Fig. 5. Effects of serotonin antagonists on the behavioral response of the male
moth to different concentrations of artificial pheromone. 4 µl of the drug
were applied to the desheathed brain 3 min before pheromone exposure. Both
drugs shifted the curve to the right (GLM, P<0.05), decreasing
significantly the behavioral response in comparison with the control. (A)
Mianserin at 10-4 mol l-1. Sample size: control
(N=65), mianserin (N=64), wash (N=60). (B)
Ketanserin at 10-3 mol l-1. Sample size: control
(N=84), ketanserin (N=82), wash (N=34).
