Such a method consists in the setting up of several prevailing pheromone trails, released by an appropriate number of dispensers loaded with low pheromone dosage, able to compete with those of the female insect and thus disorientate males in their search for partners. The soundness of the disorientation method has been demonstrated through experimental and large-scale demonstrative trials, covering more than 200 hectares of peach orchards and 32 hectares of pome-fruit orchards located in several Italian regions in 1998-99.Specific, biodegradable, pheromone dispensers, named Ecodian, numbering 2000/ha for a total amount of 20 g active ingredient per hectare, were used for each application, which had an average duration of 45-50 days. In peach orchards, in 1998 damages lower than 5% were registered on 159 of the 186 demonstration tests (81%), against 186 of the 209 tests (89%) in 1999. Damages less than 1% were registered in 74 tests in 1998 and 119 tests in 1999. In pome-fruit orchards, the dispensers for Cydia molesta were applied in mid-July on fields where, for the most part, the mating disruption was practiced with Ecopom Isagro dispensers for the defence against Cydia pomonella. Of the 22 demonstration trials in 1998, only 1 suffered damage of 2%, while in the other 21 the control was total. An excellent control of Cydia molesta was also achieved in 1999, only 1 out of the 31 tests suffered damage higher than 5% (mainly due to the border effect) while in 24 tests the attack was kept within 1%.
