Which pest is most likely to infest farm-stored grain?

• A. Cigarette beetle
• B. Rice weevil
• C. Confused flour beetle
• D. Granary weevil

Answer: (B)

The rice weevil is particularly well-known for infesting farm-stored grain. This pest is a small, winged beetle that has a knack for finding its way into grain storage facilities. They can infest a variety of grains including rice, corn, wheat, and other cereal products. Their ability to penetrate grain bags and bins makes them highly effective at establishing infestations in stored grain. One of the defining features of the rice weevil is its capacity to reproduce inside the grain kernels, where the larva develop, thus significantly impacting grain quality and yield. This makes them a major concern for farmers who store grains for long periods, as they can quickly cause considerable damage if not controlled. Understanding the behavior and biology of the rice weevil helps in managing grain storage effectively and mitigating the risks associated with stored product pests. Other pests like the cigarette beetle and confused flour beetle do pose threats to stored products, but they are less specifically associated with agricultural grains compared to the rice weevil, which is a primary pest in that context. The granary weevil is also significant, yet the rice weevil’s widespread impact and adaptability in grain storage situations make it the most likely to infest farm-stored grain.
