What are piercing and sucking pests?

Piercing and sucking pests are a category of insects that feed on plant sap by piercing plant tissues with specialized mouthparts called stylets. Common examples include aphids, leafhoppers, and whiteflies. These pests can cause significant damage to plants by depriving them of nutrients and potentially transmitting plant diseases. Their feeding behavior can lead to symptoms like wilting, yellowing, and stunted growth in affected plants.
