Figure 2

Locomotor activity patterns of Locusta migratoria nymphs (gregarious phase, Iheya strain) kept with barley leaves (cv. Betzes), wheat leaves (cv. Chinese Spring) or leaves of one of six Betzes chromosome disomic addition lines (2H–7H) of Chinese Spring (see text for details).
One-day-old hatchlings were individually introduced to actograph. Asterisks indicate significant differences from control (Chinese Spring) at each time (Dunnet's test; *p < 0.05, **p < 0.01 and ***p < 0.001). Error bars are omitted from the figure for clarity but shown in Supplementary Table S1.
