Some techniques have been developed to disrupt mating (MD) of codling moth (CM) by treating orchards with pheromone. Synthetic pheromone is applied to the crop as a formulation that is designed to protect these generally labile compounds from degradation while gradually releasing pheromone into the atmosphere. In Trentino South Tyrol MD has been adopted successfully (24,500 ha, i.e. 73% of the apple area) to control CM in heavily infested areas; while in areas with low pest pressure, less pesticides are usually applied (2-3 per year) and as a consequence, pheromone mating disruption is not considered economically convenient. Hand applied sealed plastic tubes and plastic ampoules are the two pheromone formulations more widely used. A new pheromone-based control technique, called Puffer, has been recently proposed. Puffers are battery-powered devices that release pheromone from pressurized aerosol cans every 15 minutes for 12 hours or 30 min for 24 hours. During each puff a quantity of 6.95 mg a.i. is emitted. The high release rate of pheromone per puff from aerosol dispensers is thought to compensate for their low application densities (2-2.5 puffer/hectare). Results of three year field trials carried out in Trentino-South Tyrol demonstrated the potential of Puffer as effective tool to control the moth.
