Trapping efficacy of lures obtained by mixing sex pheromone attractants of two or three species in a single dispenser were evaluated in peach and apple orchards for three lepidopteran fruit borers, Grapholita molesta (GM), Carposina sasaki (CS), and Conogethes punctiferalis (CP) which use different chemicals as their sex attractants. In the peach orchard, the trapping efficacy of the mixed lures of GM and CS attractants were reduced for GM trapping, compared with the single GM lure. The population fluctuation patterns of GM were highly correlated between the single lure and all the mixed lures. In the apple orchard, the efficacy of all the mixed lures were not reduced for GM trapping. The trapping efficacy of all the mixed lures for CS trapping were not reduced compared with the CS single lure in both the peach and apple orchards. In the peach orchard, the population fluctuation patterns of CS were highly correlated between the single lure and the mixed lures. The efficacy of the mixed lures for CP trapping could not be determined because of the small number of caught samples. The results indicated that mixed lures could be utilized for monitoring of the annual adult emergence of two species, GM and CS.
