Macrotermes natalensis

Macrotermes natalensis is a fungus-growing termite species, which belongs to the genus Macrotermes, commonly reported in South Africa. This species is associated with the Termitomyces fungal genus. M. natalensis has domesticated Termitomyces to produce food for the colony.

M. natalensis has become a well-studied fungus-growing termite species, and its genomic sequence reads generate 1.3 gigabytes of data, making it the largest insect genome to date.[2]

Colony caste system

All the fungus-growing termite colonies similar caste systems. Each caste plays a different roles in the colony, but it is not yet known how caste selection occurs. The primary reproductive caste or royal pair is made up of a king and a queen. The winged alates make up the secondary reproductive caste. Sterile castes do not possess any reproductive capacity and include workers and soldiers, both major and minor.

Termitomyces in a colony

Termitomyces fungi play a major role in termite nutrition. They also influence termite survival and caste development. The fungal garden is managed by the worker caste.

In a mature M. natalensis colony, older workers collect dead plant material along with Termitomyces asexual spores from their habitat and pass these on to the younger workers. The young workers only stay in the nest. They receive the plant material and ingest it along with the Termitomyces spores. Later, young workers defecate this blended plant material, along with fungal spores, somewhere in the colony nest. It forms a "comb", where the fungal mycelium establishes a dense network. The Termitomyces fungi use the nutrients from the comb and complete their life cycle with fruiting bodies or fungal nodules.

gollark: Platypi are highly anomalous. They can also sense electric fields.
gollark: Did you know? In 2020, research in biofluorescence revealed that the platypus glows a bluish-green color when exposed to black light.
gollark: As planned.
gollark: I made a hilarious meme to express this.
gollark: Amazing.
