title: Factors affecting transmission of fungal pathogens of aphids.
abstract: Fungal pathogens are the most important pathogens of aphids (Homoptera: Aphididae), and epizootics, particularly those caused by Entomophthorales (Zygomycota), are frequently observed and often rapidly reduce aphid populations. Fungi in the Hypocreales (Ascomycota) are less commonly found infecting aphids but can be important. The transmission of aphid fungal pathogens is affected by many factors, including: host biology and structure, pathogen characteristics, host-plant characteristics, and environmental factors. This paper is an overview of selected factors affecting transmission of aphid pathogens.
