Optimized trap lure for male Melolontha cockchafers
Journal of Applied Entomology 130 (3), 171-176
Abstract: 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 Melolontha hippocastani and Melolontha 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.
