What does "pesticide resistance" mean?

• A. The quick death of pests upon exposure
• B. The ability of pests to survive pesticide exposure
• C. The effectiveness of pesticides over time
• D. The increase in costs of pesticides

Answer: (B)

Pesticide resistance refers to the ability of pests to survive exposure to pesticides that were previously effective in controlling them. This phenomenon occurs when pests undergo genetic changes over time, allowing them to withstand toxic effects of the chemicals used against them. As a result, the efficacy of these pesticides diminishes, leading to the necessity of using higher doses or different pesticides, which often pose higher costs and environmental concerns. Understanding pesticide resistance is crucial in Integrated Pest Management (IPM), as it influences pest control strategies. Resistance can develop due to various factors, such as repeated applications of the same pesticide, leading to selection pressure on pest populations. By recognizing and addressing pesticide resistance, IPM practitioners can promote sustainable practices that minimize reliance on chemical controls, encouraging the use of alternative pest management strategies like crop rotation, biological controls, and habitat management.
