Male moths find potential mates by following the trail of a scent (pheromone) emitted by the female of the same species. Mating disruption is used to prevent mating by saturating the atmosphere with pheromones released by dispensers. By releasing a large quantity of pheromone into the targeted area, male insects are confused and struggle to locate females, which emit pheromones at a lower concentration than the dispenser. Doing this for an extended period results in less mating and, in turn, fewer eggs and damage-causing larvae. Keeping the population under pressure over an extended period will eventually result in population control.
