Synthetic sex pheromones used were those of the oriental fruit moth Grapholita molesta, the Asiatic leafroller Archippus breviplicanus, and the peach fruit moth Carposina niponensis. Actually no G. molesta were caught when their sex pheromones were placed side by side with those of A.breviplicanus in the same traps. A. breviplicanus was not caught in any of the traps set up. In either of G.molesta and Pammene nemorosa which were frequently caught in the G.molesta traps, curves depicting the trend in the cumulative percentage of daily catches in the summer and autumn did not show significant differences between Japanese pear and chestnut . This fact indicates that the dispersal activities of the males of both species can be traced over wide areas in different environments including chestnut trees, which are not the habitual host plants of G.molesta. It is suggested that in the summer and autumn, G.molesta males invaded extensively the Japanese pear plots studied, which consisted of young trees with a canopy thin. C. niponensis males were caught both in the Japanese pear plots and in a chestnut plot, although the total number of catches was small in all the plots.
