Descrição: Aphid attacks and tropospheric ozone (O₃) cause stress and considerable damage in both wild and cultivated plants. Induced defense responses to aphid attacks and O₃ exposure share signaling pathways with common points. We investigated the plant-aphid interaction under O₃ exposure using open-top O₃ chambers. Ozone leaf injury was lower in aphid-infested plants than in aphid-free plants, although herbivore damage was not evident. Aphid population growth was strongly affected by previous exposure to O₃ but no direct effect of O₃ was observed. The possibility that during O₃ episodes, herbivores may reduce O₃ damage on host plants and that the offspring of the exposed aphids have lower population growth rates opens new and intriguing questions about potential effects of future increased tropospheric O₃ levels on plant-insect interactions.
