What scouting method is used to monitor fall armyworms?

• A. Disclosing soap solution
• B. Visual inspection alone
• C. Pheromone traps only
• D. Soil core sampling

Answer: (C)

Monitoring fall armyworms hinges on tracking the adult moths with pheromone traps. These traps release specific pheromones that attract male moths, allowing you to gauge when moths are active and in what numbers. That early warning is crucial because the pest’s damage starts when eggs are laid and larvae hatch later. By knowing flight activity and peak emergence through pheromone traps, you can time field scouting and any needed controls more effectively, often before heavy feeding occurs. Visual inspection alone only shows existing damage or visible larvae, which can miss the initial flight activity and lead to delayed action. Soil core sampling isn’t relevant to this pest because fall armyworms feed above ground on foliage, not in the soil. Disclosing soap solution isn’t a targeted method for monitoring this moth species. Pheromone traps provide the best early indicator of FAW presence and informs when to start systematic scouting in the turf.
