Behavioural responses of C. hircus hircus. (a) S. wertheimae galls and P. atlantica leaves were offered either intact or slightly wounded. Time spent assessing each odour by olfaction was recorded. Boxes depict medians and quartiles, whiskers and dots show extreme values and outliers, respectively. Asterisks indicate significant differences at P < 0.05 (Wilcoxon Matched Pairs tests, n = 10; intact: Z = −2.803, P = 0.005; wounded: Z = −2.601, P = 0.009), wounding had no significant effect (Bonferroni-corrected α = 0.025) on the duration of sniffing (galls: Mann–Whitney U test, U = 24.50, P = 0.053; leaves: U = 39.50, P = 0.427). (b) Consumption of food pellets treated with α-pinene, sabinene, and limonene. (Student’s t-test for pairs, t = 3.475, P = 0.007).
