Effect of Ambrosia artemisiifolia and Ophraella communa genotype on Ophraella adult emergence (survival up to adults; up left), death stage (stage when died; up right), total developmental time (L1 to adult, gray cells indicate tests without adults emergence); bottom left), and on leaf area eaten during L2 and L3 instar (bottom right). Blank cells represent missing data. Dark-colored horizontal line means that the interaction is driven by the Ophraella genotype, dark-colored vertical line means that the interaction is driven by the Ambrosia genotype.
