The genus Entomophthora belongs to the early-diverging subphylum Entomophthoromycotina, Footnote 1 which includes fungi such as the genera Basidiobolus and Conidiobolus that can cause a wide range of infections and complications in invertebrates, cold-blooded animals and even humans. Species in the genus Entomophthora are fungal pathogens of a variety of insects, most of which elicit dramatic behavioral changes in their host for the invading fungusвЂ™ benefit. Finally, we propose six major directions for future Entomophthora research and in doing so hope to provide a foundation for future studies of these fungi and their interaction with insects. We argue that the high host-specificity and obligate life-style of most Entomophthora species provides ample scope for having been shaped by close coevolution with insects despite the current general lack of such evidence.

However, we are only starting to understand the functions of unusual molecular and genomic characteristics, such as having largeвЂ‰>вЂ‰1В Gb genomes full of repetitive elements and potential functional diploidy.

We discuss evidence for EntomophthoraвЂ™s adaptation to growth exclusively inside insects, such as producing wall-less hyphal bodies and a unique set of subtilisin-like proteases to penetrate the insect cuticle. A detailed description of EntomophthoraвЂ™s life-cycle and observed manipulated behaviors is provided and used to summarize a consensus for ideal growth conditions. Evidence for strain-level specificity of hosts is summarized and directly compared to phylogenies of Entomophthora and the class Insecta. Further, we argue that this genus is globally distributed, based on a compilation of Entomophthora records in the literature and in online naturalist databases, and likely to contain additional species. We briefly review the discovery of Entomophthora and provide a summary of the 21 recognized Entomophthora species, including their type hosts, methods of transmission (ejection of spores after or before host death), and for which molecular data are available. This review provides a comprehensive overview of our current understanding of the biology of Entomophthora fungi and enumerates the most pressing outstanding questions that should be addressed in the field. Despite having been first described more than 160В years ago, there are still many open questions about Entomophthora biology, including the molecular underpinnings of host behavior manipulation and host specificity.

muscae, which, like other Entomophthora species, elicits a series of dramatic behaviors in infected hosts to promote optimal spore dispersal.

The most well-known among these is the вЂњzombie flyвЂќ fungus E. The fungal genus Entomophthora consists of highly host-specific pathogens that cause deadly epizootics in their various insect hosts.
