Convulsions and climbing behavior: After the fungus enters the ant, it propagates, and fungal cells are found beside the host's brain. Once the population is of sufficient size, the fungus secretes compounds and takes over the central nervous system (CNS), which enables it to manipulate the ant to reach the forest floor and climb up the vegetation.
The ant clamps its jaws around the plant in a "death grip" and following, mycelia grow from the ant's feet and stitch them to the surface of the plant. [9] The spores released from the ant carcass fall to the ground and infect other ants that come in contact with the spores so that this cycle continues. [ 10 ]
The fungus Escovopsis is a parasite in fungus-growing ant colonies that can greatly harm the fungal gardens through infection, [22] and the bacterium Pseudonocardia has a mutualistic relationship with ants. The relationship is thought to have been used by the ants for millions of years, co-evolving to produce the right type of antibiotics.
Fungus-growing ants (tribe Attini) comprise all the known fungus-growing ant species participating in ant–fungus mutualism. They are known for cutting grasses and leaves, carrying them to their colonies' nests, and using them to grow fungus on which they later feed. Their farming habits typically have large effects on their surrounding ecosystem.
Some host specialist entomopathogenic fungi have even evolved mechanisms of behavioral manipulation (e.g. Ophiocordyceps unilateralis - Zombie ant fungus) of their hosts. [7] These fungi hijack the insect nervous systems using various secondary metabolites and manipulate insect behavior to move the infected insect to a place which is ...
Ophiocordyceps myrmecophila, commonly known as the ant fungus or ant eater, [1] is a species of fungus that parasitizes insect hosts, in particular members of the order Hymenoptera. [ 2 ] Distribution
A. sexdens, like all leafcutter ants, is mycophagic. They live in a symbiotic relationship with a fungus belonging to the subphylum Basidiomycota. Leaves and other soft plant material brought into the nest by the foragers is chewed into a pulp and fertilized with faeces. A small piece of fungus is placed on this substrate.
Leucocoprinus gongylophorus is a fungus in the family Agaricaceae which is cultivated by certain leafcutter ants. [1] Like other species of fungi cultivated by ants, L. gongylophorus produces gongylidia, nutrient-rich hyphal swellings upon which the ants feed. [2] Production of mushrooms occurs only once ants abandon the nest. [3]
