Abstract:		"For successful pest management, codlemone (E, E-8,10-dodecadien-1-ol) is widely used to monitor codling moth. The pheromone release rate is essential for the lure's attractiveness. The optimal sex pheromone release rate (V0) for trapping codling moth was evaluated during 2013-2014. The overwinter generation V0 was 6.7-33.4 mug wk(-1), and moth catches (MCs) were 0.82 +/- 0.11 adults/trap/week; MCs for lower (V1) and higher (V2) release rates were 52.4% and 46.3%, respectively, of that for V0. The first generation V0 was 18.4-29.6 mug wk(-1), with MCs of 1.45 +/- 0.29 adults/week/trap. V1 and V2 MCs were 34.5% and 31.7%, respectively, of those for V0. Combining across generations, the final V0 was 18.4-29.6 mug wk(-1), with MCs of 1.07 +/- 0.06 adults/week/trap. V1 and V2 MCs were 51.4% and 41.1%, respectively, of that for V0. Overwinter generation emergence was relatively concentrated, requiring a wider V0. Maintaining the release rate at 18.4-29.6 mug wk(-1) could optimize the lure's efficacy; this resulted in the capture of nearly 1.9 and 2.4 times more moths than V1 and V2, respectively. The results also indicate that a dispenser pheromone release rate of 200-300 times that of the female moth can perfectly outcompetes females in the field"
