Abstract: The physiological development of insect pests is driven by temperature and photoperiod. Geographic variations in the speed of growth reflect current patterns in thermal conditions as a function of latitude and altitude. Global warming will likely lead to shifts in pests’ phenology. Insects are expected to overwinter earlier and develop more generations, with implications for the risks of damage to agricultural crops. Understanding and monitoring of the voltinism of insect pests will be increasingly important to anticipate critical phases of pest development and devise options for adapting pest control measures. In this study, we describe a new generic phenological model that allows to reproduce the voltinism of Lobesia botrana, a major insect pest that affect grapevine production (Vitis vinifera L.) worldwide.
