Which pest typically infests old grains?

• A. Confused flour beetle
• B. Larder beetle
• C. Carpet beetle
• D. Indian meal moth

Answer: (B)

The correct answer identifies the larder beetle as a pest that typically infests old grains. Larder beetles are known for their affinity for stored products, particularly in situations where food items have been improperly stored or left for extended periods. They are attracted to a variety of materials, including grains, meats, and other organic matter, which can often be found in older food supplies. In the context of pest management and fumigation practices, recognizing the behavior and preferred habitats of pests like larder beetles is essential for targeting infestations effectively. Once the larder beetle and their preferred food sources are identified, appropriate fumigation strategies can be implemented to eliminate them and prevent future infestations. The other options, while pests associated with different types of stored products, do not primarily target old grains in the same way. The confused flour beetle, for instance, is more commonly associated with flour and meal products. The carpet beetle typically feeds on natural fiber materials rather than grains, while the Indian meal moth is primarily known for infesting processed grain products such as cereals and flour, rather than old grains specifically. This clarity in the identification of pests is crucial for anyone involved in pest management, especially in the context of stored product protection.
