A basic study of the behavioural responses of the harvester termite, Hodotermes mossambicus (Hagen) to poison baits was undertaken. Laboratory trials revealed that the collected baits were not incorporated into the termite nest food stores. The baits were never eaten because the nest-bound larval caste selects the food to be consumed by the entire colony, from the material collected by the foraging caste. Moreover, field observations have shown that the commercial bait, Kamikaze®, bears no resemblance to the grass collected by the termite foragers. This study revealed that observations of foraging and feeding behaviour of the termites are necessary before designing control measures.
