Oregon Pesticide Practice Test

Which pest management strategy focuses on the use of natural predators?

1. Mechanical

2. Cultural

3. Biological

4. Regulatory

The correct answer is: Biological

The focus of the correct answer is on utilizing natural predators to control pest populations, which is the essence of biological pest management. This strategy relies on the principles of ecology, where the natural enemies of pests, such as certain insects, birds, or microorganisms, are used to keep pest numbers in check. By harnessing these natural relationships, biological management not only helps in reducing the dependency on synthetic chemical pesticides but also promotes a balanced ecosystem. The goal is to enhance or introduce biological agents that can effectively manage pest populations without causing harm to non-target organisms. Other strategies, such as mechanical, cultural, and regulatory, do not emphasize the role of natural predators in pest management. Mechanical methods may involve physical removal or barriers to pests, cultural practices encompass changes in agricultural practices to make the environment less conducive to pests, while regulatory measures involve laws and policies to control pesticide use and ensure safety in pesticide application.
