Notes: F values from mixed effects model analyses of variance for the effects of Family (a random factor), Cross (inbred/outbred), Spray Treatment (weekly insecticide spray or no insecticide spray), and the two-way interactions of Family by Cross, Family by Spray Treatment, Cross by Spray Treatment and the three-way interaction on 9 individual and 3 cumulative components of fitness. F values were generated by Type III sums of squares from a general linear model (Proc GLM, SAS Institute, 2002).
