What role do monitoring tools (traps and pheromone lures) play in IPM?

• A. They detect and quantify pest activity, identify species, and guide treatment timing and method.
• B. They permanently eradicate pests.
• C. They increase pest reproduction.
• D. They have no practical use.

Answer: (A)

Monitoring tools in IPM provide early detection of pest presence, quantify activity, and identify species, which in turn guides when and how to treat. Traps give a read on pest numbers and movement, while pheromone lures reveal which species are present and help track the timing of their life cycles. This information helps set action thresholds, choose the most effective control method, and time interventions for maximum impact while avoiding unnecessary treatments. For example, pheromone traps that attract specific pests allow you to detect an outbreak early and plan targeted tactics, such as mating disruption or precisely timed applications. These tools are about gathering information and guiding actions, not permanently eradicating pests by themselves.
