Question: Stomatostylets are found in..
Options:
Tylenchids
Dorylaimids
Both
None of these
✅Explanation:
Stomatostylets are needle-like feeding structures derived from the lining of the stoma (mouth) in nematodes. They are primarily found in the order Tylenchida, which includes many important plant-parasitic nematodes like root-knot nematodes, cyst nematodes, and lesion nematodes. These stylets are used to puncture plant cells and withdraw nutrients, causing significant damage to crops.

📌Other Options Explanations:
(b) Dorylaimids: Dorylaimids also have stylets, they are called odontostylets, and their origin is different. Odontostylets are derived from a single tooth-like structure and are typically larger and more robust than stomatostylets.
