What is biological control? Give one example.

• A. Using some aspect of the pest's biology to control it, such as releasing natural enemies.
• B. Spraying broad-spectrum insecticides.
• C. Mechanical removal only.
• D. Genetic modification of the turf.

Answer: (A)

Biological control means using living organisms to reduce pest populations by tapping into natural relationships. This approach relies on predators, parasites, or diseases of the pest to keep it in check, often reducing or replacing chemical insecticides. It can involve releasing natural enemies into the environment, supporting their survival, or enhancing conditions so they thrive. For example, releasing beneficial insects like lady beetles to feed on aphids that infest turfgrass shows biological control in action, using the pest’s own natural enemies to lessen the pest problem.
