Odontotermes
Odontotermes, commonly known as the fungus-growing termites, is a termite genus belonging to family Termitidae, which is native to the Old World. They are most destructive in wooden homes, and are agricultural pests in the tropics and subtropics of Africa and Asia. It is the most diverse termite genus in Africa, with 78 species recorded (as of 2002). Nests. Their underground nests form a slight mound above ground, which may be covered in grass. In large colonies, the mounds may be up to in diameter, and may be covered by shrubs and trees. Some species construct open chimneys  or vent holes that descend into the mound. The fungal garden is enveloped by a thick layer of clay. Castes. The queen is imprisoned in a clay cell in the midst of the fungal garden at the center of the hive. The African species have a single soldier cast, unlike the related genus "Macrotermes". Food. Their only food is the fungus grown in the fungal garden at the center of the nest. The fungus is cultivated on a substrate of wood, bark, leaf litter, dry dung, and dead grass. These are plastered with cement where they are obtained, which facilitates  diurnal foraging. "Odontotermes" species are major contributors to litter decomposition. The fungus "Termitomyces reticulatus" is found in association with "O. badius" and "O. transvaalensis" in Africa. Species.
