Implementation of mating disruption (MD) of codling moth is reviewed from early pioneering small plot trials to large-scale areawide initiatives from multiple continents for a range of pheromone delivery devices. Biological and economic drivers facilitating the success of areawide codling moth MD will be discussed as well as factors limitings its rates of implementation. The transition from replicated small plots, which potentially trade off plot independence to achieve greater statistical rigor, to larger demonstration plots which lack the same statistical rigor is discussed. The logistical and social challenges associated with large regional initiatives include management structure as it relates to top-down or bottom-up oversight, coordination of information, management of risk and expectations, and navigation of political conflicts.
