| Abstract: | Visual and nonpheromone olfactory orientation processes of the giant tropical ant Paraponera clavata were investigated in homing foragers which had been previously trained to visit a food source. Experienced foragers can select directions visually, with pheromone trails (Breed et al., 1987), or with environmental odors. High-contrast canopy cues, but not low-contrast lateral landmarks, serve as strong visual orientation cues. |
