Pheromone traps are used to monitor adult populations and time control actions. Which step does this action primarily support?

• A. Egg scouting
• B. Adult population monitoring
• C. Larval development tracking
• D. Pest exclusion through barriers

Answer: (B)

Pheromone traps sample the number of adult insects by attracting them with species-specific pheromones, giving a read on how many adults are present and how their population is changing over time. This makes them a direct tool for monitoring the adult population and for timing control actions to when adults are active or at a threshold. They don’t measure eggs or larvae, so they aren’t used for egg scouting or larval development tracking, and they don’t function as physical barriers to exclude pests. In short, they support watching the adult population to guide when to apply control measures.
