Figure S2. Aphid behaviour and population size from Indirect ecological effects interact with community genetic effects in a host–parasite system and dramatically reduce parasite burden

Eight clonal aphids from two genotypes (G1 and G2) were placed in 12 different microcosms, each containing four cabbage plants of either red cabbage (R), savoy cabbage (S) or two of each (RS). Six microcosm types were grown on soil that contained 15% onion-trained soil (with inoculum), while six others served as a control (without inoculum). Each of the 12 microcosm types was replicated five times. Average aphid population sizes (± SEM) are shown as rectangles with proportionate border thickness and proportionate varying grades of purple content according to aphid density (population size) across contexts. Aphid behaviour measures as aphid counts on leaves (green), versus stems (orange), versus off-plant (blue) are displayed as parentages in a 10x10 grid. Each square in the grid equals 1%
