What is an example of biological control?

• A. Sanitation
• B. Traps
• C. Using predators or parasites
• D. Quarantine

Answer: (C)

Using predators or parasites is an example of biological control because it relies on living organisms to suppress pest populations. By introducing or encouraging natural enemies—such as lady beetles that eat aphids, or parasitic wasps that lay eggs in pest insects—the pest numbers are kept in check through predation or parasitism. This approach can be targeted, often sustainable, and reduces the need for chemical pesticides. In contrast, sanitation focuses on removing pest habitats or food sources, traps provide a physical means to capture pests, and quarantine is a regulatory measure aimed at preventing pests from entering or spreading. These methods do not involve leveraging living organisms to control pests.
