The six male traits are mean time to emerge, mean wing length, the proportions of inseminated, motile sperm bearing, and ovipositing females, and the mean number of eggs per batch. Each male trait is modeled as a two-way ANOVA of block (black versus red), male genotype (refractory versus susceptible) and their interaction. Shown are the degrees of freedom (df), sum of squares (SS), mean squares (MS), the F-statistic (F), and the p-value.
