Which of the following is a key principle of Integrated Pest Management (IPM)?

The key principle of Integrated Pest Management (IPM) is to incorporate various pest management strategies. This approach is designed to provide a comprehensive, effective, and environmentally sensitive response to pest problems. By combining multiple strategies such as biological control, habitat manipulation, cultural practices, and the judicious use of chemical pesticides when necessary, IPM aims to manage pest populations while minimizing risks to human health and the environment.

IPM emphasizes the importance of monitoring pest levels and understanding the life cycles of the pests, which informs decision-making. This multifaceted method allows for flexibility and adaptability, addressing the specific pest situations in different environments rather than relying solely on one method or material.

In contrast, strict reliance on chemical pesticides would not promote a sustainable, long-term solution and could lead to resistance among pest populations. Using a single method for all pests neglects the diversity of pests and their behaviors, resulting in ineffective control measures. Ignoring pest thresholds can lead to unnecessary pesticide applications, which does not align with the IPM's goal of applying control measures only when pest populations reach a level that necessitates action.
