Insect resistance is achieved by which action?

• A. Treating materials with chemicals
• B. Breeding crops to resist insects
• C. Using insects to pollinate crops
• D. Increasing the moisture of foods

Answer: (A)

Applying chemicals to materials creates insect resistance by adding substances that repel or kill insects that come into contact with or feed on the material. This protective chemistry acts as a barrier, reducing pest damage and preserving the product. Breeding crops to resist insects is a separate approach focused on the plant’s traits, pollinating insects relate to reproduction rather than resistance, and increasing moisture tends to encourage pests rather than deter them. So chemical treatment provides the immediate protective action that builds resistance against insect damage.
