TABLE 3.

Comparison of GAMM models with different sets of predictor variables to predict age‐specific reproductive success of D. suzukii females subjected to different treatments (see Table 1)

Rank	Predictor variables in each model	ΔAIC	Weight
1	Morphotype*Moment of mating	0	1
2	Morphotype	119	0
3	Moment of mating	443	0

Candidate models were ranked from best (rank = 1) to worst fit (rank = 7) according to the Akaike information criterion (AIC). Model weights (Weight) reflect the probability that model i is the best model, given the data and the set of candidate models. ΔAIC is the difference in AIC between the focal model and the model with the lowest AIC score. All candidate models included “vial” as random effect. The predictor variables considered for this analysis were as follows: the morphotype (WM vs. SM), the sex (female vs. male), the moment of mating (pre‐cold mated vs. post‐cold mated), and all possible interactions between these variables.
