Cereal aphid

Cereal aphids are small, sap-sucking insects that primarily affect cereal crops like wheat, barley, and oats. They are typically green or black and can be found in colonies on the plants. By feeding on the plant's sap, they weaken the crops, leading to reduced yields. Additionally, cereal aphids can transmit diseases, further harming the plants. Farmers often monitor their crops for these pests and may use various methods, such as insecticides or natural predators, to control their populations and protect their harvests.
