We review the mechanisms at play in the responses of planteinsect interactions to global changes, including increased temperature and atmospheric CO2 concentrations, modification of land use and pollution. We distinguish between the direct effects of global changes on each partner from the indirect impacts on insects via the responses of plants. The indirect effects include a change in the nutritional quality of the plant tissues for herbivore insects, as well as a change in the microclimatic conditions at the leaf surface. Pollinators are involved in a close symbiotic relationship with their favourite plants, and any depression caused by climate stress can lead to pollination deficit. Pollinators are, indeed, quite sensitive to global changes. Furthermore, although species are connected by trophic links, all species respond differently to global changes. We highlight that more research is needed to elucidate the plant-mediated indirect effects of climate change on insects. Then, other human activities, such as land transformations and release of pollutants, are likely to modulate these links between climate and plant-insect relationships. We argue that predicting the net effect of global change on planteinsect relationships requires a comprehensive understanding of the mechanisms that modulate the interaction strength between the plants and the insects, rather than on focusing on each partner individually. specialized 076 Sauvion N. ed. edt IRD Thiéry D. ed. edt IRD Calatayud Paul-André ed. edt IRD 81 289-332 Londres Elsevier 2017 81 https://www.documentation.ird.fr/hor/fdi:010069888 10.1016/bs.abr.2016.09.009 978-0-12-803318-0 [F A010069710] https://www.documentation.ird.fr/hor/fdi:010069888 https://www.documentation.ird.fr/intranet/publi/depot/2017-07-11/010069888.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-07-11 2023-07-11 fdi:010069888 fre
