Analysis of (A) the effect of aphid line on cumulative fecundity (linear mixed model), (B) the effect of resistance to parasitism on cumulative fecundity (linear mixed model), (C) the effect of aphid line on aphid longevity (repeated measures MANOVA), (D) the effect of aphid resistance on longevity (repeated measures MANOVA). Six aphid genotypes were analyzed, three susceptible and three resistant to parasitism. Note: Aphid offspring were not present until day nine. Significant values are indicated with an asterisk. See Figure 2 for graphs of analyses.
