Question: The main character of plant-parasitic nematodes (tylenchids) is the presence of….
Options:
Stomatostylet
Odontostylet
Both
None of these
✅Explanation:
The main characteristic of plant-parasitic nematodes in the order Tylenchida (tylenchids) is the presence of a stomato stylet. This is a specialized, needle-like mouthpart used to puncture plant cells and withdraw nutrients. The stomato stylet is a key adaptation that allows these nematodes to feed on plants and cause significant damage to crops.

🔑Key Points:
(b) Odontostylet: While similar in function, an odontostylet is a different type of stylet found in some predatory nematodes. It is typically larger and has tooth-like projections.
