Fig. 2. Median P_sol values of the data shown in Fig. 1, obtained after locusts were mechanically stimulated on different regions of the femur as indicated on the x-axis. Values close to 0 indicate that the locusts behaved in a gregarious manner in the assay; values near to 1 indicate that they remained solitarious. Asterisks indicate degree of significance of Dunnet's two-tailed post-hoc tests against the unstimulated controls (white bar): ^*, P<0.05; ^**, P<0.01; ^***P<0.001.
