Il sistema di confusione sessuale "Puffer® CM" per la difesa della carpocapsa del melo

Some techniques have been developed to achieve mating disruption (MD) of Codling moth (CM), by treating orchards with controlled release devices or by sprayable pheromone. In Trentino MD has been adopted successfully (6,400 ha, i.e. 50% of the apple area) to control CM in heavily infested areas; on the contrary in areas with low pressure of the pest, usually less pesticides are applied and till now pheromone applications were considered economically not convenient. A new pheromone-based control technique, called Puffer®, has been recently proposed and it is under evaluation by Fondazione Mach Centre. Puffer, manufactured by Suterra LLC use a cabinet to automatically dispense the CM pheromone. The ease and low time consumption in applying pheromone, due to the low numbers of cabinet per hectare, are the major factor of interest for growers
