This thesis assess impacts of warming temperatures on future Grapevine (Vitis vinifera) and one of its major insect pest known as grapevine moth (Lobesia botrana)synchrony. The phenology of both trophic levels has already changed over the last decades in response to increases in temperature, with a tendency towards earlier development. The impact of rising temperatures could alter phenology and lead to unequal shifts within food chains, being either beneficial or detrimental to host plants. The pressure for reducing the use of chemicals in conventional agriculture is getting stronger in the last decade. Biocontrol by targeting the eggs of other insects is an efficient alternative to pesticides. This study aimed at understanding how L. botrana will evolve with respect to both its lower (V. vinifera) and upper (Trichogramma Spp.) trophic levels under warmer conditions in the future, considering the forcing pathways RCP4.5 and RCP8.5, at European scale, by the means of generic phenological models.
