Which insect pest primarily damages stored grains as an adult?

• A. Drug store beetle
• B. Indian meal moth
• C. Rice weevil
• D. Cigarette beetle

Answer: (C)

The rice weevil is well-known for being a significant pest of stored grains, particularly as an adult. Adult rice weevils are capable of boring into whole grains and laying eggs inside them, which can lead to extensive damage to grain supplies. They primarily target grains such as rice, corn, and wheat, as these grains serve as a food source for both the adult weevils and their larvae. Understanding the behavior of the rice weevil is crucial in pest control efforts, as their life cycle involves infesting grains and reproducing within them, making it difficult to eradicate once they establish themselves. This infestation can lead to substantial losses in food quality and quantity, making it essential to monitor and control rice weevil populations in storage facilities. While other insects mentioned also have impacts on stored products, such as the drug store beetle and the cigarette beetle, they do not specifically have the rice weevil's ability to infest whole grains as adults. The Indian meal moth primarily damages stored grains in its larval stage rather than as an adult.
