In an IPM plan, what is the purpose of monitoring and identification?

• A. To calibrate equipment only.
• B. To determine presence and levels of pests to inform action thresholds.
• C. To measure fruit yield.
• D. To decide brand of pesticides to buy.

Answer: (B)

Monitoring and identification in IPM are about gathering real-time information on what pests are present, where they’re found, and how abundant they are. This data helps set action thresholds—predefined pest levels at which management actions should be taken to prevent economic or crop damage. Knowing the exact species is crucial because different pests respond to different control methods and timing; identifying the pest ensures you choose the right approach and avoid unnecessary treatments. When monitoring shows pests are below thresholds, you can skip or delay controls, supporting better pest suppression with fewer inputs and less disruption to beneficial organisms. While equipment and methods used for monitoring (like traps or scouting) are important, the core purpose is to inform whether and when to act, not just to calibrate gear, measure yield, or choose a pesticide brand.
