description Entomopathogenic fungi are important biological control agents throughout the world, have been the subject of intensive research for more than 100 years, and can occur at epizootic or enzootic levels in their host populations. Their mode of action against insects involves attaching a spore to the insect cuticle, followed by germination, penetration of the cuticle, and dissemination inside the insect. Strains of entomopathogenic fungi are concentrated in the following orders: Hypocreales (various genera), Onygenales (Ascosphaera genus), Entomophthorales, and Neozygitales (Entomophthoromycota). RESUMO: Os fungos entomopatogênicos são importantes agentes de controle biológico em todo o mundo e têm sido objeto de intensa pesquisa por mais de 100 anos, infectando artrópodes na natureza e podendo ocorrer em níveis enzoóticos ou epizoóticos em suas populações de hospedeiros. O seu mecanismo de infecção envolve a fixação do esporo à cutícula do inseto, seguido da germinação, penetração da cutícula e disseminação interna no inseto. As linhagens dos fungos entomopatogênicos estão concentradas nas ordens: Hypocreales (vários gêneros), Onygenales (gênero Ascosphaera), Entomophthorales e Neozygitales (Entomophthoromycota).
