Hyphal bodies of E. The fungus is sensitive to temperature and when the air temperature is high, the prevalence of the disease decreases to very low levels.

Entomophthora muscae – Wikipedia

In the evening hours, critically ill insects tend to crawl up verticle surfaces to die at an elevated position. Soon after a fly dies from infection with this pathogenic fungus, large primary conidia are produced at the apex of a conidiophore which emerge from the intersegmental membranes. Such environmental conditions promote primary conidial production and disease transmission.

Habitat Entomophthora muscae epizootics usually occur in the spring and fall of the year, and occur in most temperate regions. The fungus replicates in the fly hemolymph, and progressively consumes all the hemolymph in about days.

Watson Relative Effectiveness Epizootics appear to be influenced by abiotic factors, particularly temperature Watson and Petersen ARS Catalog of Strains.

The fungus is found in most temperate regions and sporulation usually takes place in cool, humid conditions in areas where flies congregate and rest.

Colonies are usually maintained through direct fly to fly transmissions. Pages People more options. In agricultural settings, fly cadavers may be seen attached to the underside of plant leaves, along field margins, on fence rails and feed bunks, and in dairy barns and poultry houses.

The hyphae gradually grow through the whole of the body, digesting the guts, and the fly dies in about five to seven days. Views Read Edit View history. Pesticide Susceptibility Insecticide residues significantly inhibited the germination of primary conidia Mullens and Rodriguez, Large primary conidia are produced soon after the fly dies, but in the event no hosts are available for the primary conidia, a smaller secondary conidia may develop from the primary conidia.
