Which of the following is a core pest that can be detrimental to stored products?

The term "core pest" refers to species that are particularly harmful to stored products, often leading to contamination and loss of goods. The firebrat is included in this category because it commonly infests stored products, especially in warm, humid environments. Firebrats feed on a variety of organic materials, including starchy substances and mold, which can pose a significant risk to the quality and safety of stored food items.

Other pests mentioned, while they can cause damage or issues in different contexts, do not primarily target stored products in the same way that firebrats do. Ants, for example, might invade homes or establishments seeking food but are generally not directly harmful to the integrity of stored products. Termites focus on wood and cellulose materials rather than food items. Cockroaches, although they can infest food supplies, are more often associated with unsanitary conditions rather than being a core pest that specifically targets stored products.

Understanding the specific behaviors and habits of pests is essential for effective management, especially in environments that store food or other goods. The firebrat's preference for warm, moist areas where it can thrive among stored products highlights its status as a significant concern for those managing inventory.
