What does suppression in IPM refer to?

• A. Encouraging pest populations
• B. Reducing pest numbers to an acceptable level
• C. Eliminating all pests from the environment
• D. Increasing the use of synthetic chemicals

Answer: (B)

Suppression in Integrated Pest Management (IPM) is primarily focused on reducing pest populations to an acceptable level that minimizes damage to crops and the environment. Instead of aiming for complete eradication of pests, which is often not achievable and can lead to ecological imbalance, suppression aims to manage pest numbers effectively. This approach acknowledges that some pests will always be present but seeks to keep them below a threshold that causes harm.

The concept of suppression is rooted in sustainable practices; it allows for the natural balance of the ecosystem to be maintained while still protecting agricultural yields. This balance is crucial because it avoids the negative consequences of over-reliance on chemicals or aggressive pest control measures, which can lead to resistance or harm beneficial organisms. Therefore, in the context of IPM, suppression recognizes the importance of managing rather than completely eliminating pest populations.
