Ophiocordyceps myrmecophila is a species of fungus that parasitizes insect hosts, in particular members of the order Hymenoptera. [1]
Ophiocordyceps myrmecophila has been noted as one of the more dominant entomopathogenic fungi of formicine ants in the tropical rainforests of Thailand. [1] This species and others like it can parasitize multiple arthropod hosts. Although entomopathogenic fungi have been identified as a widespread organism, tending obviously to be found in similar habitats to that of their arthropod host; ubiquity of the host, as well as evolutionary cospeciation are key factors of host specificity and therefore location.
The new genus was separated recently from an 'outdated' entomopathogenic genus, Cordyceps , due to DNA analysis and phylogenetic differences in stromata and apices. [2]
Ophiocordyceps sinensis, known colloquially as caterpillar fungus, is an entomopathogenic fungus in the family Ophiocordycipitaceae. It is mainly found in the meadows above 3,500 metres (11,500 ft) on the Tibetan Plateau in Tibet and the Himalayan regions of Bhutan and Nepal. It parasitizes larvae of ghost moths and produces a fruiting body which is valued in traditional Chinese medicine as an aphrodisiac. Caterpillar fungus contains the compound cordycepin, an adenosine derivative. However, the fruiting bodies harvested in nature usually contain high amounts of arsenic and other heavy metals, so they are potentially toxic and sales have been strictly regulated by China's State Administration for Market Regulation since 2016.
Cordyceps is a genus of ascomycete fungi that includes about 600 worldwide species. Diverse variants of cordyceps have had more than 1,500 years of use in Chinese medicine. Most Cordyceps species are endoparasitoids, parasitic mainly on insects and other arthropods ; a few are parasitic on other fungi.
Beauveria bassiana is a fungus that grows naturally in soils throughout the world and acts as a parasite on various arthropod species, causing white muscardine disease; it thus belongs to the group of entomopathogenic fungi. It is used as a biological insecticide to control a number of pests, including termites, thrips, whiteflies, aphids and various beetles. Its use in the control of bedbugs and malaria-transmitting mosquitos is under investigation.
Beauveria is a genus of asexually-reproducing fungi allied with the ascomycete family Cordycipitaceae. Its several species are typically insect pathogens. The sexual states (teleomorphs) of Beauveria species, where known, are species of Cordyceps.
Ophiocordyceps unilateralis, commonly known as zombie-ant fungus, is an insect-pathogenic fungus, discovered by the British naturalist Alfred Russel Wallace in 1859, and currently found predominantly in tropical forest ecosystems. O. unilateralis infects ants of the tribe Camponotini, with the full pathogenesis being characterized by alteration of the behavioral patterns of the infected ant. Infected hosts leave their canopy nests and foraging trails for the forest floor, an area with a temperature and humidity suitable for fungal growth; they then use their mandibles to attach themselves to a major vein on the underside of a leaf, where the host remains after its eventual death. The process, leading up to mortality, takes 4–10 days, and includes a reproductive stage where fruiting bodies grow from the ant's head, rupturing to release the fungus's spores. O. unilateralis is, in turn, also susceptible to fungal infection itself, an occurrence that can limit its impact on ant populations, which has otherwise been known to devastate ant colonies.
Hirsutella is a genus of asexually reproducing fungi in the Ophiocordycipitaceae family. Originally described by French mycologist Narcisse Théophile Patouillard in 1892, this genus includes species that are pathogens of insects, mites and nematodes; there is interest in the use of these fungi as biological controls of insect and nematode pests. The teleomorphs of Hirsutella species are thought to belong to the genus Ophiocordyceps.
Metacordyceps is a genus of fungi in the family Clavicipitaceae. The anamorphs of Metacordyceps appear to include Metarhizium species.
Ophiocordycipitaceae is a family of parasitic fungi in the Ascomycota, class Sordariomycetes. It was updated in 2020.
Ophiocordyceps is a genus of fungi within the family Ophiocordycipitaceae. The widespread genus, first described scientifically by British mycologist Tom Petch in 1931, contains about 140 species that grow on insects. Anamorphic genera that correspond with Ophiocordyceps species are Hirsutella, Hymenostilbe, Isaria, Paraisaria, and Syngliocladium.
Hymenostilbe is a genus of fungi in the Ophiocordycipitaceae family. All members are anamorph names of Ophiocordyceps.
Paraisaria is a genus of fungi in the Ophiocordycipitaceae family. Members are anamorph names of Ophiocordyceps.
Syngliocladium is a genus of anamorphic fungi within the Ophiocordycipitaceae family. Members are anamorph names of Ophiocordyceps.
Tolypocladium is a genus of fungi within the family Ophiocordycipitaceae. It includes species that are parasites of other fungi, insect pathogens, rotifer pathogens and soil inhabiting species with uncertain ecological roles. Tolypocladium was originally circumscribed as a genus containing anamorphic fungi. It was later determined that some Cordyceps-like teleomorphic fungi were the teleomorphs of Tolypocladium species. These species were considered to belong in the genus Cordyceps until molecular phylogenetics studies found these species to be more closely related to Ophiocordyceps and were considered to belong in that genus before they were transferred to the new genus Elaphocordyceps by Sung and colleagues in 2007. However, under the ICN's 2011 "one fungus, one name" principle, fungi can not have different names for their anamorphic and teleomorphic stages if they are found to be the same taxon. Quandt and colleagues formally synonymized Tolypocladium and Elaphocordyceps in 2014. Quandt and colleagues also synonymized the anamorphic genus Chaunopycnis with Tolypocladium. The immunosuppressant drug ciclosporin was originally isolated from Tolypocladium inflatum, and has since been found in other species of Tolypocladium, some of which were formerly placed in Chaunopycnis.
Thitarodes caligophilus is a species of moth of the family Hepialidae. It is found in Bhutan. It is a host of the entomopathogenic fungus Ophiocordyceps sinensis, a species of the genus Cordyceps. The fruiting bodies of Ophiocordyceps sinensis are used extensively in Traditional Chinese medicine. As a result, T. caligophilus-sourced Cordyceps harvested in Bhutan have become "widely used".
Ophiocordyceps nutans is an entomopathogenic fungus belonging to the order Hypocreales (Ascomycota) in the family Ophiocordycipitaceae. O. nutans only parasitizes Hemipterans, namely stinkbugs. In Korea, O. nutans is one of the most common species of Cordyceps. O. nutans, as well as other Cordyceps species, are mainly classified morphologically by their colour, fruit body shape, and host insect species. Stinkbugs cause considerable damage to agriculture and forestry, and the anamorph of O. nutans, Hymenostilbe nutans, is a potential selective biological control agent against the stinkbugs.
Zoophthora is a genus of fungi in the family Entomophthoraceae. Like other taxa in this family, Zoophthora species cause disease in insects and as such are considered entomopathogenic fungi.
Cordyceps militaris is a species of fungus in the family Cordycipitaceae, and the type species of the genus Cordyceps. It was originally described by Carl Linnaeus in 1753 as Clavaria militaris. There are hundreds of species of cordyceps fungi. Special characteristics of Cordyceps Militaris are its use in traditional Chinese medicine, modern pharmaceuticals, and its relationship with insects and how it disperses.
Ophiocordyceps formicarum is an entomopathogenic fungus belonging to the order Hypocreales (Ascomycota) in the family Ophiocordycipitaceae. The fungus was first described by mycologist George S. Kobayashi in 1939 as a species of Cordyceps. Originally found in Japan growing on an adult Hercules ant, it was reported from Guizhou, China, in 2003. It was transferred to the new genus Ophiocordyceps in 2007 when the family Cordycipitaceae was reorganized. A technique has been developed to grow the fungus in an agar growth medium supplemented with yeast extract, inosine, and glucose.
Ophiocordyceps robertsii, known in New Zealand as vegetable caterpillar is an entomopathogenic fungus belonging to the order Hypocreales (Ascomycota) in the family Ophiocordycipitaceae. It invades the caterpillars of leaf-litter dwelling moths and turns them into fungal mummies, sending up a fruiting spike above the forest floor to shed its spores. Caterpillars eat the spores whilst feeding on leaf litter to complete the fungal life cycle. Evidence of this fungus can be seen when small brown stems push through the forest floor: underneath will be the dried remains of the host caterpillar. This species was first thought by Europeans to be a worm or caterpillar that burrowed from the top of a tree to the roots, where it exited and then grew a shoot of the plant out of its head. It was the first fungus provided with a binomial name from New Zealand.
Ophiocordyceps dipterigena is an entomopathogenic fungi species from the genus Ophiocordyceps. This species was originally described in 2007.
