|Publication abstract= The strawberry blossom weevil (SBW), ''Anthonomus rubi'', is a major pest in strawberry fields throughout Europe. Traps baited with aggregation pheromone are used for pest monitoring. However, a more effective lure is needed. For a number of pests, it has been shown that the attractiveness of a pheromone can be enhanced by host plant volatiles. The goal of this study was to explore floral volatile blends of different strawberry species (''Fragaria x ananassa'' and ''Fragaria vesca'') to identify compounds that might be used to improve the attractiveness of existing lures for SBW. Floral emissions of ''F. x a.'' varieties Sonata, Beltran, Korona, and of ''F. vesca'', were collected by both solid-phase microextraction (SPME) and dynamic headspace sampling on Tenax. Analysis by gas chromatography/mass spectrometry showed the floral volatiles of ''F. x ananassa.'' and ''F. vesca'' were dominated by aromatic compounds and terpenoids, with 4-methoxybenzaldehyde (''p''-anisaldehyde) and α-muurolene the major compounds produced by the two species, respectively. Multi-dimensional scaling analyses separated the blends of the two species and explained differences between ''F. vesca'' genotypes and, to some degree, variation between ''F. x ananassa'' varieties In two-choice behavioral tests, SBW preferred odors of flowering strawberry plants to those of non-flowering plants, but weevils did not discriminate between odors from ''F. x ananassa'' and ''F. vesca'' flowering plants. Adding blends of six synthetic flower volatiles to non-flowering plants of both species increased the preference of SBW for these over the plants alone. When added individually to non-flowering plants, none of the components increased the preference of SBW, indicating a synergistic effect. However, SBW responded to 1,4-dimethoxybenzene, a major component of volatiles from ''F. viridis'', previously found to synergize the attractiveness of the SBW aggregation pheromone in field studies.
