Fig. 7. Percentage of simulated male trajectories resulting in a mating encounter with a female, i.e. coming within 3 cm of a virtual female located on the pheromone trail. The female is located 20 cm to the right of the closest point of the trail from the simulated male. The male starts 5 cm from the trail, so that the female is at an angle of 15° from the male (see inset), where 0° is parallel to the pheromone trail, to the right. The simulated male was `launched' 20 times at each angle, in 5° increments. (A) Percentage of trajectories out of 20 at each launch angle resulting in a mating encounter. (B) Overall percentage of trajectories (out of a total of 720 at all angles) resulting in mating encounters. ANOVA, P<0.001; ^*P<0.05, pairwise Tukey's test, compared to control.
