Entomopathogenic fungi - a fascinating field of research

More than 800 species of fungi are described as pathogens of insects and other arthropods. Many of them play a significant role in the natural regulation of insect and mite populations. The best known representatives belong to the anamorphic fungi (Deuteromycota), to the Clavicipetales (Ascomycetes) and to the Entomophthorales (Zygomycota). Some of the anamorphic fungi are used as biocontrol agents but also as indicators to assess soil and farm management. Most entomopathogenic fungi are specialised and have a narrow host range. The highest degree of specialisation exists with the Entomophthorales which are not only closely adapted to their hosts but able to alter their behaviour in order to maximise their own reproductive potential.
