What role do insects like sharpshooters and leafhoppers play in plant pathology?

Insects such as sharpshooters and leafhoppers are significant in plant pathology primarily because they can transmit fastidious bacteria. These insects feed on plant sap and, during this process, they can acquire bacteria that are pathogenic to plants. When they move to new plants, they may inject these bacteria into the plant’s vascular system, potentially leading to serious diseases.

This transmission can cause various negative effects on the host plants, ranging from reduced growth and yield to death, depending on the pathogenicity of the bacteria involved. The ability of these insects to act as vectors for such diseases underscores their importance in the context of agricultural health and pest management. Understanding this role is critical for developing effective strategies to manage both the insect pests and the diseases they can spread.
