[Objectives]  In order to clarify how four generations of Grapholita molesta select oviposition sites on different host plants. [Methods]  The oviposition preferences of gravid females for the tender shoots and fruits of different hosts, including peach, pear and apple, were determined under laboratory conditions. [Results]  Different generations of gravid females had significantly different oviposition site preferences. Overwintering, second, and third, generation females preferred pear fruit and peach shoots, whereas the first generation females preferred peach and pear fruits. Apple shoots and fruits were the least preferred oviposition sites. Egg hatching and laying rates were consistent with female oviposition preferences. Although the egg hatching rates of different generations on pear fruits differed significantly, there were no significant differences in the egg hatching rates of different generations on other host fruits or host shoots. [Conclusion]  Peach shoots only attract first generation females whereas pear fruits attract the other three generations of female moths and consequently contain more fertile eggs. Different generations of female Grapholita molesta differ in their oviposition preferences in order to ensure a superior econiche for their offspring.
