Sequential utilization of hosts from different fly families by genetically distinct, sympatric populations within the Entomophthora muscae species complex.

The fungus Entomophthora muscae (Entomophthoromycota, Entomophthorales, Entomophthoraceae) is a widespread insect pathogen responsible for fatal epizootic events in many dipteran fly hosts. During epizootics in 2011 and 2012 in Durham, North Carolina, we observed a transition of fungal infections fr...
