Some common stored product pests that attack stored grains and chew through the seed coat are ______.

• A. Indianmeal moth
• B. Flour beetles
• C. Webbing clothes moth
• D. Rice and granary weevils

Answer: (D)

Pests that damage stored grains by drilling into the kernel are true grain weevils. Rice weevil and granary weevil fit this pattern because they seek out whole stored cereal grains, bore into the seed coat with their snout, and feed from inside the kernel, often ruining the grain. The other pests listed are more associated with processed foods or textiles rather than intact grains—indoor pests that feed on flour, cereals, or fabrics rather than boring into whole seeds. So the ones that match the description—attack stored grains and chew through the seed coat—are rice weevils and granary weevils.
