EXPLANATION
Nematode Parasites of Vegetables, Fruits, Plantation, Spices, Floricultural & Storage Crops
- Post-Harvest Damage by the Yam Nematode (Scutellonema bradys):
- Biology: Scutellonema bradys (the yam nematode) is a migratory endoparasite that attacks tubers of Dioscorea spp.
- Storage Reproduction: Unlike most plant parasitic nematodes that enter dormancy after harvest, Scutellonema bradys continues feeding and multiplying rapidly inside yam tubers during post-harvest storage, causing extensive vascular dry rot, deep cracking, and complete desiccation of tuber tissues.
- Conclusion: Scutellonema bradys feeds on underground plant parts during storage (Option 4).
Correct option: (4) Scutellonema bradys
