What is the purpose of bio-controls in pest management?

• A. Eliminate pesticides
• B. Replace other control practices
• C. Control non-native pests
• D. Reduce crop yields

Answer: (B)

Biological controls aim to suppress pest populations using natural enemies or living organisms, and they fit into an integrated pest management approach. The key purpose is to reduce reliance on chemical pesticides and provide sustainable pest suppression by letting predators, parasitoids, pathogens, or competitors help keep pests at acceptable levels. They’re most effective when used alongside other practices—cultural, mechanical, and, when needed, chemical controls—not as a complete replacement for all other methods. This balance helps minimize environmental impact and the risk of pest resistance while protecting crop yields.
