The sweet potato weevil primarily affects which part of the plant?

Leaves
Stems
Tubers
Roots

The correct answer is: Tubers

The sweet potato weevil primarily affects the tubers of the sweet potato plant. This pest infests the tubers, where it lays its eggs. The larvae that hatch from these eggs feed on the tuber tissue, leading to significant damage. As the sweet potato is a root vegetable primarily grown for its underground tubers, damage to this part can greatly impact yield and quality. Understanding the life cycle and feeding habits of the sweet potato weevil is crucial for effective pest management. Monitoring and controlling this pest is particularly important during the growing season, especially as it can lead to reduced harvests and economic loss for farmers.
