What is the purpose of monitoring in an IPM program?

• A. To track weather patterns to predict outbreaks.
• B. To detect pest activity early, identify species, assess infestation levels, and guide decisions on whether and when to intervene.
• C. To spray pesticides on a fixed schedule.
• D. To record pesticide sales.

Answer: (B)

Monitoring in IPM is about gathering information on pest activity and site conditions so you can make informed decisions. It aims to detect pests early before damage occurs, identify the pest species to choose effective controls, assess how severe the infestation is, and decide if and when intervention is needed. This approach lets you apply controls only when necessary, target the right species, and minimize unnecessary pesticide use and impacts on non-target organisms. For example, finding only a few pests with no damage might lead to continued observation rather than spraying, while confirming a harmful species at high levels would prompt an intervention. Tracking weather patterns can influence pest risk, but it isn’t the primary purpose of monitoring for guiding action. Spraying on a fixed schedule ignores actual pest pressure and is not consistent with IPM. Recording pesticide sales doesn’t provide the direct pest information needed to decide on control measures.
