Technical Abstract: Novel control methods, using both sprayable microencapsulated formulations (MEC) and hand-applied (HA) dispensers, have demonstrated that the pear-ester (PE) attractant kairomone (ethyl (2E, 4Z)-2,4-decadienoate), termed 'DA'-kairomone, improves mating disruption (MD) of male codling moths (CM) in both walnut and apple orchards of California. MD treatment blocks compared pheromone alone vs. pheromone + PE kairomone, using both hand applied dispensers and MEC spray tactics. Pheromone trap capture was 'shut-down' (>90%) in all pheromone-treated blocks with and without PE adjuvant. Percentage of female multiple-mating was decreased by the addition of PE adjuvant to pheromone MD. For both MEC spray and HA, percent harvest damage in MD blocks was generally decreased by the inclusion of the PE adjuvant with the pheromone disruptant.
