Entomophthorales

[‚ent·ə‚mäf·thə′rā·lēz]
(mycology)
An order of mainly terrestrial fungi in the class Phycomycetes having a hyphal thallus and nonmotile sporangiospores, or conidia.

Entomophthorales

 

an order of fungi of the class Phyco-mycetes. The mycelium is reduced and frequently divided into irregular shaped sections called hyphal bodies. During fusion the bodies form zygospores or divide by means of budding. Some cells form conidiophores, each of which carries one conidium. A characteristic feature of the Entomophthorales is their ability to throw off ripe conidia with considerable force and for great distances. Entomophthorales can be parasites of insects, protozoans, and nematodes. Some live as saprophytes on dead insect tissue.

The order embraces approximately 150 species, belonging to 28 genera. They are found throughout the world.

This prediction was investigated in two different ways: by comparison of the level of asymmetry of flies that had died from infections by the entomopathogenic fungus Enthomophthora muscae (Zygomycetes, Entomophthorales) with the asymmetry of the nearest neighboring fly that had died for other reasons, and by estimating the likelihood of developing infections by the parasitic fungus for previously uninfected flies differing in their degree of asymmetry.
