Novel pheromone delivery system to reduce codling moth (Cydia pomonella L.) damage in organic pome fruit orchards (BIOFRUITNET Practice Abstract)

New pheromone delivery system can increase the control effectiveness, reduce labour costs and plastic waste from dispensers. Practical recommendation • To achieve a high efficacy, the orchard size should be more than 3 ha. Puffer can be a good solution to re-duce labour costs and the burden due to plastic waste from dispensers, but in sites with not too much wind exposition. • Two kinds of dispensers should be introduced into the orchard before the beginning of CM flight. • Hang the plastic dispensers (Picture 3) on every third tree or apply the “dots” (Picture 4) every 3-4 m on the border rows of orchard trees and at the beginning and end of each row (at two thirds of the tree height) (Picture 2). • Place 2 aerosol dispensers per ha inside the orchard. These “puffer” (Picture 5) units should be hung on poles above trees, at about 3.5-4.0 m height. • Install delta traps, 3 per orchard (Picture 1), for monitoring the presence of adult CMs during the season. They should be placed halfway between consecutive “puffer” units. If the strategy of mating disruption works well, no moths should be found in the monitoring traps during the entire season
