The oriental fruit moth (Grapholita molesta) and the plum fruit moth (G. dimorpha) share the same major sex pheromone components, Z8-dodecenyl acetate (Z8-12Ac) and E8-dodecenyl acetate (E8-12Ac) with different ratio. However, these two congener male species were cross-attracted to the counter sex pheromone traps. For development of the specific monitoring lures, the minor sex pheromone components were added to the major components. G. molesta females emit two minor components of Z8-12OH and 12OH and G. dimorpha females emit four minor of 12Ac, 14Ac, Z8-14Ac, and E8-14Ac. For a specific monitoring lure of G. molesta, only Z8-12Ac major component attracted only G. molesta males, but did not any G. dimorpha. For a specific monitoring lure of G. dimorpha, the addition of Z8-14Ac to the major component (Z8-12Ac:E8-12Ac = 85:15) attracted G. dimorpha males with less than 5% G. molesta males. Other with components (12Ac, 14Ac, and E8-14Ac) was not effective in both trapping efficiency and selectivity.
