Abstract：The oriental fruit moth (Grapholitha molesta (Busck)) is an important global pest of fruit trees. Sex pheromone bottle traps have been widely used to control this pest in orchards. In order to determine the most efficient trap design, we tested the relative effectiveness of bottle traps with four openings on each side vs those with two opposite openings, and pore sizes of 2 cm, 3 cm, 4 cm, 5 cm and 6 cm. The results show that traps with 2 opposite openings worked better than those with four and that the most effective traps had pore sizes of 2 cm and 3 cm. The daily average catch achieved by traps with pore sizes of 2 cm and 3 cm was 34.6 and 20.6, which was significantly more than that of traps with 6 cm pores. Therefore, we suggest that traps for the Oriental fruit moth should have two opposite openings and a pore size of 23 cm. These results provide a basis for improving the control of OFM in orchards.
