Which of the following is false about using biological pest control measures?

• A. Used Only When Pesticides Controls Have Failed
• B. Used To Kill Non-Native Pests
• C. Can Replace More Disruptive Or Hazardous Methods
• D. Requires Extensive Ecological Knowledge

Answer: (A)

Biological pest control works by using natural enemies, pathogens, or other living agents to suppress pest populations, and it’s a tool within integrated pest management rather than a last-resort option. It’s not reserved only for when chemical controls have failed; many programs plan and deploy biological controls proactively or alongside other methods to reduce pesticide use and slow resistance. This approach is commonly applied against non-native or invasive pests, helping to curb outbreaks with targeted action. It can also replace more disruptive or hazardous methods by providing long-term suppression with fewer environmental and health risks. Successfully using biological control typically requires understanding how pests and their natural enemies interact, recognizing potential non-target effects, and monitoring outcomes—though the amount of ecological detail needed can vary with the method. The statement that it is used only after pesticides have failed is therefore false.
