Abstract

Studies were conducted to compare the effect of trap placement above and below sex pheromone mating disruption (MD) dispensers on captures of codling moth, Cydia pomonella (L.), and oriental fruit moth, Grapholita molesta (Busck), in apple orchards. Traps were placed at a height of 1.8 m or 4.5 m in the tree canopy whereas MD dispensers were placed at 3.1 m within the tree canopy; an adjacent set of plots were treated similarly with only insecticides (nonMD). All trees were approximately 4.8 - 5.1 m in height. Capture of codling moth adults in traps was highest in traps placed at 4.5 m in both MD and nonMD plots and lowest in traps placed at 1.8 m in MD treated plots. Reduction in adult codling moth capture was low to moderate (< 64%) in traps placed above dispensers and higher (>70%) in traps placed below dispensers over both years. Oriental fruit moth adult capture in 2007 was lowest in traps placed at 1.8 m in plots treated with MD. In 2008, capture of oriental fruit moth was highest in traps placed at 4.5 m.
