Individual termites follow a simple rule for tunnel excavation, but the emergent outcome of tunnel structure produced by a group of termites exceeds the collective sum of the individual efforts. Foraging gallery of a colony is made up of numerous emergent outcomes of groups of termites, but its growth is dictated by the environmental restrictions and inter- and intra-specific competitions. Simulation results based on empirical data at individual, group, and colony level will be presented, and their use for predicting the population recovery following an area-wide population management program will be discussed.
