An estimated 15,408 immature and 2588 adult T. vaporariorum /day were removed from Lantana camara plants by S. invicta . Mean rates of movement of ants on the foraging trail ranged 1.96–2.31 cm/sec., and speeds of host-carrying and non-host-carrying ants were not significantly different. Foraging activity was maintained 24 h/day.
