Proportions of mummies off-plant subject to intraguild predation (IGP). Percentages of aphid mummies (means ± SE) recorded off the plant are shown for N116 and Q1 exposed to the effect of the parasitoid genotype (daughters) in the absence of IGP (dark grey) and the presence of IGP (light grey). Sample sizes were as follows: In the absence of IGP: n = 20 parasitoid daughters in the case of N116, and n = 29 in the case of Q1. In the presence of IGP: n = 19 parasitoid daughters in the case of N116, and n = 13 in the case of Q1. In total there were 81 parasitoid daughters. The smallest uniform rectangles shown in the detailed illustration refer to the off-plant mummy proportion of 0%. The parasitoid genotype (daughters) were the result of the Sire × Dam mating system (quantitative genetic design)
