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.

草莓象鼻虫（Anthonomus rubi）是整个欧洲草莓田的主要害虫。用聚集信息素诱饵的诱集装置用于有害生物监测。但是，需要更有效的诱饵。对于许多害虫，已经表明，宿主植物挥发物可以增强信息素的吸引力。这项研究的目的是探索不同草莓种类（草莓，草莓和草莓）的花香挥发物混合物，以确定可用于提高现有诱饵对SBW的吸引力的化合物。的花香排放F. X一个。变种索纳塔，贝尔特兰，科罗纳和F. vesca通过在Tenax上进行固相微萃取（SPME）和动态顶空进样收集。气相色谱/质谱法分析显示了F. x ananassa的花香挥发物。F. vesca和F. vesca以芳香族化合物和萜类化合物为主，分别由这两个物种产生的主要化合物是4-甲氧基苯甲醛（对茴香醛）和α-茂烯。多维标度分析分离了两种物种的混合物，并解释了vesca基因型之间的差异，以及在一定程度上f。xananassa之间的差异品种在两项选择的行为测试中，SBW比未开花植物更喜欢开花草莓植物的气味，但是象鼻虫没有区别F. x ananassa和F. vesca开花植物的气味。与两种植物相比，向两种非开花植物中添加六种合成花卉挥发物的混合物增加了SBW的偏爱性。当单独添加到非开花植物中时，没有任何一种成分会增加SBW的偏好，表明具有协同作用。然而，SBW对F. viridis挥发物的主要成分1,4-二甲氧基苯有反应，以前在野外研究中发现它可协同SBW聚集信息素的吸引力。
