When ants were experimentally excluded for 6 months from mature and immature foliage of saplings of E. incrassata in South Australia, no significant differences in herbivory were found between ant-access (AA) and ant-excluded (AE) treatments. Eurymelid bug densities decreased rapidly in AE treatments compared with AA. Ants also quickly removed seeds of E. incrassata from experimental caches. The potential of ants to reduce the density of insect herbivores on eucalypts seems limited.
