对流层中的空气污染物，特别是臭氧（O3）的浓度自工业化前以来急剧增加。由于O3的强氧化潜力，植物挥发性有机化合物（VOCs）在大气中的排放和寿命的负面影响已经被强调。O3改变VOCs可能会影响依赖这些化学信号的传粉者的吸引力。令人惊讶的是，O3对嗅觉和传粉者的行为反应的直接影响还没有调查到目前为止。我们开发了一个全面的实验，在受控条件下，以评估O3的生理和行为的影响，两种传粉者，不同的生态特征。使用几个现实浓度的O3和各种曝光时间，我们调查了气味触角检测和吸引挥发性有机化合物存在于其相关植物的花香。我们的研究结果表明，在这两个物种中，暴露于高浓度的O3的能力，以检测和反应的花挥发性有机化合物的一个明确的效果。这些影响取决于测试的挥发性有机化合物及其浓度，以及O3暴露（浓度和持续时间）的传粉物种。因此，授粉系统可能会以不同的方式受到O3水平增加的损害，其影响可能取决于暴露是否是慢性的，或者如本研究所述，准时的，可能导致一些授粉系统比其他系统更脆弱。虽然一些研究已经表明O3对大气中VOCs排放和寿命的负面影响，但这项研究首次揭示了这种影响会改变传粉者的检测和行为。这些发现强调了在评估对传粉者的威胁时迫切需要考虑空气污染。
Concentration of air pollutants, particularly ozone (O3), has dramatically increased since pre-industrial times in the troposphere. Due to the strong oxidative potential of O3, negative effects on both emission and lifetime in the atmosphere of plant volatile organic compounds (VOCs) have already been highlighted. VOCs alteration by O3 may potentially affect the attraction of pollinators that rely on these chemical signals. Surprisingly, direct effects of O3 on the olfaction and the behavioral response of pollinators have not been investigated so far. We developed a comprehensive experiment under controlled conditions to assess O3 physiological and behavioral effects on two pollinator species, differing in their ecological traits. Using several realistic concentrations of O3 and various exposure times, we investigated the odor antennal detection and the attraction to VOCs present in the floral scents of their associated plants. Our results showed, in both species, a clear effect of exposure to high O3 concentrations on the ability to detect and react to the floral VOCs. These effects depend on the VOC tested and its concentration, and the O3 exposure (concentration and duration) on the pollinator species. Pollination systems may, therefore, be impaired in different ways by increased levels of O3, the effects of which will likely depend on whether the exposure is chronic or, as in this study, punctual, likely causing some pollination systems to be more vulnerable than others. While several studies have already shown the negative impact of O3 on VOCs emission and lifetime in the atmosphere, this study reveals, for the first time, that this impact alters the pollinator detection and behavior. These findings highlight the urgent need to consider air pollution when evaluating threats to pollinators.
