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,[1] and are agricultural pests in the tropics and subtropics of Africa and Asia.[2]

Nests

Their underground nests form a slight mound above ground, which may be covered in grass.[1] In large colonies, the mounds may be up to 6 m (20 ft) 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.[1]

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.[1] These are plastered with cement where they are obtained, which facilitates diurnal foraging. Odontotermes species are major contributors to litter decomposition.[2] The fungus Termitomyces reticulatus is found in association with O. badius and O. transvaalensis in Africa.[3]

Species

Species include:

  • O. badius worker
  • Cement plastered over tree bark
  • Workers foraging on tree bark under cement
  • Workers in ventilation tunnel
