Glover is an important pest that infests at the beginning of the crop season, delaying early plant development; the aphid infestation might extend through the development of the plants if control practices are not adopted.
