Ants may spread sapsucker infestations between plants via underground tunnels. These findings suggest that the context dependency of ant‐aphid mutualism can be an important factor affecting the pattern of ant abundance and plant herbivory across the elevational gradient.

Aphid numbers drop by 88 percent when their tree habitats are located more than six meters from an ant mound. While many studies have demonstrated that ants provide beneficial services to aphids, Bristow (Ant-plant interactions, Oxford University Press, Oxford, 104–119, 1991) first questioned why so few aphid species are ant-attended. The ants may move the insects to areas on the plants with the best sap. Main Menu . Some species of ants farm aphids, protecting them on the plants where they are feeding, and consuming the honeydew the aphids release from the terminations of their alimentary canals.
