Abstract:		"Codling moth (Cydia pomonella) is one of the most important pests in apple and pear. In 2010 mating disruption became a key pest management tactic in Flemish pip fruit orchards, largely due to a government subsidy and demonstrating projects aiming to widen the area treated by pheromones as large as possible. As a consequence, the mating disruption strategy was applied at approximately 7.500 ha, or half of the pip fruit area, in 2010 and 2011. The sudden large-scale implementation of this technique changed the codling moth management landscape. Here we present a case study of a commercially managed orchard that suffered from high codling moth pressures for many years, as did the surrounding area. The RAK3 mating disruption system was introduced at this location in 2010, and was continued in 2011. Systematic detailed codling moth flight data for this location are available for many years. In addition, comprehensive data on damage levels of chemically untreated windows spread all over the test orchard in a randomized block design were obtained in successive years, enabling us to thoroughly evaluate the effect of the changed codling moth management strategy. Data from 2011 included damage levels in chemically treated windows when the entire orchard was applied once at the flight peak of Cydia pomonella. In 2009, before introduction of mating disruption, a mean of 8.25 +/- 5.54% of the fruits were infested at harvest when assessed in completely untreated windows. After two years of mating disruption, supported with a full chemical support in 2010, except for the untreated assessment windows, and only one application on the flight peak of 2011, damage was reduced to less than 0.03% at harvest. This is a valuable case study to demonstrate the benefits of the mating disruption approach"
