Abstract  [Objectives]  To identify the kinds of oviposition sites preferred by Grapholita molesta (Busck) in peach orchards. [Methods]  The distribution of eggs in different parts of peach trees was systematically investigated. [Results] 1. Spatial preference: 91.36% of eggs were laid in the middle and upper parts of the tree crown. This preference was the same for overwintering generations and 1st to 4th generations. There was a significant preference for the periphery of the tree crown, especially in the fourth generation, which laid 97.32% of all eggs in the crown periphery. 2. Aspect: 1st to the 4th generations of the overwintering generation preferred the eastern side of the tree crown, but no significant preference was apparent among the other generations. 3. Accurate location bias: 92.52% of eggs were single eggs laid on leaves. The overwintering generation preferred open leaves and laid 93.33% of eggs on these. The 1st to 4th generations preferred the 1st to 15th leaves; 80.00% of eggs were laid on these. The 1st to 3rd generations laid > 50.00% of eggs on the 3rd to 8th leaves. All generations tended to lay on the abaxial leaf surface, on which 97.37% of all eggs were laid. [Conclusion]  G. molesta has clear preferences for specific oviposition sites in peach trees. More than 90% of eggs are laid in the middle and upper parts of the tree crown and on dorsal surface of peripheral leaves. A single egg is laid on each leaf. These results provide useful information for developing accurate, efficient and environmentally-friendly, monitoring and control measures for G. molesta at the egg stage.
