Biological control uses natural enemies to suppress pest populations.

• A. True
• B. False
• C. Not sure
• D. Sometimes

Answer: (A)

Biological control relies on using living natural enemies—predators, parasitoids, and pathogens—to reduce pest populations. By leveraging these relationships, pests are kept in check without relying solely on chemical pesticides. It can involve releasing natural enemies that attack the pest, protecting or enhancing those enemies already present, or a combination of both. For example, releasing lady beetles to eat aphids, deploying parasitic wasps to target pest eggs or larvae, or using microbial agents that infect specific pests. When conditions are favorable, these natural enemies can suppress pest numbers and sometimes provide ongoing control. The core idea is that pests are kept in check by their natural foes, so the statement is true.
