Describe the biological control method for pests.

• A. Utilizing synthetic chemicals to eliminate pests
• B. Employing natural predators or pathogens to manage pest populations
• C. Applying chemical fertilizers to promote plant growth
• D. Planting resistant crop varieties

Answer: (B)

The biological control method for pests involves employing natural predators or pathogens to manage pest populations. This approach leverages the existing ecological relationships where certain organisms can naturally suppress pest populations. For example, releasing ladybugs can help control aphid populations, as ladybugs are natural predators of aphids. Additionally, using beneficial microorganisms, such as specific fungi or bacteria, can target pest species without harming the plants or beneficial insects. This method is environmentally friendly, as it reduces reliance on synthetic pesticides, minimizes chemical residues, and can establish a more balanced ecosystem. While other methods, such as using synthetic chemicals to eliminate pests or applying chemical fertilizers to promote plant growth, are common pest management strategies, they do not fall under biological control. Planting resistant crop varieties is a preventative measure against pests rather than a direct biological control method. Hence, relying on natural agents aligns with the principles of integrated pest management and sustainability within agricultural practices.
