How do sucking pests feed?

Explanation:
Sucking pests feed by piercing plant tissues with specialized mouthparts and drawing out sap. They use slender, needle-like stylets to reach vascular tissue, typically tapping into the phloem or xylem to suck up sap. This feeding mode is different from chewing pests, which physically bite and eat leaf tissue, and from plant processes like absorbing water through roots or photosynthesis. Sap-feeding can cause symptoms such as leaf curling, stippling, and honeydew, and can also enable transmission of plant viruses.
