Melolontha cockchafer males search for mates using green leaf volatiles (GLV), released by host plants after female feeding. Thus, the feeding‐induced plant volatiles act as sexual kairomones. Males of both Melontha hippocastani and Melontha melolontha are strongly attracted by the GLV ( Z )‐3‐hexen‐1‐ol ( Z ‐3‐ol). Sex pheromones enhance the attractiveness of Z ‐3‐ol and have been identified as toluquinone (TQ) in M. melolontha , and 1,4‐benzoquinone (BQ) in M. hippocastani . Additionally, phenol acts as a male attractant in both species. From the perspective of potential application, we investigated by field experiments with volatile‐baited traps the ways of enhancing the number of captured males by the use of specific binary or ternary blends of Z ‐3‐ol with phenol, and TQ or BQ respectively. The data show that in both species binary lures containing Z ‐3‐ol combined with TQ or BQ at a ratio of 10 : 1 are the most potent male attractants.
