Field trials were conducted to determine whether the peachtree borer (PTB) Synanthedon exitiosa (Say) could be reduced with traps baited with its snythetic sex pheromone, (Z,Z)3,13-octadecadien-l-ol acetate (Z,Z-ODDA). Traps were evaluated at 2.5 traps/ha and 5 traps/ha in 2 peach orchards; one with a high PTB infestation, the other with a low infestation. Results showed the 5 traps/ha were more effective than 2.5 traps/ha but both treatments gave better PTB control than the conventional insecticide treatment regardless of insect density.
