Abstract

The Proeulia auraria mating disruption (Lepidoptera: Tortricidae) using synthetic copies of the sex pheromone of the female insect, a mixture of two components E-tetradecyl acetate (E11-14: OAc) + E-11-tetradecanol (E11-14: OH), it was evaluated in orchards infested vine, apples and blueberries using the formulation SPLAT (Specialized Pheromone Lure Application and Technology). In terms of g pheromone and number of stations / sources 0.1 has been tested: 7.8 g in 25 sources, 7.8 g in 75 sources, and 29.5 g in 25 sources in vineyards; and 2.6 g in 25 sources (blueberry) and 75 sources (apple). All trials considered a witness without pheromone (control) and recorded weekly catches of adult male P. auraria Delta traps. In all treatments there was no P. auraria. Catches during the first three weeks, after application of SPLAT, compared with the control group (without pheromone), showing significantly higher catches. These results show a high percentage (100%) of disruption, however it must be confirmed in time and should be supplemented with assessments of damage to the foliage and fruit crops.
