Which of the following is not commonly categorized as a food or stored product pest?

The choice of paper as not commonly categorized as a food or stored product pest is accurate because paper pests typically feed on cellulosic materials rather than consumable food or stored products. While pests that affect grain, fabric, and rodents may directly impact food stores or agricultural products, pests associated with paper are more concerned with damaging items such as books, documents, and packaging materials.

Understanding the classifications of pests can help in pest management strategies. For instance, pests of grain are concerned with food supplies, fabric pests target textiles that may be contaminated or infested in a storage setting, and rodents are known to invade food storage areas, posing a risk by consuming food and contaminating it with droppings. As a result, recognizing that paper does not fit into the typical food or stored product category is crucial for effective pest control measures.
