Abstract：The oriental fruit moth (Grapholitha molesta (Busck)) is one of the main pests in pear and peach orchards. The effect of the height and trap density on the trapping efficiency of traps baited with the sex pheromones of this insect was determined. The results showed that the best trapping efficiency was achieved when traps were 2 m from the ground in pear orchards, and at 1.5 m from the ground in peach orchards. Trapping efficiency was closely related to sex pheromone density. There was no significant difference in the trapping efficiency achieved by trap densities of 6--10 per 0.067 hm2 in pear orchards but a trap density of 8 per 0.067 hm2 had the best trapping efficiency in peach orchards. These results provide a guide to the control of oriental fruit moths in the field.
