A fungus-growing ant from the genus Trachymyrmex, the closest living relatives of leaf-cutter ants, tending to a fungal garden.
A 15-year study of leaf-cutter ants and their relatives across North and South America found that their nests are susceptible to infection by a diverse group of specialized fungal parasites. The study, which is available online in Royal Society Open Science, is one of the largest ever undertaken of parasites associated with leaf-cutter ants. Leaf-cutter ants inhabit areas from the southern United States to Argentina, and there are at least 40 species, including the Texas native Atta texana, which is found only in Texas and Louisiana.
In Texas, the ants are known to damage citrus, plum, peach and other fruit trees, nut and ornamental plants as well as some forage crops. Solomon began collecting leaf-cutting ants and their fungi in Central America in 2002 as a graduate student working with UT-Austin's Ulrich Mueller, a co-author on the study. To collect samples, the team traveled across much of Brazil in search of leaf-cutter ants and their relatives.
Leaf-cutter ants are well-known examples of insects that use microbes to gain access to nutrients, farming "gardens" in which bacteria and fungi break down plant mass.
The nests are so large that they build their own ventilation systems to maintain a constant flow of fresh air fresh for the ants and fungus growth. Leaf cutter ant queens are typically 30mm length, they are dull brown, very chubby, and are monogyn (one queen per colony).
Approximately only 10% of leaf cutter queens in actually go on to reign a successful colony when raised in captivity.
Dufour’s gland – is believed to be involved with the laying of chemicals that guide other ants and perhaps the attraction of mates. Gamergates – rare female worker ants which can mate and reproduce, keeping the colony alive after the queen dies. Hymenoptera – the Order in which ants occur, the Order also includes bees, wasps and sawflies. Major worker – the larger worker ants found in a colonies caste, also known as soldier ants.


Mandibles – the ants main jaws, these are used for cutting, holding, fighting, and digging. Median workers – worker ants found in polymorphic species that are sized between minor and major workers. Nantics – first born ants that tend to be smaller than typical established colony workers.
Rectum – holds the waste products inside an ant, waste will be deposited in the colonies designated waste area.
Repletes – a caste of ant that stores large amounts of liquid food in its crop i.e honey pot ants.
Trophallaxis – The ‘mouth to mouth’ exchange of regurgitated liquids between adult ants or adults and the larvae. While most folks understand what an ant looks like they may have trouble distinguishing an ant from a termite. Once you have determined you are indeed dealing with ants you should know that there a few species of ants that must be treated differently than getting rid of general ant species. Both leaf-cutter ants and their Trachymyrmex relatives cultivate a specialized fungus (white) in subterranean farms. The discovery by biologists from Rice University, Sao Paulo State University in Rio Claro, Brazil, and the University of Texas at Austin could provide new clues for controlling the agricultural and garden pests.
It began in 2000 and involved collecting, cataloging and analyzing samples of parasitic fungi called Escovopsis from dozens of colonies of leaf-cutter ants and their relatives in Brazil, Argentina, Panama, Mexico and the Caribbean islands of Guadeloupe and Trinidad and Tobago. Ecologists call the ants "mutualists" because they cooperate with another species for mutual benefit. Worker ants range widely, cutting and gathering leaves, which are brought underground into climate-controlled chambers where the fungal gardens are kept. Escovopsis was first identified about 25 years ago, and earlier studies suggested that it is highly specialized and found only in association with fungus-growing ants. It also found that Escovopsis is more of a generalist than was previously thought; the same genetic variant was found invading the farms of distantly related fungus-growing ant species, and as many as three different forms of Escovopsis were found in the same ant colony.


They cut and carry leaves back to their nest where they create an environment ideal to grow a special fungus which is used for food and antibiotics. This can be difficult to do because termites and ants do look very much alike, especially during the spring and fall when the winged cast members are starting to fly around to find grounds for a new nest. Inside, carpenter ants are usually found where wood has retained excess moisture from a leaky pipe or other leak in a void.
Ants can be a very wide variety of colors from very light tan to black, depending on the species. Researchers found that the same type of fungal parasites attack the farms of both Trachymyrmex and their leaf-cutter relatives. Each leaf-cutter species has its own mutualist partner, a fungus that it grows and cultivates for food and that in turn depends on the ants for food and shelter.
A leaf-cutter colony, which can be more than 60 feet deep and hundreds of feet wide, often contains dozens of farming chambers and millions of worker ants.
Evolutionary analyses suggested that Escovopsis co-evolved along with the ants and their fungal crops, since a different strain infects the fungal partners of each of the major groups of fungus-growing ants.
Such studies would be needed to fully understand how the parasite undermines a colony's health and how broadly it might be used against leaf-cutter species.
Shared parasites between leaf-cutting and non-leaf-cutting ants in the higher attine fungus-growing ant symbiosis, Royal Society Open Science (2015). They require controlled temperatures, humidity, a constant supply of fresh leaves, large space to collect leaves from, a suitable tank for fungus growing and a dumping tank.
