  1. A: summary of results from a three-factor mixed model ANOVA on mean larvae to the adults development time of females using selection (FCB and FSB) and treatment (cold shock and no shock) as fixed factors crossed with the random block (1–5). B: summary of results from a three-factor mixed model ANOVA on the mean larvae to the adults development time of males using selection (FCB and FSB) and treatment (cold shock and no shock) as fixed factors crossed with the random block (1–5)
