The aim of this study is 1°) to quantify environmental changes in herbivory due to Orthoptera on two perennial grasses and 2°) to assess the processes involved in the control of herbivory. Herbivory varies strongly according to shade, drought and mowing, and is positively related to vapour pressure deficit and temperature. Besides the hypothesis of a trophic control of herbivory, our results are consistent with a microclimatic control of herbivory by Orthoptera. The coexistence of different hypothesis of herbivory control may depend on the studied system and specifically on the type of herbivore involved.
