Preference of Pieris brassicae in two-choice tests. For each test, eight different Arabidopsis thaliana pairs were used. Plants grown at a red (R) : far-red (FR) ratio of 2.0 (Control), plants grown at an R : FR ratio of 0.2 (Low R : FR), plants sprayed with 100 μM methyl jasmonate (MeJA) and plants grown at an R : FR ratio of 0.2 and sprayed with 100 μM MeJA (Low R : FR MeJA) were tested. Bars represent the percentage of herbivores that preferred the treatment. Numbers in bars represent numbers of herbivores that made the corresponding choice. Data were analysed with a binominal test. Significant differences: *, P < 0.05; ***, P < 0.001; NS, no significant differences were found for the corresponding choice assays.
