Effects of immunostimulation on the relative proportions of cuticular hydrocarbons. Discriminant analysis was performed on the cuticular chemical profiles of control, saline-, bead- and bacteria-injected individuals, based on the relative proportion of each compound. There were significant differences across treatment groups in (A) Colony 1, F(39, 113)=4.9032; p<0.0001), all Mahalanobis distances, p<0.01, and (B) Colony 2, F(12, 108)=2.004; p<0.05, all Mahalanobis distances, p<0.05, expect for differences between saline and beads injected individuals, which were p=0.4.
