In stored grain, what damages can insects cause?

In stored grain, what damages can insects cause?

• A. Feeding damage reduces grain weight, nutrition value, and germination.
• B. Insect infestation can cause contamination, odor, mold, and more.
• C. Both feeding damage and contamination issues occur.
• D. No significant damage from insects occurs.

Answer: (C)

In stored grain, insects cause two main types of damage: direct feeding damage and indirect contamination that leads to spoilage. Direct feeding reduces the grain’s weight, nutritional value, and germination potential because pests chew and consume kernels. Indirect damage comes from contamination with insect fragments, frass, and odors, and it can promote mold growth, degrade appearance and quality, and even raise safety concerns from potential mycotoxins. Because insects do both harm the grain itself and create conditions that worsen spoilage, the best answer reflects that both feeding damage and contamination issues occur.
