What pest is known for infesting old grain?

• A. Larder beetle
• B. Cigarette beetle
• C. Rice weevil
• D. Granary weevil

Answer: (A)

The larder beetle is recognized for infesting cured meats, cheese, and grain products that are stored improperly. Although it does have some association with old or stored food products, it is not specifically known for infesting old grain in the same manner as other pests are. On the other hand, the rice weevil and the granary weevil are more directly tied to infesting whole grains. The rice weevil specifically attacks rice, wheat, corn, and other whole grains, while the granary weevil is particularly associated with stored grains and feeds. This makes them key pests in grain storage facilities, leading to significant damage in the grain industry. The cigarette beetle primarily targets dried plant materials, especially tobacco products, but can also infest grains. However, its main association is less with general grain and more with specific dried goods. Thus, in terms of a pest that is specifically known for infesting old grain, the granary weevil is the most accurate choice due to its specialized behavior and impact on stored grains.
