What is the primary crop affected by the cotton aphid, Aphis gossypii?

The primary crop affected by the cotton aphid, Aphis gossypii, is cotton. This insect is particularly known for infesting cotton plants, where it can cause significant damage by feeding on the plant's sap. The cotton aphid can lead to reduced yields and overall plant health through direct feeding and by transmitting plant viruses. Identifying cotton as the primary crop affected underscores the importance of monitoring and managing aphid populations in cotton production systems to mitigate potential economic losses.
