Which of the following is a common insect pest of stored grain products?

• A. Ladybug
• B. Granary Weevil
• C. Ant
• D. Termite

Answer: (B)

The Granary Weevil is known specifically for its role as a pest in stored grain products. This insect primarily infests and damages grains by boring into the kernels, which leads to significant losses in food quality and quantity. The life cycle of the Granary Weevil is closely associated with stored grains, as it lays its eggs inside the grains, and the larvae feed on the starches, resulting in visible damage and decreased grain viability. In contrast, ladybugs are generally beneficial insects, primarily preying on aphids and other pests rather than infesting grain. Ants can sometimes be found in stored goods but are not specifically associated with grain damage in the same manner as Granary Weevils. Termites are wood-destroying insects that typically cause damage to wooden structures and do not target stored grain products. Thus, Granary Weevils are distinctly recognized as the principal insect pest affecting stored grains, making them the correct choice in this context.
