Colonies of Trinervitermes geminatus (Wasman) build a network of forked foraging trails. Homing workers choose, with few exceptions, those tracks at the forks of the pheromone trail network that lead direct to the nest. Assessments show that these wo

Polyethism in food processing and the social organisation in the nests of Macrotermes bellicosus field colonies were investigated by characterising the gut contents and the labial glands (dry weight and protein content) of workers. Workers from three

The existence of caste-specific pheromone trails in the two worker castes of Macrotermes bellicosus, as assumed from earlier work, was investigated in the laboratory by means of a previously developed parallel trail testing device.¶Foraging trails,

In the galleries of Macrotermes a differentiated effect of communication was observed, by which the outward running termites could apparently distinguish between going to a feeding place or to virgin ground of exploration. The aim of this study was t

The system of underground passages and storage pits used in foraging have been excavated in two nests of the termite Macrotermes subhyalinus in West Africa (Ivory Coast). A detailed qualitative description of the morphology and the dimensions of the

Age polyethism and total activity of M. bellicosus were investigated by using a newly developed marking method in combination with metal and photo detectors. Running activity to and from the queen cell and through the nest exit into a food arena were

Intraspecific colony recognition in the termites Macrotermes subhyalinus and M. bellicosus was investigated over two field seasons in Comoe-Nationalpark (Ivory Coast). Behavioural tests with major workers and minor soldiers, respectively, were perfor

A sophisticated system of vibrational long distance alarm communication was found in the African fungus growing termites Macrotermes bellicosus and M. subhyalinus. When disturbed in their nests and in their extended gallery systems, soldiers produce
