From: Evaluation and modeling of synergy to pheromone and plant kairomone in American palm weevil

Figure 1

Responses of American palm weevils (n = 20 ± 2 males + females) in a 4-arm olfactometer to seven doses of synthetic aggregation pheromone (2-methyl-(5E)-hepten-4-ol) and seven doses of fermented sugar cane odor (kairomone) delivered at constant flow rates by the volatile delivery system. a - Mean (± standard error) time spent in pheromone (plain large circles) or kairomone (thin open circles) arm during a 10 min test (*: different from control arms; Dunnett test, p-value < 0.05; straight line at 145 s: residence time in one arm in the absence of effect). Modeled responses to pheromone (RP) and to kairomone (RK) shown as a bold line and a thin dotted line, respectively. Arms entered first (first choices): b - with pheromone and c - with kairomone; significant with: *: p-value < 0.05; **: p-value < 0.01 and ***: p-value < 0.001 (binomial tests). Doted line at 25%: random choice.
