Phenological models for insect pests often rely on knowledge of thermal reaction norms. These may differ in shape depending developmental conditions (e.g. constant vs. fluctuating) and other factors such as stage endosymbionts. Here, we conducted an extensive comparative study the norms development viability invasive fly, Drosophila suzukii, under fluctuating regimes. Flies, infected or not with Wolbachia, were submitted to 15 different temperatures (CT) ranging from 8 35 °C. We compared responses CT patterns observed (FT). tested several equations performance curves various obtain limits degree-day estimations. To validate model's predictions, phenology was monitored two artificial field-like natural outdoor cages during spring winter. Development rates mostly similar flies Wolbachia. Thermal norm egg pupae larger than that adult. FT yielded a breadth CT, extended towards colder side, consistent our field observations Models resulting both made accurate predictions long temperature remained within linear part rate curve. Under cold winter conditions, model based data more predictions. Model failed predict adult's emergence also document first time successful adult throughout Population dynamics D. suzukii are all summer morphotype CT. Accounting variations between morphotypes, stages, (CT FT) could improve predictive power models.
