RASPING AND SUCKING MOUTH PARTS
- Are found in thrips (Thysanoptera).
- The right mandible of thrips is reduced– and in some species completely absent.
- This beak contains the maxillae, hypopharynx, and the left mandible; together this structure forms a stylet.
- Thrips use the beak to rasp host tissues and take up liquid food through stylet.
