Age at pupation, emergence and adult death decreased with increasing temperature (Additional file 1: Figure S3). The first pupation occurred in males on day eight at 26 °C to 29 °C. One day later, females started to pupate. At the lowest experimental temperature where emergence occurred (10 °C), pupation started later than at day 40 (Additional file 1: Table S2). Age at pupation and age at emergence were significantly affected by temperature treatment (Fpup(3,2466) = 11,043.6, Ppup ≤ 0.001; Fem(3,2466) = 10,448.6, Pem ≤ 0.001) and sex (Fpup(3,2466) = 27.8, Ppup ≤ 0.001; Fem(3,2466) = 14.2, Pem ≤ 0.001) while age at adult death was significantly affected by sex (F(3,2457) = 53.7, P ≤ 0.001), temperature (F(3,2457) = 12,614.0, P ≤ 0.001) and their interaction (F(3,2457) = 14.4, P ≤ 0.001). For all three parameters, temperature explained more than 80% of the variance. With these data, we estimated the generation time with a nonlinear model to the age of emergence at different temperatures:
