Abstract

The fungal genus Metarhizium has been used as an entomopathogen worldwide for approximately 140 years, and its mechanism of infection and its virulence factors have been studied. The present review is a compilation of virulence factors described in the literature to date and their participation in specific stages of the infection process.

Keywords: Host insect, metchnikoff, insecticides, appressorium, pathogenicity factors, mechanism of infection, biological control.
