Table 1 Results for four-factorial significance tests (df, degree of freedom) with the independent factors species (Aedes albopictus, Culex pipiens), food regime (3 and 6 mg larva^-1 food supply), larval ratio (0, 10, 15 and 20 larvae of the other species) and temperature (15, 20 and 25 °C). The dependent variables mortality (arcsin log-transformed) and female/male PT₅₀ (log-transformed) were tested with a general linear model (ANOVA, F value) whereas the effect variables female/male abdominal length (AL), dry weight (DW) and biomass accumulation (BA) were tested with a general linearized model (normal-log model with backward removal, Wald value)
