What type of damage do leafhoppers typically cause?

Leafhoppers are known for causing sucking damage to plants. This type of damage occurs when leafhoppers insert their mouthparts into the plant tissues and extract sap. The removal of sap can weaken the plant, leading to wilting, stunted growth, and yellowing of leaves. Additionally, as leafhoppers feed, they can introduce plant pathogens, such as viruses, which can lead to further complications and health issues for the plant.

The nature of the feeding behavior of leafhoppers distinguishes them from pests that cause chewing damage, which involves physical reduction of leaf and plant material. Root damage and pinching damage are associated with other pest activities, rather than the typical feeding mechanism of leafhoppers. Understanding the specific type of injury caused by a pest helps in formulating effective management strategies for preventing and mitigating their impact on crops and ornamental plants.
