Which option best describes the purpose of using biological control agents?

• A. Using natural enemies to suppress pests
• B. Using broad-spectrum pesticides
• C. Increasing pesticide dependence
• D. Developing resistant crops

Answer: (B)

Biological control uses natural enemies to suppress pest populations, relying on predators, parasitoids, and diseases to reduce pest numbers rather than chemical inputs. The goal is to keep pest levels at acceptable thresholds in a way that's targeted and environmentally friendlier, often as part of an integrated pest management plan. Because these agents typically affect specific pests or groups, they minimize harm to beneficial insects and other non-target organisms compared with broad-spectrum pesticides. This approach is different from using chemicals that kill wide ranges of organisms, and it isn’t about planting resistant crops or increasing reliance on pesticides.
