(+)-Disparlure, the key sex pheromone component isolated from the female gypsy moth (Lymantria dispar), serves as a highly effective and species-specific female lure to attract males, primarily used for monitoring and controlling gypsy moth populations; in field applications, (+)-Disparlure used alone in lures can capture hundreds of male moths per trap per week, providing a more efficient and accurate reflection of male population dynamics in the field compared to traditional methods like light traps, making it a vital tool for monitoring and mating disruption within gypsy moth integrated pest management programs.
